Arcam Delta 290P - Manual (Page 8)

The Delta 290P can drive two pairs of
loudspeaken, simultaneously if req^uired,
providii^ both pairs are raced between 8 and
16 ohms. Either pair can be selected using
the switches labelled SPl and SP2 on the
front panel. To avoid overheacii^, the
combined load impedance as seen by the
amplifier should not fall below 4 ohms per
channel.
CONNECTING YOUR SOURCE
COMPONENT
® PWR AMP IN -Connect to your pre­
amplifier ouqsuts.
® PREAMP OUT: The 290P can be
connected to provide two mono outputs
from a single input. Using the U-link ®
supplied,
cormect the PREAMP OUT
sockets ® together.
Utilising one Delta 290P per loudspeaker in
this maimer will allow bi-amplifying ofbi-
wireable loudspeakers. This is particularly
beneficial for top quality stereo installations
with a separate pre-ampUfier, or for the left,
centre and i^ht channel loudspeakers in a
five speaker Dolby Pro Logic system.
Contact
your Arcam dealer for more
detailed information.
■ Daisy Chain - The Delta 290P is capable
of driving further Delta 290P amplifiers (or
any other power amplifier), to drive more
speakers (eg. those in other rooms or tri-
amplified speaken etc). Connect the extra
power amplifier inputs to the PREAMP
OUT ouq>uts ® left to left, right to tight.
FRONT PANEL
SPl and SP2 - Pressing the SPl switch turns
on the speakers connected to the SPl
(upper) set of output terminals on the rear
panel. Similarly the SP2 switch turns on the
speakers connected to the SP2 (lower) set of
output terminals.
■ Both the SPl and SP2 switches can be
turned on at the same time, provided chat
the combined impedance of the two pairs of
speakers does not fall below 4 ohms per
charmel.
Important note: If both switches are turned off
then the amplifier will appear not to be
ftinctioning. as all speakers will be switched off!
® HEADPHONES SOCKET - Accepts
headphones rated between 8ohms and
2kohms fitted with a 6.3mm stereo jack
plug. If your headphones are fitted with a
different plug contact your dealer for a
suitable adaptor.
■ The headphone socket is always switched
on, irrespective of the positions of switches
® and ©.
® POWER - Switches the power on and off.
© POWER LED - This will initially ^ow
amber. After a few seconds, it will ^ow
green. When the LED gjows amber, the
speakers are disconnected and an internal
protection circuit is activated.
■ If this LED glows amber during normal use
it may be due to the amplifier overheating or
an ouqiut overload. Check the amplifier is
properly ventilated. Switch the amplifier off
and wait for 2-3 minutes before switching
