9.0 Input and Output Connections -
Rear Panel Facilities.
The input (See figure 9.1) is a 10K ohm balanced type on a standard 3 pin
female XLR which will accept levels up to +20dBv. The '+' or in-phase
connection is to pin 3 and the '-' or out-of-phase connection is to pin 2. There
is no connection to pin 1, and input cable shielding should be derived from
the equipment which is providing the input signal. When feeding the DPR-402
from unbalanced sources, connect the signal 'hot' to pin 3, and the signal
ground to pin 2.
The output connection (See figure 9.2) is a standard 3 pin male XLR. Output
impedance is less than 1 ohm, unbalanced, and full headroom is available
into any load 600 ohms or greater. The signal 'hot' is connected to pin 3, and
the ground to pin 2 and pin 1.
For rack mounted unbalanced audio systems, the case (power) ground can be
isolated from the signal by removing an internal wire link associated with
channel one output connector (See figure 9.3).
