POWER SUPPLY
Your DA 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 suppressor is placed across the power
transformer secondary.
INSTALLATION
MOUNTING
Your DA may be desk mounted on its non-slip suction cup, or 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 DA 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
DA2008 rear panel. Run the strap to within a few inches of the chassis and jump
to the chassis ground with shield braid.
Audio inputs and outputs should be connected using the rear panel labels as a
guide. Hi outputs are all in phase with each other and in phase with the Hi 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 those tiny barrier strip screws.
The fanning strips are Kulka part number 649A22 and extras are available from
our parts and accessories department. For convenience, the fanning strips may
be easily cut into shorter input or output sections.
To allow maximum flexibility in grounding in high RF environments, the circuit
grounds are isolated from case ground. For normal operations, add a ground
jumper from the barrier strip ground terminal closet to the inputs to the chassis
ground screw.
