2 Installation
The Phoenix HG 15 should be rack-mounted.
Although it is valve based, therefore producing more heat
than solid state units, it can be racked with no space above,
as long as the room temperature is within the range 0-25°C
and there is adequate ventilation beside and at the rear of
the unit to dissipate heat.
Input and Output connections are standard XLRs with pins 2
and 3 Signal, (transformer ‘balanced’) and pin 1 ground. If
coming from and to unbalanced sources, pin 2 should be
“Hot”.
DON’T FORGET TO CHECK THE MAINS VOLTAGE
SWITCH IS CORRECT FOR YOUR AREA
.
(230/115V = 220-240V / 110-120V) Check the fuse is correct
(see table).
This will usually be set at the factory if the destination is
specified, eg. 115V for North America and Japan, 230V for
other destinations.
The Link phono socket is provided so that 2 HG15s can be
linked together for stereo operation. A standard phono to
phono cable can be used for this purpose.
2.1 Metering
When the unit is warmed up (allow about 5 minutes),
set the compression meter to zero. The adjustment is
just below the meter itself and can be done with the
tool provided. Do not adjust the screw on the meter
itself unless the needle is not horizontal when the unit
is cold.
The Metering is not necessarily accurate so use it as a
guide only.
