Anthem Amp 2 Owner's Manual - page 6
INSERTION O F THE TUBES
1. Using the screwdriver supplied, remove the cover of the
Amp 2. For your convenience, only two of the screws are
installed at the factory.
2. When handling the tubes, it is recommended that the
cotton gloves provided be worn to prevent skin oils from
depositing on the glass surface and possibly causing the
tube to become prematurely “gassy”, thereby shortening
the tube’s useful operating life.
3. Noting the location of the tube sockets in the top view
photo, inspect the tubes for corresponding labels and
markings. Once locations are mapped, take a tube and
inspect the pins, noting the larger space between two of
the pins (see Figure 2). This space will match with the socket.
Insert each tube into the appropriate tube socket, making
sure all pins and pin holes are aligned. Do not force the
tubes into the sockets. “Rock” the tubes gently while pushing
slowly until each tube is firmly seated.

Before plugging in the Amp 2, check to see that the unit is
configured for the correct AC line voltage for country of use.
The operating AC line voltage is indicated on the side of the
shipping box. If the Amp 2 is set incorrectly for the country
in which it is to be operated, contact the dealer or distributor
in your area. If the unit is configured properly, continue with
operation.
Connect the Detachable Power Cord to the Amp 2 AC
Power Cord Socket (C) (see Figure 4). Plug your Amp 2 into
the AC power source.
Connect loudspeakers to the appropriate post as described
in the connection section of this manual.
The two remaining connections are made with co-axial
cable and RCA connectors to a suitable Preamplifier such
as the Anthem Pre 2L.
Connect the pre amp to the Amp 2 Inputs (E); left channel
to left channel and right channel to right channel.
The Amp 2 is now ready for operation. Power the Amp 2 by
placing the On-Off button (B) in the ON position. The tubes
will take approximately 30 seconds to warm up and then
the Amp 2 is functional.
It is recommended that you shut OFF the main power via
the Power Switch (B) when not listening.
Note the larger space
between two of the pins and
holes for proper alignment
of tube and socket.

This Amp 2 provides convenient means to operate the
amplifier in Bridged Mono mode. This is achieved via a rear
panel mounted switch and minor reconfiguration of your
speaker connections.
When operated in the Bridged Mono configuration, the
amplifier is capable of providing up to 600 watts into a 8
ohm monophonic load.
For Bridged Mono operation, place the Stereo/Bridged
Mono switch in the bridged mono position. Connect the
signal source to the Left (Mono) input jack. Connect the
SPEAKER + terminal T O the Amp 2’s LEFT + output binding
p o s t . Connect the SPEAKER – terminal TO the Amp 2’s
RIGHT + output binding post. Refer to fig. 4.
Next, a single conductor of speaker wire, preferably of the
same wire type as the speaker cable used, is conected
from the Amp 2’s LEFT – binding post to the RIGHT –
binding post. No other connections are made to the black
LEFT and RIGHT – binding posts.
