DA824—Owner’s Manual
1 Introduction
Welcome
Thank you for choosing the Yamaha DA824 DA Converter.
The DA824 is a high-performance 8-channel digital-to-analog converter, with 24-bit
linear digital-to-analog converters and 128-times oversampling providing a typical
dynamic range of 110 dB. Optional mini YGDAI (Yamaha General Digital Audio Inter-
face) cards offer a variety of digital input interfaces, with support for all the popular dig-
ital audio interconnect formats, including AES/EBU, ADAT, and Tascam TDIF-1.
Installation
The DA824 can be used freestanding on a stable surface, somewhere that complies with
the important information at the beginning of this manual, or mounted in a rack.
When mounting the DA824 in a rack, leave adequate ventilation space around the
DA824 (at least 10 cm of free space behind). If the DA824 is mounted in a portable rack
case, keep the rear of the case open when using the DA824, so as not to obstruct the flow
of air from the air vents. Do not mount the DA824 next to equipment that produces a
lot of heat, such as a power amplifier.
Setting the Maximum Output Level
Inside the DA824 are eight output-level switches for presetting the maximum output
level of each analog output. Maximum output levels settings are: +24 dB, +18 dB,
+15 dB, and +4 dBV. See you Yamaha dealer for more information.
Connecting the Power Cord
Connect the power-cord plug to a suitable AC wall outlet, one that conforms to the
power supply requirements stated on the DA824 rear panel.
Turning On the Power
To prevent audible thumps and clicks, turn on your audio equipment in
the following order (reverse this order when turning off your equip-
ment)—sound sources, mixer or recorder (e.g., 02R, DME32, D24, etc.),
DA824, power amplifiers.
