The TLA-50 Tube Leveling Amplifier is a single channel tube leveling amp offering XLR +4dB and -10dB inputs and outputs. -
SPL (Sound Performance Lab)
The Kultube is a stereo compressor with discrete gain cells (instead of VCAs). It offers "Progressive Time Control", a user optimization of attack and release times that work in conjunction with the unit's signal responsive circuitry to provide the best attributes of manual and auto compressors at the same time. Another feature is adjustable tube saturation with automatic output level adjustment. -
Portico (Rupert Neve Designs)
The Portico 5043 embodies two independent Compressor-Limiters (Channels A and B) housed within a half rack, 1U module. They can be used independently or connected in sequence to provide two separate control slopes. -
Langevin
Langevin ELOP® Limiter's principle of operation is based around using a rectified sample of the audio to shine an LED (Light Emitting Diode) onto an LDR (Light Dependent Resistor). The photo-resistor in combination with a fixed resistor simply act as a changing voltage divider to attenuate the signal-- like a smart volume control. -
DBX
DBX offers a multitude of dynamics processors. Since its introduction in the mid 1970's, the dbx 160 series has been the world's most popular line of audio compressors. After the classic 160 (which is still used daily in many world class studios), came the 165, the 160X and the 160XT. The 160X/XT were the models that truly became the industry standard. -
Universal Audio
Universal Audio's full line of compressors is anchored by the 1176LN designed by Bill Putnam. It was a major breakthrough in limiter technology – the first true peak limiter with all transistor circuitry offering superior performance and a signature sound. The other anchor in their compressor line-up is the Teletronix LA-2A Leveling Amplifier. A unique electro-optical attenuator system allows instantaneous gain reduction with no increase in harmonic distortion. -
Groove Tubes
The Groove Tubes Glory Comp is a true all-tube compressor, employing seven high-quality and selected vacuum tubes to accomplish its dynamics processing. Its output tubes – a pair of 6005s – offer tremendous output power driving a custom wound and robust output transformer.
-
Focusrite
The Compounder is derived from the legendary Red 3 Dual Compressor/Limiter. This custom VCA design results in superb sound and very low distortion. The bass expander circuit generates extra bass harmonics, fattening up low frequency signals. The Red 3 dual compressor/limiter is fully discrete and balanced, offering superb low noise and distortion, and excellent common-mode rejection. -
Daking
The Fet Compressor II uses all discrete transistor circuitry with transformer balanced inputs and outputs. Class "A" amplifiers are employed. -
EAR (Esoteric Audio Research)
The EAR 660 limiter is somewhat based on the legendary Fairchild 660. The characteristics of the 'compression knee' around the attack and release parameters contribute to the unit's performance. -
Avalon Design
The AD2044 features a 100% discrete, pure class A signal amplifier configured with high speed current monitored optical control elements. These "invisible" opto elements enable the AD2044 to deliver totally transparent, low noise gain reduction within the minimalist signal path design. No VCAs are incorporated. -
Peavey
The CEL-2a Compressor/Expander/Limiter is designed for use in all live performance and recording applications, and can be incorporated as either two independent compressors or one synched stereo compressor with true RMS summing. Voltage-controlled amplifier and RMS-integrated circuits maintain low distortion and excellent noise performance. -
TC Electronics
TC Electronics offers many different types of dynamics processors. The C300 is an easy to use dual engine dynamics processor that gives you superior compression/limiting and gate/expansion feasibilities. The C400XL uses advanced TC Electronic multiband dynamics technology to compress any source - from vocals and percussion to guitars and even keyboards. If you want the sound of a full band/one band compressor you can do that too; even de-essing and de-hiss is an option. -
Waves
The Waves MaxxBCL is a mastering and post production dynamics processor that employs three separate functions. The first is a full arrangement of compressor controls. Next are the MaxxBass controls. The final stage is the limiter section. -
Toft Audio
The DC-2 offers two channels of classic F.E.T compressor with variable attack, release and ratio. V.U. metering shows gain reduction or output level. -
TL Audio
The C-1 two channel tube compressor uses General Electric US military specification valves, high retention gold plated ceramic valve bases and circular back-lit VU meters. The 5021 two channel tube compressor employs two valve stages per channel, in the form of a Sovtek ECC83/12AX7A twin triode valve run from a stabilised 150V DC supply. One stage is in the preamp, and the other is in the gain control element of the compressor. -
Presonus
The COMP16 is an easy to use professional quality compressor. Sixteen presets have been tailored for a wide range of applications including vocals, percussion, fretted instruments, keyboards, stereo program material and compression effects. Simply select the preset and adjust the input and output to desired level of compression. A compressor that anyone can use! -
