Connections

The PZS ™ 140RA features a rear panel connection scheme and includes
the following connection types:
• Microphone-Level Audio Input
• Line-Level Audio Input
• Summing RCA Line-Level Input
• Digital Remote Control
• Transformer-Coupled Loudspeaker Output
• Direct-Coupled Loudspeaker Output
• Transformer-Coupled Line Level Output
Except for the Digital Remote Control and RCA Line-Level Inputs, all
connections are placed on Euro connector blocks designed for easy
termination, service and maintenance. The unit ships with a matching
pluggable connector for each header block. The preferred method for
making audio connections consists of four steps as detailed in the steps
below. All terminations are identical except for the connection type and
the number of conductors per circuit. As with any electronic connection,
care should be taken to ensure the termination is solid. For a proper
termination, there should be no stray wire strands, kinks or nicks in the
wire jacket. As always, audio connections should be made with high
quality stranded wire. Input connections should be shielded.
STEP 1. Carefully strip the cable jacket and the conductor insulation.
The distance between the end of the jacket and the tips of the
conductors should be approximately .750". The strip length of the
conductor wire should be approximately .310" for proper termination
into the Euro connector.
STEP 2. Carefully insert each conductor into the opening of the Euro
connector. Take care to ensure that polarity is observed and that the
shield is properly twisted to make a solid connection. Ideally, the shield
should be isolated by installing heat shrink insulation.
STEP 3. While holding the cable so each conductor is firmly seated in
the connector, carefully tighten down each screw. While turning each
screw, look closely at the wire and make sure that the action of the
screw does not "push" the wire out of the connector. Verify the integrity
of your connection by gently pulling on each conductor to ensure that it
is terminated properly.
STEP 4. Take the completed wire/connector assembly and carefully
plug it into the matching connector header on the PZS 140RA's rear
panel. Take care that you are plugging the connector into the proper set
of pins on the header. There is no barrier between adjacent audio
channels, so it is possible to connect to pins of an adjacent channel. If
you are not careful, instead of connecting to Positive, Negative and
Shield, you may end up connecting Negative-Shield-Negative. Your
finished connector for a single input circuit should look like the
illustration to the right.

The line-level Euro inputs will also
accept un-balanced circuits. To
terminate an unbalanced source,
use the ground and positive
terminals. It is NOT necessary to
use a jumper to bridge the shield
and negative conductor.
