Delta no digital pre-amplifier
Cartridge loading modules
These optional accessories are passive, switchable modules
signed to modify the input impedance of the amplifier in order to
'obtain the best match with the cartridge in use. As the Delta 110 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/CJ cartridges
- are available on request from your dealer, distributor or the factory.
These modules are user adjustable via a series of small switches.
The appropriate MM or MC loading module should be
plugged into the amplifier on the pins located close to the disc input (see
section - Removal of Top Plate - below). 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 have a
subtle effect on 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.
Before fitting a cartridge loading module, it is ESSENTIAL to
note the precautions detailed below
Removal of top plate
The installation of a loading module is a straightforward
operation provided you follow the instructions. If you are in any doubt,
please consult your dealer
Should you need to install a cartridge loading module, before
removing the top plate ALWAYS SWITCH OFF THE AMPLIFIER AND
DISCONNECT IT FROM THE MAINS SUPPLY
Note that the mains fuse remains live whenever the amplifier
is plugged into the mains, even when the amplifier power switch is in
the'off'position.
To remove the top plate, unscrew the two black headed
screws at the top of the rear panel using a No. 1 'Pozidriv' screwdriver.
Lift the top plate vertically and pull it backwards slightly to release it.
Replacement is simply the reversal of this procedure.
Connecting cables
When dealing with high quality hi-fi systems, such as those
based around a unit with the resolving power of the Delta 110, the
question of connecting cables becomes of paramount importance. 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
