Making its AES debut and currently available at an MSRP of $2,200, the eight-channel AD8HR provides the same head amplifier circuitry inherited from the Yamaha PM5000 mixing console, and by supporting sampling rates of up to 96kHz for smooth integration with digital mixers. The 1U AD8HR contains a full range of analog and digital interfaces, plus all the functions required for effective and flexible live mixing. A user-friendly front panel provides quick operation and instant recognition in live situations, while each channel contains integrated high-pass filters and phantom power supplies.
"Since head amps play a vital role in the sound quality of any A-to-D converter, Yamaha conducted strict and impartial listening tests with top audio professionals in order to perfect the design of the AD8HR," states Larry Italia, general manager, Yamaha Commercial Audio. "By using the same circuitry found in the Yamaha PM5000, the AD8HR provides clean, uncolored sound quality for any live, installed, recording or post application."
A Head Amp Remote Control function will operate channel phantom power and high-pass filter cut-off frequencies by remote control, making it possible for the AD8HR to be used as a stage box. This function also allows the unit's mic preamp to be remotely controlled in 1dB steps from digital mixing consoles such as the Yamaha DM2000 and DM1000 (with Version 2 software upgrades). Up to 255 AD8HRs can be daisy-chained together using a standard nine-pin RS422 and a digital connection via AES/EBU.
"The advantage of using AES/EBU cable for connection between a digital board and the AD8HR is that it reduces the need for analog wiring, and keeps signal in the digital domain," states Marc Lopez, product manager, Yamaha Commercial Audio. "By using the AD8HR's AES/EBU connections to full advantage, signal can be split into two lines for parallel house/monitor output, or for remote recording applications."
Rear panel connections include eight XLR inputs, BNC-type input/output connectors for Word Clock and two D-SUB25 pin AES/EBU digital output terminals. Remote control can be accessed by using a switchable PC/RS422 nine-pin terminal.
