The optional digital output module allows simultaneous output of 24-bit AES/EBU and ADAT Optical. Eight remote controllable, Jensen transformer-coupled microphone preamps in a 2U rack-mount chassis. Limiter in the front end of the preamp limits the output level of the microphone by as much as 20dB. This allows the engineer to get maximum noise performance and also allows maximum resolution for an analog to digital converter, all without worrying about crashing the preamp. A 26dB pad allows a preamp to be run as a unity gain buffer stage.
This allows the line level output of a wireless mic receiver to be fed into the preamp. Output level trims of up to 24dB. Once the maximum input level of the device following the 1788A is defined, the output level of can be trimmed to that exact level. The input gain of the 1788A is then adjusted to achieve optimum performance.In addition to the 24db of output adjustment, each output may be muted. Two separately trimmable, buffered analog outputs. The main output on XLR is transformerless servo-balanced and the second output is transformerless balanced on a DB-25 multi-pin connector. This allows two separate inputs to be fed at optimal levels from an optimized microphone preamp. Includes a 700Hz test tone at two different levels which can be bussed to any selected preamp channel. The two levels are at 0dBfs (maximum output level) and -20dBfs. The test tone at 0dBfs allows easy set up for finding maximum peak input into following stages. The -20dBfs tone is useful for digital systems which use a -20dB reference tone. LED indicators for the status of each function for each channel. A twelve-segment LED meter displays headroom. Two eight segment LEDs show input gain or maximum output level on either of the two analog outputs. All indicators and metering can be monitored at the remote location. Any channel can be selected and the output level adjusted. Power cords are not included unless otherwise specified. You agree to all terms and conditions.
