Connecting

loudspeakers

loudspeakers
There are many different ways of connecting
loudspeakers to your A39. The following section
describes how to connect the speakers and amplifier for
the most common configurations.

Normal single wiring

For single wiring, we recommend that you use the
SPEAKER 1 set of terminals on your amplifier. If each
R
speaker has more than one pair of connecting terminals,
use the terminals labelled LF or 'Low Frequency' .
Connect the red positive terminal of the right speaker
HF
PHONO
connection on the amplifier (labelled ) to the positive
R+ GROUND PHONO
ONLY (MM) CD TUNER SAT BD
terminal of your right speaker. Similarly, connect the
LF
black negative terminal of the right speaker connection
on the amplifier (labelled ) to the negative terminal
R-
of your speaker. Repeat the process for the left speaker,
using the terminals labelled and on the amplifier.
L+ L-
WARNING: If your speakers support bi-wiring, there will be a
strip of conductive metal connecting the low-frequency ( LF )
terminals to the high-frequency ( HF ) terminals; this MUST NOT
BE REMOVED in a single-wired system.

Bi-wiring

Bi-wiring is performed in the same way as single wiring
except that, a pair of cables are used to connect the
R
amplifier to each speaker.
Follow the instructions given for single wiring; then
perform the same actions, this time connecting the
HF
PHONO
set of terminals on your amplifier to the
SPEAKER 2
GROUND PHONO
ONLY (MM) CD TUNER SAT BD
Remove metal
terminals labelled HF or 'High Frequency' for each
LF strip
speaker.
WARNING: Speakers that support bi-wiring have a strip of
metal that connects the low frequency ( LF ) terminals to the
high frequency ( HF ) terminals. This MUST BE REMOVED in a
bi-wired system.
Notes on making speaker connections
< Do not make any connections to any amplifier while it is switched on. We recommend that your
amplifier is completely disconnected from the mains supply before starting.
< Before switching your amplifier(s) on for the first time after connecting to speakers, please check all
connections thoroughly. Ensure that bare wires or cables are not touching each other or the amplifier'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 amplifier and the speaker.
< After making connections: switch the amplifier on, 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, please contact your Arcam dealer who will
be happy to help you.

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.

Phono input

Phono-level input
The A39 provides a pre-amplification stage to treat
the low-voltage output from a MM (moving magnet)
cartridge. Input specifications are given on page 13.
Output volume is shown on the front display as
PHONO 20, for example.
Line-level phono input
The phono input may be changed from phono-level to
line-level. 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 input, but make sure that
PHONO (MM)
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.
