Dynamic Range Enhancer
The DBX 117 can re-expand the limited dynamics of tapes, records and FM broadcasts and bring your music back towards it's original dynamics.
The 117 is easily connected to your receiver or integrated amplifier/preampliifer.
Compression & expansion: continuous from 1.4 compression slope (14 dB output change/20 dB input change) to 2.0 expansion slope (20 dB output change/10 dB input change)
Dynamic range: 120dB input or output
Input noise: -110 dBm typical, -100 dBm maximum
Input level: maximum input signal in excess of 30 Volts RMS
Input impedance: 50K ohms
Output level: maximum output 10 Volts RMS open circuit; +17 dBm into 600 ohms
Output impedance: 500 ohms
Distortion: 0.5% maximum @20 Hz, 0.2% typical above 50 Hz for complete cycle of compression and expansion; 1.2% @20 Hz for 2:1 expansion; .05% typical @ 1 KHz and above for any setting of controls (3 Volts RMS or less input or output.)
Frequency response: +0, -1dB 20 Hz to 20 KHz
Attack time: 50 dB/m Sec maximum initial attack rate @1.4 expansion. 12 mSec to 65% of final value @ any setting of compression or expansion. Adjusted to be within integrating time of human ear within the constraints of reasonable low frequency distortion.
Release (decay) time: constant rate 140 dB/sec (norm) or 50 dB/sec (slow) @ 1.4 expansion
Level match control: unity gain point may be varied from 100 mV to 1 Volt
Power consumption: 115 VAC 50-60 Hz 2 Watts
Dimensions: 3 3/4 x 5 1/4 x 9 inches
Weight: 4.5 lbs
