Switching on
The
POWER
button switches the unit on and off.
The power light (next to the ‘POWER / STANDBY’
text) indicates the state of the amplifier: it changes from
red to orange then green if mains power is connected
and the unit is switched on.
If the unit is left unused for an extended period of time
it will go into standby to reduce power consumption.
Press
AUX
and
BALANCE
to adjust the time of this feature.
Display
The
DISPLAY
button (or
DISP
on the remote control)
changes the display brightness between ‘on’, ‘dimmed’
and ‘off’. If the A49/C49 is powered off with the display
brightness set to ‘off’, the display resumes to ‘dimmed’
when the unit is powered on again.

Selecting an audio source
Audio sources may be selected from the front panel
buttons (
PHONO, Aux, CD, TUNER, SAT, BD, PVR, AV
), or the
remote control (
PHONO, AUX, CD, TUN, SAT, BD, PVR, AV
).
In each case, the source is selected from the input
sockets with the corresponding name.
Audio inputs
Although the inputs are labelled for specific devices, all
have the same characteristics and each may be used with
any line-level product. The exception is the
PHONO (MM)
input (see pages 20-21 for the specification).
AUX (XLR)
Intended for the balanced analogue outputs from a
source, for example the Arcam D33. The balanced
inputs can also be assigned to any other input key on
the remote. Either use the
MENU
button on the remote to
access the setup menu, or press the front panel
BD
and
BALANCE
buttons simultaneously and use the control
knob to change the setting. The front panel display shows
(e.g.)
XLR CD
. In this example, when the
CD
button on
the remote is pressed, the XLR inputs will be selected. So
the original input is still available, when the
AUX
button is
pushed, the
CD
input will be selected.
TUNER
Intended for the analogue outputs from an FM, AM
Phono input
Phono-level input
The A49/C49 provides a pre-amplification stage to treat
the low-voltage output from a MM (moving magnet)
cartridge. Input specifications are given on pages 20 - 21.
Output volume is shown on the front display as
PHONO 20
, for example.
Line-level phono input
The phono input may be changed from line-level to
phono-level. Either use the
MENU
button on the remote to
access the setup menu, or press the front panel
PHONO
and
BALANCE
buttons simultaneously and use the control
knob to change the setting. The front panel display shows
LINE- OFF
(i.e. phono) or
LINE- ON
respectively.
If you wish to use an external phono amplifier, connect
its output to the
PHONO (MM)
input, but make sure that
LINE- ON
is selected, since a phono amplifier produces
line-level input.
With the input defined in this way, output volume is
shown on the front display as
LINE- 20
, for example.
WARNING: NEVER play a standard line-level source into the
phono input when set to LINE-OFF. This would result in serious
damage to both your amplifier and speakers due to the extra
gain that is applied and would not be covered under warranty.

Connecting to an additional
power amplifier
The A49/C49 provides a pair of unbalanced pre-outs on
standard RCA phono connectors and a set of balanced
pre-outs on XLR connectors to allow connection to
an additional power amplifier to create a bi-amplified
setup.
Most audio amplifiers, including the Arcam P49/
P349, will connect to the RCA phono connectors
using standard interconnect cables. This connection is
recommended for short cable runs. Connect to the
PRE
IN
connection of the power amplifer
If however your amplifier has balanced connections,
you may use the balanced XLR output. This connection
provides greater rejection from electrical interference
and is useful when cables are long (more than a few
metres) or in electrically-noisy environments. Balanced
connections also have the ability to reject ‘hum’ caused
by ‘ground loops’. Connect to the
PRE IN
connection of
your power amplifier.
Recording an audio source
The A49/C49 allows you to record and monitor the
sound from any connected source.
The back panel
REC OUT
socket can be connected to the
input sockets of your recording device (these are usually
labelled
RECORD
or
IN
).
To record from a particular source, press the
appropriate source button (for example,
TUNER
).
Adjusting the balance
The balance setting allows you to increase the volume of
one channel (left or right) relative to the other. Altering
the balance may help to restore the stereo image for an
off-centre listening position.
Balance can be adjusted from the front panel or from
the remote control. Press the
BALANCE
button (or
BAL
on the CR902) to view the current setting, then use
the control knob (or the
+/–
buttons on the remote)
to change the setting – from
L9
to
R9
, via the neutral
value
0
.
Speaker Control
The SP1 and SP2 switches (A49 only) enable and disable
the respective speaker outputs. The LED will be lit if the
speakers are enabled.
Listening
Volume control
Use the control knob (or the
+/–
buttons on the remote)
to change the volume. Turn the knob clockwise to
increase the volume, anti-clockwise to reduce it.
Listening using headphones
The headphones socket (
PHONES
) accepts headphones
with an impedance rating between 8Ω and 2kΩ, fitted
with a 3.5mm stereo jack plug.
The pre-amp outputs and speakers are muted when
headphones are plugged in and the front panel display
shows
HEADPHONE
.
The headphones socket is always active, unless output
has been muted.
Muting output
The output of the A49/C49 can be silenced by pressing
MUTE
on the front panel (or
-
on the remote control).
If the unit is muted, the power light changes to orange
and the source is shown on the front display panel (e.g.
PVR MT
).
Press
MUTE/
-
for a second time (or change the volume)
to cancel mute.
Connecting to a source
component with a balanced
output
In addition to the seven single end (RCA) inputs, the
A49/C49 provides a single balanced input on female
XLR connectors.
If your source component (such as the Arcam D33)
has balanced audio outputs you may wish to use this
connection instead of the single ended inputs. This type
of connection provides greater rejection from electrical
interference and is useful when cables are long (more
than a few metres) or in electrically-noisy environments.
Balanced connections also have the ability to reject
‘hum’ caused by ‘ground loops’.
Processor mode
Processor mode can be assigned to any input. In this
mode, the A49/C49 is set to a fixed level. Use
MENU
button on the remote and then use the control knob to
change the setting. The front panel display shows (e.g.)
PROC- AV
.
When this input is selected, the volume display will show
PM
instead of the volume level.
To alter the level use the
MENU
button on the remote to
access the setup menu then use the control knob to
change the setting. The front panel display shows (e.g.)
