Yamaha AD8HR High Quality 8-Channel Mic Preamp/Digital Audio Converter

Analog-to-Digital converter, 1U, XLR/BNC

8-channel mic pre/AD converter combining unparalleled sound quality with a host of innovative functions

It goes without saying that head amplifiers play a vital role in determining the sound quality of any analog-to-digital converter, and for this reason, Yamaha selected the circuitry used in their PM5000 – the state-of-the-art analog mixing console – for the AD8HR’s microphone pre-amp design. In order to achieve immaculate sound reproduction through 96kHz processing, the finest available parts have been carefully selected.

The AD8HR’s mic pre-amp can be remotely controlled in steps of 1 dB from certain digital mixing consoles, and with a high pass filter and a phantom power supply integrated into each channel, both the filter and phantom power can be turned on and off by remote control, as can the filter’s cut-off frequency. This Head Amp Remote Control function makes it possible for the AD8HR to be used as a stage box. In addition to the many advantages that this offers, digital connection of the AD8HR and DM2000 using an AES/EBU cable reduces the requirements for analog wiring to the bare minimum.

Packaged in a space-saving 1U case, the AD8HR boasts a full range of analog and digital interfaces. And with its integrated high-pass filters and phantom power supplies, this AD converter features all of the functions required for effective and flexible live mixing.

Each of the rear panel’s eight inputs features an XLR connector with a latch lock; furthermore, a pair of D-SUB25 pin AES/EBU digital output terminals is fitted as standard and with BNC terminals provided for word clock input and output, the AD8HR covers every base in terms of digital connection.
