6. When discarding the unit, comply with local rules 

or regulations. Batteries should never be 

thrown away or incinerated but disposed 

of in accordance with the local regulations 

concerning battery disposal.

7. For additional information on the Wadia 

a340 and other Wadia Products please visit the 

Wadia Web Site at www.wadia.com.

1. For additional connection information, refer to the 

owner’s manual(s) for any component(s) connected 

to the Wadia a340.

2. The Wadia a340 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 a340 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 a340.

In the event the Wadia a340 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 a340 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

General Information and Connector Information

Connector and Cable Information

XLR Connectors

Below is the Pin configuration for the XLR Balanced 

Input Connectors on the a340. Refer to the diagram 

for connections:

  PIN 1: Shield/Ground

  PIN 2: + Output

  PIN 3: - Output

Trigger Control Connector

The Wadia a340 Trigger Input receives an On/Off 

signal from +5 to +12 volts. 

The Trigger Output 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).
