LOCATION

We recommend that you place the Forte as close to the loudspeaker as possible, as
this reduces the length of speaker cable required. Whilst this may make it necessary
to use longer interconnect cables, long interconnects cause less sonic degradation
than long speaker cables.
The unit may be placed on a stand or shelf, provided it is strong enough.
Alternatively, it may be placed directly on the floor. In this case, please ensure that
that the ventilation slots on the base of the unit are not obstructed by carpeting or
other floor covering.
Do not stack Forte units on top of each other or place them on top of another power
amplifier, or other source of heat.
Always allow a clearance of at least 3.5" (5cm) above the unit.
a clearance of at least 6" (15 cm) behind the unit, to enable the cables to be routed
without being subject undue strain.
Regardless of where you locate your amplifier, we advise positioning it well away
from sensitive low signal level components such as pre-amplifiers and turntables.
The Forte power amplifier dissipates approximately 80 watts as heat when idling (i.e.
no input signal). It is normal and perfectly safe for it to run somewhat warm to the
touch.

XLR CONNECTOR PIN ASSIGNMENT

The Forte is fitted with 2 XLR type balanced inputs. The pin assignments of the
Forte's XLR input conforms to the AES 14 standard, which is now commonly used
throughout the audio
Pin 1:
Pin 2:
Pin 3:
Connector shell:
Some equipment may have the polarity of the signals on pins 2 and 3 of the XLR
connectors swapped over. Please refer to the user manuals of the other equipment
in your signal chain to confirm whether this is the case.
If this is the case, it will not cause any damage, but it may reduce the quality of the
stereo image, as well as the perceived attack of the bass.
remedied by swapping the connections of pins 2 and 3 at either end of one of one set
of balanced cables in the signal chain. Alternatively you can swap over the polarity
of the speaker leads on both channels. Your dealer should be able to advise you on
the best course of action.
If two items in the signal path have the connections to pins 2 and 3 of the XLR
connector reversed with respect to the AES standard, this cancels out the problem
and you need take no further action.
