The Aphex Model 1788A is a premium 8-channel remote controlled microphone preamplifier with sophisticated features. Remote control means the preamps can be located anywhere they are needed for optimum performance. By locating 1788A’s just off-stage, near the microphones for example, many difficulties can easily be overcome such as long mic lines picking up noise and RF interference; capacitance of long mic lines degrading the high end response; mic splitters dumping multiple loads onto the mic knocking down output level and making mics sound dull and lifeless.

Controls on the front are graphically divided into five separate blocks: Local, Control, Digital, Monitor and Test.

The Local Block includes the individual meters and function lights for all eight channels, and a single set of assignable function control buttons plus a multipurpose ADJUST knob.

The Control Block manages port and NET parameters.

The Digital Block manages the digital audio parameters when the Digital Option is installed.

The Monitor Block puts the selected channel’s sound up on headphones.

The Test Block is used to calibrate system levels. 

MicLim™, our patented “microphone output limiter”, limits in front of the preamplifier to prevent overloading the front end. LeNA™, our patented digitally controlled low noise amplifier, allows glitchless and noiseless local and remote control over gain. 

The Model 1788A has three analog signal groups:

1. Eight Balanced MIC Inputs on XLR

2. Eight Servo-Balanced MAIN Line Outputs on XLR

3. Eight Active Balanced AUX Line Outputs on one 25 Pin D-Sub following Tascam pinout.
