APHEX - 188 v2.01 Microphone preamplifier - Multiple models

Aphex 188A

Aphex presents the new 188, an eight-channel microphone preamplifier remotely controllable via Ethernet or MIDI, through the same devices that can control the model 1788A, namely from the 1788A‑RC controller or from the software (PC or Mac) 1788A‑SW or, using the optional interface model 5200, from a control surface by Avid or a Yamaha digital mixer. The 188 features eight preamps, each with transformer‑isolated input, polarity selector and a selectable 80 Hz high‑pass filter. The preamps offer 26 dB of fixed gain and 39 dB variable gain, for a total of 65 dB, and each input also includes a ‑26 dB attenuator. The channel analog outputs are available on a D‑sub 25 connector, while the digital ADAT outputs are available on two TOSLINK connectors, configurable as redundant or SMUX to allow operation at sample rates up to 96 kHz. The 188’s internal clock can operate at 44.1, 48, 88.2 or 96 kHz and a word clock output is available. It also accepts external clock inputs operating from 44.1 to 96 kHz.
