INSTALLATION
LOCATION
To avoid addition of jitter (timing variations) to the output clock signals, which could cause noise and distortion
or loss of synchronization in the recovered audio, avoid locating the DDA in close proximity to a high energy,
high frequency switching type power supply or a power amplifier that utilizes a switching supply. If possible, do
not power both devices from the same AC power line.
POWER
If it is necessary to convert a unit wired for 115VAC to 230VAC operation, unplug the unit from the power
source, remove the cover mounting screws and locate the jumpers next to the power transformer. Clip the
jumpers 1-2 and 3-4 (don’t unsolder), jumper from 2-3 carefully soldering together the free ends of 2-3
previously clipped. This procedure is recommended to avoid soldering damage to the multi-layer PC board.
WIRING
XLR inputs require special controlled impedance, 110 ohm, low loss, foil shielded, twisted pair cables. Standard
audio cable is not recommended except for runs of only a few feet. Belden and most other cable manufacturers
offer special digital audio cabling for this application. Keep cable length as short as possible.
