We recommend that you place the Legacy as close to the loudspeaker as possible, as
this reduces the length of speaker cable required. While 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.
Never stack Legacy 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. You must also allow
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 Legacy power amplifier dissipates approximately 400 watts as heat when idling
(i.e. no input signal). It is normal and perfectly safe for it to run hot to the touch.
XLR CONNECTOR PIN ASSIGNMENT
The Legacy is fitted with 2 XLR type balanced inputs. The pin assignments of the
Legacy’s XLR input conforms to the AES 14 standard, which is now commonly used
throughout the audio industry. These assignments are shown below:
Pin 1:
Signal ground
Pin 2:
Signal + (non-inverting)
Pin 3:
Signal - (inverting)
Connector shell:
Chassis ground
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. This situation is easily
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
