Expensive components start to die at internal temperatures above 70°C (158°F). We recommend that
you maintain rack temperatures below 50°C (122°F) to prevent excessive internal temperature buildup.
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 for external clock sources 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. BNC connectors
use 75-ohm coax (RG59). Select a cable for losses less than 20dB at 12MHz (for data rates up to 96kHz) at
the maximum distance you require. Keep cable length as short as possible, especially when working with
Super Word clock rates.
