Output Terminals
When connecting the Loudspeaker Hookup Cables
to the a102 Power Amplifier Output Terminals please
follow the steps below:
1. Rotate the top of the Output Terminal Post coun-
terclockwise until an opening
appears. Refer to figures A and
B.
2. Insert the Loudspeaker hookup
cable into the Output Terminal
Post opening or the cable spade
lug around the center post of
the Output Terminal. Refer to
figure C.
3. Rotate the top of the Output
Terminal Post clockwise until
it is finger tight. Refer to figure
D.
4. Place the supplied Wadia
Wrench over the top of the
Output Terminal and rotate it
one quarter of a turn (90°) to
secure the Loudspeaker Cable
Connection. Do not over
tighten. Refer to figure E.
How to Connect
Caution: Do not connect the AC Power Cord to the a102
Rear Panel until after the Loudspeaker Con-
nections are made. Failure to observe this could
result in Electric Shock.
This Wadia a102 Power Amplifier is designed for
Loudspeakers with an impedance of 4 ohms or 8
ohms. Connect a single Loudspeaker only to the Right
and Left Output Terminals.
The connection instructions below, together with
the illustration on the next page, is an example of
10
connecting typical Loudspeakers to the a102. Your
Loudspeakers may vary from this, however the actual
connections would be made in a similar manner.
When connecting Loudspeakers to the a102 it is
very important to use cables of adequate size, so there
is little to no power loss in the cables. The size is
specified in Gauge Numbers or AWG (American Wire
Gauge). The smaller the Gauge number, the larger the
wire size:

1. Prepare the Loudspeaker Hookup Cable for attach-
ment to the a102 Power Amplifier:

Bare wire cable ends:
Carefully remove sufficient insulation from the
cable ends, refer to figures 2, 3 & 4. If the cable
is stranded, carefully twist the strands together
as tightly as possible.

into the banana plugs and secure the
connections. Refer to figure F.
3. Rotate the top of the Output Terminal
Post clockwise until it is finger tight.
Refer to figure G. Then using the Wadia
Wrench, rotate the top of the Output
Terminal one quarter of a turn (90°).
Do not over tighten. Refer to figure E.
4. Referring to figure H, connect the
Loudspeaker hookup cables
with banana plugs into the hole

and Positive Output Terminals,
being careful to observe the
correct polarities.
Refer to "General Information" Note 3 on page 4 for
additional information.
WARNING: Loudspeaker terminals are hazardous
live and present a risk of electric shock.
For additional instruction on mak-
ing Loudspeaker Connections contact
your Wadia Dealer or Wadia Technical
Support.
5. Connect the a102 Power Cord to an active AC
outlet.

6. Connect the Loudspeaker hookup cables to the
a102 Negative Output Terminal and Positive
Output Terminal, being careful to observe the cor-
rect polarities. Insert the spade lug connector or
prepared section of the cable end into the terminal
side access hole, and tighten the terminal cap until
the cable is firmly clamped into the terminals so
the lugs or wire cannot slip out. Refer to figures 5
and 6.
