Arcam Delta 60 - BOARD MODIFICATIONS

Delta 60 integrated amplifier handbook
Cartridge loading modules
These optional accessories are passive, switchable modules
designed to modify the input impedance of the amplifier in order to obtain
the best match with the cartridge in use. As the Delta 60 has a single set of
disc inputs (switchable to MM or MC via the switch on the rear panel),
then two separate loading modules - one for moving magnet (type
ULM/M) and one for moving coil (type ULM/C) cartridges - are available
on request from your dealer, distributor or the factory. These modules are
user adjustable via a series of small switches.
The loading modules should be plugged into the amplifier in
the position shown in fig 3. A set of instructions is provided with each
module. Care should be taken to ensure that only an MM loading module
is used in conjunction with moving magnet or high output moving coil
cartridges and that only an MC loading module is used in conjunction with
normal (low output) moving coil cartridges.
Under no circumstances adjust the loading module switches
when the amp is switched on and the volume turned up as severe damage
may occur to your amplifier or speakers.
It must be emphasised that these passive modules mainly affect
the sound balance and frequency response. They will have little or no
effect on the sensitivity of the amplifier. Most cartridges will perform
satisfactorily without any loading module.
Hints and tips
Getting the best from your Delta 60
Connecting cables
\X/hen dealing with high quality hi-fi systems, such as those based
around a unit with the resolving power of the Delta 60, the question of
connecting cables becomes of paramount importance. The higher the
resolution of the individual components involved, the higher the chance of
some of this hard won clarity being lost in the cables. We strongly
recommend that only first class loudspeaker and interconnect cables be used
with your hi-fi system. We have found interconnect and loudspeaker cables
from the AudioQuest range to be particularly suitable. Detailed information
on the AudioQuest range of cables may be obtained from your dealer or the
factory.
As a rule of thumb you might budget to spend between 5% and
20% of the price of your system on cable. Surprising though it may seem this
can be one of the most effective upgrades you can carry out on your system.
We suggest that you discuss the question of interconnect and
loudspeaker cables with your dealer.
