Arcam 290 - Adding Delta 290 P for Bi-Amplification; Bi-amplification Setup and Precautions

If the LED continues to glow amber, switch
the unit off, remove all the speaker cables
and switch on again. If the LED goes to
green on switch on then check the speaker
and speaker cables for short circuits before
reconnecting them. If the LED continues to
glow amber with no speakers connected
contact your Arcam dealer.
ADDING A DELTA 290P TO AN EXISTING
DELTA 290
If you are using a Delta 290, a Delta 290P can be
added to bi-amplify a pair of bi-wireable
loudspeakers. This will reap substantial
improvements in sound quality if the following
precautions are observed.
■ Always switch on the Delta 290 and allow it
to stabilise (indicator light turns green)
before switching on the Delta 290P.
■ The Delta 290 and Delta 290P power
amplifier are placed on separate shelves.
Stacking the units on top of each other will
reduce the sound quality slightly. It will also
reduce ventilation and consequently the
power handling capability.
■ The existing Delta 290 should be used to
drive the loudspeakers' HF (high frequency)
units. The new Delta 290P is utilised for the
LF (bass) drivers, as shown in the wiring
diagram below.
■ At the end of a listening session the Delta
290P should always be turned off first.
■ High quality interconnect cables should be
used between the Delta 290 and Delta 290P.
■ The use of high quality interconnect and
speaker cables in your system is essential to
obtain good sound quality. Cables from the
AudioQuest range are ideal partners for
Arcam products. Contact your dealer for
further details.
■ WARNING - Ensure that the links
connecting the red terminals and the black
terminals on the speakers are removed
before switching on the amplifiers. Failure
to do this could cause damage to one or both
amplifiers and this is not covered under the
warranty.
