BSS DPR-402 Dual Compressor/De-Esser/Limiter £1,249.82
Description
The DPR-402 is a 2-channel compressor/limiter, high frequency de-esser and wide band de-esser with peak limiting, adjustable speed, dynamics program manipulation, and full LED metering for both input and output.
Integrated side-chain and gain reduction metering allow for continuous dynamic activity monitoring.
Auto mode provides program dependant attack and release control.

- System Performance
- Frequency Response + 1dB 25Hz-20kHz. Ultrasonic filter -3dB@ 30kHz.
- Noise Equiv. input noise -86dBv 22Hz -22kHz, -82dBv CCIR weighted.
- Distortion Unity gain, + 10 dBm output, below threshold: THD 0.03% 20Hz-20kHz.
- IMD 0.01%SMPTE, 10 dB compression.
- Threshold 0dB. 1kHz, 5 sec rel. time setting: 2ND HARMONIC 0.15%.
- 3rd Harmonic 0.05%. IMD 0.25% SMPTE.
- Harmonic distortion in this type of equipment will increase with reduced frequency and shorter time constants.
- Crosstalk better than -85dB 20Hz -20kHz.
- Compressor
- Threshold -30 to +20 dBv cont. variable.
- Compression Ratio 1:1 continuously variable to infinity:1.
- Max. VCA Range 30dB.
- Attack Time 11 steps 50µsec-80msec.
- Release Time 10 steps 5msec to 5 sec and AUTO.
- Attack times are measured at 63% of final gain reduction with step signal 8dB above threshold. Release times are measured at 63% of open gain or removing a signal 8dB above threshold.
- Auto Time Constant A two part program-dependent time constant. Typical attack time is 200 µsec on fast transients, release time 10msec for 63% recovery from a 10dB 4msec response, and 1 sec for a 10dB 40 msec response.
- De-esser
- Threshold Range -30 to +20 dBv continuously variable.
- Ratio Infinite, at and above twice the set frequency.
- Frequency Range 800Hz to 15kHz continuously variable. 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.
- Peak Limiter
- Threshold Range +4dBv to +20dBv continuously variable.
- Ratio 20:1.
- Attack Time Fast setting 150µsec, Slow setting 750µsec.
- Release Time Fast setting 100msec, Slow setting 500msec.
- Dimensions and Electric's
- Size 482 x 44 x 228mm (19in x 13/4in x 9in) overall.
- Weight 4.5kg packed.
- Electrical Supply 120-220V +105-20% 50/60Hz 15VA. Power supply is designed with high low-voltage tolerance to meet road show requirements.
- Options
- Security Panel 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.
- Output Balancing A separate output balancing unit is available to provide full transformer balanced and floating output sends to drive 600 ohm loads.
- Frequency contouring 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.
Features
- Combine selective de-essing sibilance control with compression or expansion.
- Control loudness in a way suited to AM/FM broadcast processing.
- Use the frequency-selective loudness control to enhance a frequency spectrum without additional equalisation.
- Preset LF loudness to maintain club safety limits.
- Obtain automatic level-controlled mixing of program sources for special effects.
