1. For additional connection information, refer to the
owner’s manual(s) for any component(s) connected
to the Wadia a315.
2. The Wadia a315 mutes the speaker output for ap-
proximately two seconds when first turned on.
3. For the best performance and safety it is important
to always match the impedance of the Loudspeaker
to the Wadia a315 Power Amplifier Connections (4
or 8 ohms). Refer to “How to Connect” pages 8 thru
11.
Note: The impedance of a Loudspeaker actually var-
ies as the Loudspeaker reproduces different
frequencies. As a result, the nominal impedance
rating of the Loudspeaker (usually measured at
a midrange frequency) might not always agree
with the impedance of the Loudspeaker at low
frequencies where the greatest amount of power
is required. Contact the Loudspeaker Manufac-
turer for additional information about the actual
impedance of the Loudspeaker before connecting
it to the Wadia a315.

In the event the Wadia a315 over heats, due to
improper ventilation and/or high ambient tempera-
ture, the protection circuits will activate. The Front
Panel Standby/ON LED will start flashing. When
the Wadia a315 has returned to a safe operating
temperature, normal operation will resume.
5. The protection circuits will also activate when
improper connections are made to the Loudpeaker
Output Terminals.
Caution: The Loudspeaker Output - Negative
Terminal Connections are not connected to
chassis ground. Do not combine any of the
Loudspeaker Ouput Terimals ( + Positive or
- Negative) connections together, ground
them or connect with another amplifier.
General Information and Connector Information
Connector and Cable Information
XLR Connectors
Below is the Pin configuration for the XLR Balanced
Input Connectors on the a315. Refer to the diagram for
connections:
PIN 1: Shield/Ground
PIN 2: + Output
PIN 3: - Output
Trigger Control Connector
The Wadia a315 Trigger In receives an On/Off signal
from +5 to +12 volts. The Trig-
ger Out will in turn provide a
+12 volt Output Signal with a
total current up to 50mA.
Output Terminal Connector
When cables with spade lugs are used
for Loudspeaker Connection, the spade
lugs need an opening of at least 3/10 inch
(7.6mm).
