 PRODUCT INFO
The Aphex Model 188 houses eight high-quality mic preamps in a single 1U rackmountable chassis. Like the company’s popular 1788A, all settings of the Model 188 may be remote controlled via Ethernet or MIDI, using Aphex’ 1788A-RC hardware remote or the 1788SW control software (PC and Mac), or via Pro Tools®.

The Model 188 has one analog output as well as two ADAT Optical outputs, each carrying eight channels of audio. The two outputs may be used for redundant operation, or to combine for higher sampling rates (SMUX).

Unlike the 1788A, the Model 188 does not have the extensive onboard metering, nor does it include Aphex’ exclusive MicLim™ technology which limits the signal at the mic input. However, the 188’s 1U rackmount chassis makes it ideal for mobile systems with space limitations, and it consumes less power than the 1788A.
