and the sleeve connection (white) is wired to the LO output. To use a standard tip ring
sleeve patchcord output, rewire the jack terminals by removing the blue wire from the
ring terminal moving the white wire to the ring connection (and grounding the sleeve
terminal to the top shield foil of the P.C. board.)
POWER SUPPLY
Your power supply incorporates a couple of unique regulating devices called zener
diodes. In contrast to most fancy IC regulators, these devices will live through most line
transients and simultaneously protect your expensive circuitry. As further insurance, a
varistor suppresser is placed across the power transformer secondary.
INSTALLATION
MOUNTING
Your DA1000 may be desk mounted on its non-slip suction cup.
Rack mount system 21075-501 mounts two units in one rack.
WIRING
There are three wire grounded plugs. The third wire ground can cause a ground loop with
your station ground. If you are sure your station ground will provide adequate protection
to personnel in case of an AC line short to chassis, a 3 to 2 AC adapter can be used to
isolate the power line ground. We recommend that the adapter be removed and the power
line ground reconnected prior to any service work requiring removal of the station ground
from the chassis.
The four inch silver bearing copper strap, which you are, of course, using for your station
ground is not going to fit around the #6 chassis ground screw on the rear panel. Run the
strap to within a few inches of the chassis jump to the chassis ground with shield braid.
Audio inputs and outputs should be connected using the rear panel labels as a guide. Hl
outputs are all in phase with each other and in phase with the Hl inputs. Fanning strips are
provided so that our ears won't be burning in the middle of the night while you are trying
to wrap wires around tiny barrier strip screws. The fanning strips are Kulka part number
649A22 and extras are available from our Parts and Accessories Department.
To allow maximum flexibility in grounding in high RF environments, the circuit grounds
are isolated from case ground. For normal operation, add a ground jumper from the
barrier strip ground terminal closest to the inputs to the chassis ground screw.
CAUTION: Balanced differential output has active drivers for both HI and LO output
terminals. DO NOT GROUND either HI or LO terminals. To drive an unbalanced (one
side grounded) load, connect it between HI and GND terminals and let the LO terminal
float. Two separate 600 ohm unbalanced loads can be driven from each output without
