Chameleon Labs 7720

The Model 7720 Stereo Compressor is based on a trusted design and is electronically balanced, utilizing "THAT corporation" (formerly dbx) VCA circuitry. It features a low component cound in order to provide the cleanest signal path possible. In accordance with Chameleon Labs' ongoing dedication to end users, unique features have been implemented (direct from consumer suggestions) to make the 7720 more versatile than your average mix buss compressor.

Features

  • Meter Switch
    The meter switch allows the meter to indicate either channels input level, either channels output level or the amount of stereo audio signal compression
  • Sidechain
    This section modifies the control of the compressor with a mono audio signal introduced through the sidechain XLR input. A blue LED gives the user a visual indication that the circuit is active and that the sidechain audio is in control of the compressor, not the left and right audio inputs.
  • High Pass Filter
    The HPF rotary control allows the sidechain or main audio signal to be equalized to minimize lower frequency audio signals' effect on the compression character of the unit. The HPF affects the detection circuit, not the actual audio. The selector has six settings. The first setting does not introduce any filtration into the sidechain circuit. The next five settings are 60Hz, 90Hz, 130Hz, 200Hz and 440Hz. These selections allow a wide variety of choices. The high pass filter is designed so that the frequency selected is 3dB down, with a roll-off of 12 dB per octave.
  • Ratio
    In addition to the ratio settings common to popular stereo compressors (2:1, 4:1, 10:1), the 7720 features a 1.5:1 setting. This allows the user to maintain control over the dynamics of the input signal without squashing the life out of the mix.
  • Non-Stereo Application
    In order to use the Model 7720 as a mono compressor, you need only use the left channel inputs and outputs. All functions are as normal
  • Power Options
    24VAC Adapter: Each model 7720 ships with a mid-line power supply, type-dependent on country of operation. This is not a traditional "wall-wart" but simply an outboard AC transformer. DC filtering and regulation is accomplished inside the 7720 itself.
    CPS-1 Dual Power Supply: For users who prefer a rack-mounted power option, the Model 7720 may instead be powered by the CPS-1 Dual Power Supply. The CPS-1 is offered as an optional accessory and can provide power to two 7720 units.
