Speaker placement
e P777 allows connection of up to seven
loudspeakers. All speakers, with the exception of the
subwoofer, should be arranged around your normal
viewing/listening position (see diagram). e subwoofer
can be placed almost anywhere and we recommend
experimenting with it in various positions to obtain the
best result.
e closer you place a speaker to intersecting room
surfaces (corners, wall and ceiling, wall and oor),
the stronger the bass output. is can help bass-shy
speakers, but it can also add too much bass. Again, just
moving a speaker a few inches can oen make a big
dierence in sound.
Position your front le (L) and right (R) speakers
to achieve a good stereo image for normal musical
reproduction. If they are placed too close together there
will be a lack of spaciousness. Alternatively if they are
placed too far apart the stereo image will appear to have
a hole in the middle and will be presented in two
halves.
e centre speaker (C) allows for a more
realistic reproduction of dialogue and
centre sounds as well as wider and
better imaging for stereo eects
and background sounds for
home cinema use. Do not
compromise on the quality
of your centre speaker as it
carries all the dialogue for a
home cinema system.

Notes on making speaker
connections
< Do not make any connections to any amplier
while it is switched on. We recommend that
your amplier is completely disconnected
from the mains supply before starting.
< Before switching your amplier on for the
rst time aer connecting to speakers, please
check all connections thoroughly. Ensure
that bare wires or cables are not touching
each other or the amplier’s chassis (which
could cause short circuits), and that you
have connected positive (+) to positive and
negative (–) to negative. Be sure to check the
wiring for both the amplier and the speaker.
< Aer making connections: switch the
amplier on, with the pre-amplier volume
set to a low setting. Select a source signal, then
gradually increase the volume to the required
listening level.
< If you are unsure as to how your system
should be connected, or need advice on
bi-wiring or bi-amping, please contact your
Arcam dealer who will be happy to help you.
Speaker wiring options
Single wiring
Single wiring is the conventional wiring method of
running a single cable per channel between the amplier
and the speaker; this is the easiest technique.
Bi-wiring
Bi-wiring is running two separate cables between the
amplier and each speaker, with one cable carrying
the low-frequency information, the other the higher-
frequency signals.
Bi-wiring can improve the sound of your system because
the separation of high- and low-frequency signal
currents into dierent speaker cables avoids distortions
caused by the dierent currents interacting with one-
another within a single cable, as occurs in single-wired
systems.
e P777 is designed to allow easy bi-wiring, but you
will need to connect to loudspeakers that provide
separate terminals for the two cables. Each speaker
must have two pairs of terminals; one pair labelled
HF
or ‘High Frequency’, the other pair labelled LF or ‘Low
Frequency’.
Bi-amping
Bi-amping is the separation of the amplication of
low- and high-frequency signals over two ampliers.
Bi-amping requires the use of two ampliers per
channel.
e surround le (SL) and right (SR) speakers
reproduce the ambient sound and eects present in a
multichannel home cinema system.
e surround back le (SBL) and surround back right
(SBR) speakers are used to add extra depth, a more
spacious ambience and sound localisation.
A subwoofer (SW) will greatly improve the bass
performance from your system. is is useful for
reproducing special cinema eects, especially where
a dedicated LFE (Low-Frequency Eects) channel is
available, as with Dolby Digital or DTS Digital Surround
encoded discs.
