dbx 208 / 209 RMS Detector Module for 160, 161 VU, NR Cards Tested, Warranty. DF

Note: we've had to increase the price of this item due to lack of availability of working used modules, and the large amount of tech labor involved in testing and repairing them. If you need a 208/208 for a DIY project you might consider using a dbx 207 RMS Detector instead. The 207 has a different form factor and pinout than the 208/207 but they are fully compatible and much less expensive. dbx 207's can be found on our evay store, ebay item #321138041146

Original dbx 208 / 209 RMS Detector module, carefully tested and fully guaranteed. The leads are about 1/4 long. This module was used in the dbx 160 and 161 VU compressors, and various 3rd party products over the years. Applications included many of the dbx 900 series modules and dbx compressors, SSL, MCI, Harrison and Sony consoles, etc. A wiring diagram showing a 208 module and VCA will be included with each item. (Note: the dbx 208 is interchangeable with the dbx 209, which is nearly identical.)

Some of these are 208's, some are 209's. The difference is negligible and specs are the same. Some cases are silver, some are black, general appearance varies.

The model 208 is actually an RMS Detector and a log-linear converter in one package. The input terminal is a current input and requires an input resistor. It is compatible with the dbx model 7 and 202 VCA's, which are both available through our store. The model 7 is the original VCA, that was used in the original dbx 160 VU series of limiters. The 202 is a later, more stable version that was used in many dbx, SSL, and other products.

Specs are:
Supply voltage: +/- 15 VDC
DC output constant: -6mv per 1 db increase at input
Response to small increment on a steady signal: 35 millisecond time constant
Response rate on removal of input signal: 120 db per second
Increment rate for large increase in signal: 80 db per millisecond.
