Instructions for Use. Page 6 of 9
REMOTE CONTROL
The A300 features Infra Red remote con-
trol of volume, input selection and mute
functions via the supplied remote control
handset. The Infra Red receiver is the
small red lens marked I.R.Receiver. situat-
ed on the front panel. It is important to
ensure that when operating the remote con-
trol, the line-of-sight from the remote to
the infra red receiver is not obstructed.
Pressing the volume up or down buttons on
the remote handset will advance the
motorised volume control in the desired
direction.
Input selection can also be controlled with
the remote handset.
The mute button on the remote handset
mutes the output. To show the amplifier is
muted the red LED in the volume control
goes out. Press the mute button again to
switch the mute off, the red led will light
again.
PREAMP OUTPUT
The A300 has a permanently active pre-
amp output situated on the back panel.
This provides extra flexibility for use in
multi-room or surround-sound systems etc.
This signal comes from the A300's internal
preamp and its output level is thus con-
trolled by the front panel volume control.
This output allows easy upgrading by pas-
sive bi-amping with a pair of X-A50s or
X-A200s.
To bi-amp (which requires bi-wireable
speakers) an extra pair of X-ponent ampli-
fiers is attached to this permanent preamp
output.
The A300's built in power amps can then
for instance drive the left and right channel
tweeters whilst the X-A50s or X-A200s
drive the left and right channel bass units.
Passive bi-amping in this way can give
noticeable gains in clarity, imaging and
bass weight.
