312 Preamp on bass drum
September 19, 2024
I use the HA Lang 312L as a replacement for the Warm Audio WA12. According to the item name, they are both based on API 312, which I haven't tested yet for reference, and they both "play" in the same price range. When comparing the 312L to the WA12, I noticed the following differences: - The kick drum sound on the 312L is audibly "crisp" - The "click" sounds "brighter" on the 312L and feels "faster" - The look and feel The feel of the 312L is a little more valuable than that of the WA12. Both preamps record the kick drum very well, but I like the 312L a little better. The bass drum sounds more aggressive, we play alternative rock. I don't regret the purchase! I split the BD signal during testing for better comparison. However, my structure was neither meticulous nor scientific. ?// Orangeboogie

I found the most underrated and underpriced preamp! Whats it sound like?
March 12, 2025
Punchy. Crunchy. Thumpy. Chunky. But if i hade to sum it up in one word: present. It makes the tone sound like its being beamed directly into your ear drum but in a pleasing and musical way. I wanted something api flavor. The 512c and v were more than i felt like spending, and every knows the warm wa12 and has an opinion. Since im an an unknown, i took a risk on a fellow underdog and i dont regret. I dont have detailed knowledge of the 512, but this sounds so good that im not actually worried at all.// Nick battaglia from Denton, TX

This preamp has a DI that is truly hi-impedance: greater than 2 Meg ohm. It will easily accomodate a peizo pickup or the output of a regular guitar and not be compromising the sound due to impedance issues.

Good delivery of API-sound
August 23, 2025
The Heritage Audio Lang 312L is a good delivery of the API sound, generally speaking. It compares well on a lot of set ups with my C A P I VP 312, which is a high mark to meet. It delivers upon the promise of the input transformer / Discrete Opamp / steel core output transformer design that the API-style preamps were built upon. It is using API-standard plug in format for the discrete opamp, which is very cool because you can swap out the Heritage designed and supplied opamp for something different if you ever decide to do that. The price is certainly VERY nice and for the price, Heritage did not cut corners on some important components like the input and out transformers, so that is all a total win.// Sweetwater Customer

Optical Tube Compressors have been the choice of seasoned engineers and producers for recording critical signals such as voice where it is essential to retain all the individual character and emotion while offering a natural, transparent control… Now, Heritage Audio has released its take on this venerable classic, the TUBESESSOR.
A unique design manufactured in the EU with top-of-the-line components, custom transformers at the input as well as output and NOS tubes operating at an extremely high internal voltage to ensure a clarity, depth and headroom previously unheard of.
Not only is the TUBESESSOR the perfect choice for warming up and slightly enhancing a signal subtly all while maintaining total dynamic control, but it also has a few tricks up its sleeve…

KNOW ME

The TUBE SATURATION section allows you to add in a taste of attitude with 4 settings varying from CLASSIC, no saturation at all, to HOT, an angry tone ready for a fight. This greatly increases the tonal options you can achieve with the TUBESESSOR therefore making it much more flexible than any other optical tube compressor out there.

Heritage Audio has also opted to include its legendary sidechain filter section to expand control even more with five internal sidechain settings to choose from. Two of the settings make sure the compressor is not being unfairly overpowered by lower frequencies and the other three are frequency specific options for extra creativity.Continuously adjustable ATTACK & RELEASE controls in addition to a FIXED mode and a combination of the two will provide all the necessary settings possible, allowing you to mold your signal exactly as you´d like.

A huge, attractive custom VU meter for monitoring either Input, Output or Gain Reduction guarantee you´ll always be informed with a clear reading of exactly what is happening.Everything you could possibly require to achieve a top-notch professional recording. TUBESESSOR, the optical tube compressor for when you need the sweetest, warmest most natural dynamic control possible, but also want the ability to spice it up on occasion.As is the case with other tube offerings from Heritage Audio, the company has sourced NOS tubes for a lifetime, making sure your investment is safe and sound.

It's sounding amazing
March 1, 2023
I've been waiting for almost a year to get a CL1B, I wouldn't even find it used for $5K. So I made my own research and found two Engineers on Instagram that own CL1B & the Tubesessor. they sent me comparison Videos and told me don't hesitate just get the Tubesessor it's Sounding Amazing & got more Features than than CL1B. I literately sold all my Warm Audio Compressors & Preamp to get the Tubesessor.Ovince Music

Absolute monster
January 12, 2023
I seriously had my eyeball on the Cl1B. This unit seems to be the better purchase for a couple of reasons: 1. Cost - self explanatory when you look up the cost of the Tubesessor vs. the CL1B. Now, that doesn't mean quality is lesser or bad . This thing outperforms its price point. 2. Features - the fact that we get to choose how to warm up the sound of signal right on the unit is incredibly handy. Paired with the flexibility of my LCT 1040, I couldn't ask for a more versatile recording chain 3. Sound - It sounds just as you'd expect a CL1B to sound - incredibly smooth, superior top end. Again, the added saturation feature sets it apart so I can get as gritty or as clean as I'd like. 4. Build Quality - Solid unit, lighter than expected, nonetheless it's still a beast. Reactions from clients - the look of this thing is nice and attractive. New customers have booked sessions just to hear what they would sound like. Some have said that I've accomplished the best quality in the area which is tremendous as I am yet a small studio owner. Others have openly said that I'll be their new go-to for recording which I attribute to the absolute monster that is the Tubesessor. It's really opened up new waves of possibilities in my studio and I am very happy. I've gotten a bit of feedback from other owners and they say that the Tubesessor is very sibilant, I have found that since it's such a clean sounding compressor, that would occur if someone paired a brighter mic with the unit (e.g. C-800g - or a clone, AKG414, TLM103). Since the Tubesessor has the saturation options, this issue can easily be compensated for to soften the increased top end of certain mics. CONS - I don't have a second one hahaTory G. from VIRGINIA BEACH

Great addition to my rack!
November 10, 2023
I only received the Tubesessor today, so I'll want more time and space with it. That said, I've curated my rack gear over the past few years to create a bit of a vintage sound, and I already hear that the a Tubesessor is a great addition to my Chandler Limited, API, Heritage Audio , SPL, and other gear. After getting it in the rack, I ran a few female vocal and bass recordings through it with the Heritage Audio Motorcity EQ (vox) and Lang PEQ (bass). I'm really impressed. Yes, it's a compressor and serves that function well…the sculpting the compressor does is truly nice. The side chain filter was really effective in dialing in the sound I wanted. The choices for tube saturation can be pushed a bit to far in combination with the gain control lol, but I imagine it would work nicely adding harmonics and saturation when needed. It's a beautiful unit and does what it should, while imparting a subtle (when wanted) sound. I'm already thinking this could be a desert island compressor.Bob Eldon from Portland, OR

We gave our engineers what sounded like a simple brief: improve the Baby R.A.M for our 15th anniversary. After weeks of revisiting the original design, the conclusion was unanimous—there was nothing to improve.HOW TO IMPROVE A TOP SELLING PRODUCT?In a world where technology moves fast, some things don’t benefit from change. A pure, passive design built with top-tier components—like the Baby R.A.M—doesn’t get more transparent than 100% transparency. And you can’t meaningfully improve the usability of a category-defining, best-selling monitor controller that’s already proven itself for several years now.So what was left to do?We went through every photo, every comment, every review we could find and the only recurring criticism of the Baby R.A.M had nothing to do with performance: It was the look.While the original Baby R.A.M proudly channels the spirit of classic vintage consoles—with its RAF blue-grey metalwork and oversized, irresistibly smooth Marconi knob—not everyone connected with that aesthetic.And that’s where this story really begins.

[H2] SAME GUTS, NEW ATTITUDE

This edition keeps the exact signal path thousands of engineers trust: ultra-transparent passive attenuation, zero coloration, and absolute reliability. No compromises, no redesigns, because when something already works, you don’t mess with it.Same internals. Same circuit. Same reason it’s been the top-selling passive monitor controller for almost a decade. What has changed is the attitude.Clad in a deep black finish, this edition steps away from the blue-grey, vintage-console nostalgia, opting for a cleaner, more modern and smarter look. To match the satisfying feeling of a Marconi knob, we’ve user an equally satisfying RCA type black knob and, of course, the same perfectly stepped attenuator that made the Baby R.A.M the legend it is.

[H2] KEEPING INTACT THE SPIRIT OF THE GREATEST PASSIVE MONITOR CONTROLLER OF ALL TIME

Heritage Audio’s Baby R.A.M has been the ultimate passive-monitoring system for the past 6 years, delivering the most transparent signal with the best stereo imaging of any other passive designs available! A Baby R.A.M is the ultimate controller for total transparency — a zero-compromise signal path, paired with a simplified control set ensures your monitors receive the cleanest, purest signal possible without unnecessary complications.The Baby R.A.M proudly features a 4-gang, 24 step rotary switch for volume as opposed to cheaper stereo potentiometers, which means the precision of your stereo signal is perfect on every position as well as offering a subtenth of a dB precision on every single attenuation position! Baby RAM also has no insertion loss, meaning that there’s no extra coloration, signal loss or degradation at any settings.Even though the Baby R.A.M packs a zero-compromise circuit design, it couldn’t be any easier to use with 2 pairs of stereo inputs and outputs — both balanced and ground free (unbalanced compatible) on gold-plated TRS 1/4¨ jacks. Mute, Dim, Mono, and Volume monitoring controls make the Baby R.A.M a breeze to work with. And with its passive design, it also means you have no concerns with bad power supplies, as no electrical current is needed!The Baby R.A.M is built with the most cutting edge methods in manufacturing and design, without ever compromising audio quality or cutting corners.

Absolutely color free volume controller
December 7, 2020
I've been using an old JBL RMC controller which is a digital device, very poor build quality and not transparent by any stretch of the imagination. The JBL was sitting between my Lynx Aurora and my Adam A7X's and was definitely the weakest link in my signal chain. The Baby R.A.M. is a perfect replacement since it's totally passive. Just think of it as a switch selectable pad for your powered speakers. It does NO coloration whatsoever and is so clean I'm going to get one for our commercial studio. I pre-ordered it months ago but it was well worth the wait. I also love the chicken-head knobs and color which matches my BAE 1073MP.//Paul

Great Little Unit
March 31, 2021
Great little unit. No added noise or coloration to signal chain. The knob feels cheap because it's cheap plastic but can easily be swapped out. Mono and Mute buttons sometimes pass slight crackles making it not entirely silent. But these sounds only occur when the button is pressed and it's quiet enough not to cause concern or bother.// Jf

Much more flexible than Mackie
July 7, 2022
I picked this up because my sub's stereo outputs died and I could not feed my monitors from the sub. This little beast has a unique feature that lets you use both outputs at the same time. Simply push both output buttons at the same time and boom, you have two outputs feeding two different speakers. You could do the same for the inputs, but I would advise against it. The Baby Ram is very neutral and I could not hear any coloration. I liked my Mackie, but the Baby Ram is just a joy use and is more flexible. I got the B stock and it looked just like new. I highly recommend.// Steven

Much more than I’d bargained for!
June 6, 2022
I didn't really NEED one of these. I'd added one to a wish list awhile back as a "maybe eventually" luxury item. But when the happy confluence of a demo unit becoming available and me having funds to match, I decided to go for it. With my very first tracking session after acquisition, I immediately discovered this is no mere luxury item! Honestly, the main reason I was thinking to get one in the first place was to just not pop my monitors whenever the mixer came up, since I could never get those to synch nicely. So yes, the mute switch is a nice help. But then I didn't have any more excuses to not hook up the extra "trash can" monitors — and what a difference it makes being able to switch between those for knowing what's happening to my finals! Having another point I can route out from the mixer that I can switch in from source is also a nice bonus. But, as silly as it may sound, just having that Mono switch there is practically worth the cost and value alone! Being able to fold down the stereo mix, check my phasing, hear it in the trash cans, and all without having to screw with the mix config has improved my results dramatically, whilst also improving my workflow. Bottom line: if you are producing something you intend other people to listen to, you need something like this.// Stranger Pearl Productions
