SPEAKER CONNECTIONS
PLEASE NOTE!: Do not operate the amplifier with the speakers disconnected.
The A3500-SS is designed to run one pair of stereo speakers.
On the rear panel are six gold plated speaker terminal posts with screw locks.
These are for speaker cables with 4mm plugs or bare ended 8AWG (max) cable.
Connect 8 OHM speakers to the terminals marked 8 OHM and Common.
Connect 4 OHM speakers to the terminals marked 4 OHM and Common.
If you are unsure of the load then use the 4 OHM terminals.
Connect the speaker cable POSITIVE to the RED terminal (8 OHM or 4 OHM)
Connect the speaker cable NEGATIVE to the BLACK terminal (common)
Ensure that the Left and Right speakers are the correct way around as labeled.
Check that polarities between amplifier and speakers are correct for both channels.
Do not connect more than one pair of speaker cables to the A3500-SS terminals.
Do not connect speakers to both the 8 OHM and 4 OHM terminals.
SPEAKER CABLE WITH FITTED 4mm BANANA PLUGS
Insert the speaker plugs fully into the holes provided in the back of the terminals.
SPEAKER CABLE WITH BARE WIRE
Clean strip the ends of the speaker cable about 15mm (5/8"). Ensure that there are no
loose strands. Unscrew the speaker terminal cover anti clockwise to allow enough room.
Insert the bare ended speaker cable into the 4mm entry hole located on the side of each
speaker terminal. Accepts up to 8AWG cable thickness. We recommend premium cable.
Screw down the speaker terminal cover clockwise until the cable is secured firmly.
Do not use a wrench to tighten the speaker terminals as you may cause damage.
We recommend keeping cable distances to a minimum and to use high quality speaker
cable as the better the interconnects, the more detail you will hear from your equipment.
SPEAKER POSITION
To achieve optimum sound stage and depth of field, we recommend to position the left
and right speakers between 2.7 to 3.5 Metres apart and to angle both speakers in towards
the centre listening position by around 5 degrees. Avoid positioning the speakers too
close to an adjacent or back wall. A minimum distance of 0.25 to 0.75 Metres is advised.
Fine-tune the speaker’s position to suit your room acoustics using a known recording.
Please note that all rooms are different, so you may want to experiment with various
positions and orientations of your speakers until you are satisfied with the sound.
INPUT CONNECTIONS - RCA
There are four pairs of Gold plated RCA sockets for
connection to four audio sources.
Each pair is labeled corresponding to the front panel
selector switch and accepts Line Level Stereo
connection to any typical hi-fi system RCA outputs.
All 4 inputs are electrically identical and only differ
in how they are labeled. We recommend gold plated
premium quality audio leads be used for long and
reliable service. If you want to connect a turntable,
the A3500-SS requires an optional external phono
RIAA equalised pre-amp.
