AD Converter with Remote Preamplier
Remotely controllable 8-channel AD converter and preamplier with
96 kHz processing.
• Microphone preamplifier technology inherited from the PM5000 analog live sound console for unsurpassed sound quality.
• Microphone preamplifier gain can be remotely controlled in steps of 1 dB from compatible Yamaha digital mixing consoles.
• High-pass filter with remotely controllable cutoff frequency on each channel.
• Remotely switchable phantom power supply.
• Up to 255 AD8HRs can be daisy-chained for massive input capacity.
• AES/EBU digital connection to digital mixing console minimizes the need for analog cabling.
• Eight XLR connectors and D-Sub AES/EBU terminals in a compact 1U design.
• Dual output connectors enable 2 x 8-channel digital audio output in the AES/EBU format.
• Remote control can be implemented via RS422 or switchable PC/RS422 nine-pin terminals.

*1 Total harmonic distortion is measured with a 18dB/Oct filter @80kHz.
*2 Hum & noise level is measured with a 6dB/oct filter @12.7kHz; equivalent to 20kHz filter with
infinite dB/Oct attenuation.
* Crosstalk is measured with a 30dB/octave filter @22kHz.
