3.4.1 Clock Termination Jumper J12 [terminated]

As would be appropriate for most applications, the default condition for the Send

Timing inputs on the data and clock connector is terminated (by means of a 150

ohm resistor). Certain situations may require that these inputs be unterminated

(e.g., multiple inputs driven from a single output). This can easily be accomplished

by moving jumper J12 to the unterminated position (move jumper towards the

front of unit).

3.4.2 Analog Audio Input Termination J13/J14 [10k ohms]

If you are using equipment designed to drive loads with a high input impedance,

leave the jumpers in the DP503 in the 10k position. If you are driving the unit with

equipment whose output requires a 600 ohm load, these jumpers should be moved

to the 600 ohm position (move jumpers towards the rear of the unit).

3.4.3 Signal Ground-to-Chassis Link J15 [open]

It is normal practice to connect signal ground to power line ground for many

reasons, including safety. In most systems, minimum induced hum is obtained

when this connection is made at one and only one piece of equipment in the audio

chain. To minimize the addition of circulating ground currents in a particular

installation, the default setting for this jumper link is open. Note that there is

always a 1 kohm resistor across the link so that the audio ground is never totally

isolated from the chassis ground. To connect audio ground directly to chassis

ground in the DP503, move jumper J15 to the closed position (move jumper

towards the rear of the unit).

CAUTION: The chassis is always connected to the ground pin of the power line cord. For safety

reasons this ground wire MUST NEVER be disconnected.

3.5 Configuring the Rear Panel DIP Switch S101

The Model DP503 includes certain user-selectable options that are configured by

means of a rear panel DIP switch, S101. Some of them should be configured prior to

first use. Others can be changed as operational needs dictate (See also Section 5).

The default settings (delivered from the factory) are shown in brackets in the table

below. Before installing the unit, be sure to verify that the switch positions are in

their desired positions. Explanations follow below.

Note: Unlike the DP524 decoder unit, on the DP503, the “off” position of the switch is in the UP position.
