The Buzz Audio SOC-20 Compressor is optimized for the stereo buss with features not found on any other LDR compressor manufactured today.
The Buzz Audio SOC-20 Compressor uses their proprietary Class A discrete transistor BE41 amplifiers with a Lundahl LL1517 transformer at the output. A special low impedance power supply design is used to enhance the sound quality of the amplifiers by providing very stiff power rails. This overall combination produces a unique sound character with full bass and a vibrant top end void of any midrange harshness. Whilst the SOC-20 is not a clone of any vintage units, it's design is inspired by the use of the LA2 and LA3 by it's designer Tim Farrant.
Not only can the SOC-20 be used in dual mono or stereo mode, we have also incorporated a Mid-Side (or sum and difference) encoder and decoder. When set to MS mode, the stereo input is divided into signals that are common to left and right (called the mid) and signals that are not (called the side). The divided signals are sent to each channel of the SOC-20 then recombined at the output thereby allowing you to adjust the dynamics and width of the stereo image. This process has application on a wide range of stereo sounds including the mix buss and electronic music sub mixes. Check out the audio samples to see how powerful this process can be. At the flick of a switch, a high pass filter reduces the compressor sensitivity to low frequencies for more bass punch when used on program material. We have also included a fully balanced side chain insert point so you can add additional equalisation to the compressor characteristic or "key" the compressor with another source to create those pumping effects found in modern music styles. The side chain monitor function allows you to hear what is returning into the insert point and also monitors the mid or side signal when the compressor is used in MS mode.
Buzz Audio SOC-20 Compressor Features
- DRIVE - variable pot that sets the amount of compression.
- OUTPUT dB - variable pot that adds gain at the output to correct for lost level.
- ATTACK - rotary switch with 1mS, 10mS, 25mS, 50mS selections and the excellent AUTO mode.
- RATIO - rotary switch with 2:1, 4:1, 6:1, 10:1 and 20:1 selections - all soft knee characteristic.
- RELEASE - rotary switch with 100mS, 200mS, 400mS, 800mS 1600mS selections and our superb AUTO mode.
- BYPASS - hard wire unit bypass to compare compressed and uncompressed signals.
- METER - switches the VU meter between input/output levels or amount of compression.
- S/C HPF - inserts a 170Hz high pass filter into the side chain for added bass punch.
- S/C INSERT - engage the external side chain insert point and monitor the side chain signal.
- LINK A/B - joins the side chain of each channel for stereo operation with "soft" tracking.
- There is also a locking toggle to select STEREO or MID-SIDE mode and a handy POWER on/off switch.
- On the rear panel for each channel, there are 1 set of female/male XLR connectors for the main input and output, plus another male/female XLRs for the side chain insert send and return.
