INSTALLATION
AMS35i
INTRODUCTION
POWER CONNECTIONS
Congratulations on the purchase of the new AMS35i Class A
Integrated amplifier. Great attention has been paid to internal
layout, isolating each circuit section to prevent possible
interaction.
The AMS35i is supplied with a standard IEC mains cable
which plugs into the IEC socket at the back of the unit (see
P.7)
The unit features a finely tuned and tweaked , for smooth
sound coupled with low noise and virtually no distortion.
The power amplifier consists of two monoblock class-A
amplifier modules with separate supplies for the absolute best
in separation and imaging. Generously rated, they are enough
to drive even the most demanding loudspeakers with ease.
Low distortion and very quiet they will deliver all music types
exactly as the artist originally intended.
The resultant performance achieved by this unit is among the
best in the world. It has excellent signal to noise ratio, low
distortion, wide bandwidth and dynamic range, with
extraordinary resolution and fine detail.
AUDIO CONNECTIONS
RCA Inputs: Connect all RCA single-ended sources to
relevant analogue inputs (see p.7 For more information). Use
good quality fully connected (signal and ground) coaxial
phono cables for all RCA signal connections.
XLR Inputs: Connect all XLR balanced sources to relevant
analogue inputs (see p.7 For more information). Use good
quality fully connected (signals and ground) balanced XLR
cables for all XLR signal connections.
Outputs: Connect loudspeakers to the terminals on the back
panel marked as LEFT and RIGHT SPEAKER outputs
CLEANING
Before cleaning the unit, switch off power at the mains switch
and remove the mains plug from the wall socket.
Clean the cabinet and remote control unit using a moist cloth.
Using solvents, white spirit or thinners is not advised, as they
could damage the surface finish.
The TAPE output allows loop through of analogue signals
for example, to pass on to recorder or monitor. It is also the
ideal output to connect our headphone amps into.
The PRE-OUT output allows analogue signals controlled by
the volume, to pass on to a second amplifier. This is useful
for bi-amping.
INSTALLATION
Position the AMS35i on a stable, horizontal surface where
there is no risk of it being knocked, or subjected to vibration
such as from loudspeakers.
Important note:
As a “CLASS A” amplifier, the unit dissipates a quantity of
power at all times, and it is important that it is adequately
ventilated. The top and bottom are perforated to allow the
smooth flow of heat through the unit. It is therefore not
recommended that the unit is enclosed in a cabinet or placed
where the ventilation holes are impeded as this could result in
the unit cutting out due to excessive heat build-up.
The AMS35i must be protected from humidity - if the unit is
moved from a cold place to a warm room, leave the unit for an
hour or so to allow sufficient time for the moisture to
evaporate.

REMOTE CONTROL
AMS35i
Remote control Handset (supplied with the battery already installed).
The AMS35i remote control shown below enables functions from this unit to be operated from a convenient distance.
Equivalent buttons on the remote control have the same functions as those on the front panel of the unit. Other
functions are only available by remote control.
As the handset uses an invisible infra-red light beam, the front edge must be pointed directly towards the receiver
window at the front of the player, without visual obstruction between them.
For reliable remote control operation, the AMS35i should also be positioned so that direct sunlight, fluorescent or
other bright lights do not fall directly on the IR receiver lens (see P.7). Such light can interfere with remote control
operation and/ or maximum operating range.
If the range of the remote control greatly decreases, replace the battery, VARTA Lithium Li-Mn button type CR2450.
Please dispose of used batteries in accordance to local regulations.
Changing the Battery
If the remote fails to operate the AMS35i
functions correctly, or
a
substantial
reduction in range is observed, the
battery may be exhausted.
1. Remove the six screws in the base of
the remote control.
