Aphex 1788A Remote Controlled Mic Preamp
The unit provides 8 balanced Jensen® transformer-coupled microphone preamplifier inputs, offering audiophile sound quality far better than the mic preamps found in most mixing consoles. It also provides two separately trimmable analog outputs for each channel. The optional digital output module allows simultaneous output of 24 bit AES/EBU, T/DIF® and ADAT® Optical.
These A/D converters are selectable up to 96 kHz and are Aphex proprietary "Drift Stabilized" (patented), eliminating the need for high pass filtering in the digital domain. Because the inputs to the A/D converters are trimmed exactly to the outputs of the preamp, digital resolution can be maximized without fear of crashing. This makes the 1788 the perfect front end to any DAW, fiber system, or digital console.
This microphone preamp and its model 1788RC remote controller form a complete microphone preamp system with 5 outputs (3 digital and 2 analog) available simultaneously.
