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.

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.
