Wired as pin 1 earth, pin 2 earth, pin 3 hot. Harmonic distortion in this type of equipment will increase with reduced frequency and shorter time constants. A two part program-dependent time constant. Frequency is that at which 3dB of gain reduction occurs for 10dB of signal overdrive above threshold. 10dB of gain reduction will occur at and above twice this frequency.
Power supply is designed with high low-voltage tolerance to meet road show requirements.
For applications which require a recessed blank front panel unit, a security cover kit is available to convert the DPR402 into a fully tamper-proof rack mounting unit. All front panel controls are then hidden behind a blank steel panel. A separate output balancing unit is available to provide full transformer balanced and floating output sends to drive 600 ohm loads. The DPR402 has internal insertion points on the control and subtract side-chains so that fixed filter networks can be fitted giving users any standard form of emphasised contouring to the compressor action. This does not interfere with the normal de-essing functions.
