Section 1: Introduction- Technical Overview
This portion of the introduction provides some of the technical details of the
Audio Input Path
There are two audio channels each with two input connectors, a balanced
Audio Output Path
The first stage the audio passes through is an inverting gain stage. The second stage is a second order Butterworth low pass filter that removes high frequency sampling artifacts. The signal is then sent out of the
Power Supply
No external power supply is needed for use with the CX, DCA and PL2
DCA, and PL2 amps made prior to August 1999 DO NOT provide adequate power supply voltage to the module, requiring the use of the same type of external DC supply as used with Powerlight amplifiers. The amps in question will have a serial number PRIOR to 0899XXXXX, where the first four digits of the serial number are the MMYY datecode. Again, the modules WILL work with these amps just fine, but will require the use of our external power supply. External power is not required for all other
