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.
4. 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
Loudspeaker Ouput Terimals (+Positive or
- Negative)connections together, ground
them or connect with another amplifier.

Direct Current is detected at the Output Terminals.
• Power Supply
The a340 Power Amplifier has several regulated
power supplies, each one extremely stable to ensure
noise free operation even though the power line varies.
• Trigger Input and Output Connections
The Trigger Input and Output connection provides
convenient Turn-On/Off of additional Power Ampli-
fiers and/or Source Components.
• Gold Plated Connectors
The Input and Output Connector Contacts are gold
plated for superior corrosion resistance and high elec-
trical conductivity.
• Custom Binding Posts
Patented gold plated output terminals deliver high
current output. They accept large diameter wire and
spade lugs. Banana plugs may also be used only in the
United States and Canada.
• LED Front Panel Indicator
A long life Light Emitting Diodes (LED) are used to
indicate the operational status of the a315.
• Die Cast Aluminium Chassis

Auto Off
The a340 incorporates a Power Save Feature to
automatically switch power Off to the Power Ampli-
fier approximately 30 minutes after there has been an
absence of an audio input signal.
Note: If the Power Save Feature has activated and
switched the a340 Off, the Power Save Fea-
ture can be reset by momentarily pressing the
STANDBY/ON Push-button.
When there is a Trigger Control Connection be-
tween the a340 and a Preamplifier or Source Device,
the Power Save Feature in the a340 is bypassed.
With the a340 connected (via Trigger Control) to
a Preamplifier (Source Device) with the Power Save
Feature and the feature is active, the a340 will switch
Off with the Preamplifier (Source Device) after a
period of inactivity.
There may be times when it would be desirable to
bypass the Power Save Feature, which by default is ac-
tive. This can be implemented by placing the “AUTO
OFF” Switch, located on the a340 Rear Panel, in the
DIS (Disable) position. Refer to figure 8.

Packing Instructions
In the event it is necessary to repack the equipment for
shipment, the equipment must be packed exactly as
shown below. It is very important to ensure the proper
equipment location between the bottom and top foam
pads. Failure to do this will result in shipping damage.
Use the original shipping carton and interior parts
only if they are all in good serviceable condition. If
a shipping carton or any of the interior part(s) are
needed, please call or write Customer Service Depart-
ment of Wadia. Refer to page 4. Please see the Part
