Installation of multiple units
Can you stack Pantages G4 units on top
of each other without an air space in
between?
You can stack a maximum of 4 units
on top of one another, and allow a free
rack space above and below.
Ideally, 2 units can be stacked with a
free space above and below, as this
will improve the ventilation to the
units.
Can you daisy chain or y-cord audio and
power trigger connections?
Daisy chaining audio is easy, as there
are Loop output jacks, which can be
used to drive the next amplifier.
The 12 volt mini jacks are powered to
turn on another unit when the main
unit is on (not standby). If you need
more than 15 milliamps current on the
12 volt output, use a relay to prevent
over loading The Pantages G4. (It only
takes 1 milliamp to turn on.)
What are the power requirements and
BTU outputs of amplifier?
More detailed information is shown
in the Specifications table at the end
of this manual. In general, we feel a
conservative, real life design criteria
is 1/8th power. This will be a quite
loud listening level for most rooms
and assumes all zones driven at the
same time. You will be amazed at how
cool the Pantages G4 is at this level.
One rule does not fit all situations, so
apply your knowledge of the particular
circumstances involved. Also, see the
section below on unique rooms and
SPL.
How many units may I put on one 15
amp breaker?
It depends. Since you are limited to
1800 watts per device by most codes,
there should be a separate 15 amp
circuit for each unit.
The circumstances where Pantages
G4 draws maximum power are very
rare outside of an engineering lab.
Maximum power is using a sine wave
input which has at least a third higher
energy density than music. This would
mean that all channels are operating
at maximum, an unlikely situation
even during a really fun party. Even
more unlikely is all channels on multi-
ple units operating at full output.
You know the system better than we
do, so it is your decision. If the only
use is background music, then the
one-eighth power in the specifications
is a reasonable (actually conserva-
tive) power draw. Of course, you will
want to include a margin of safety for
unusual circumstances. And in the
final analysis, you have to do what the
electrical inspector tells you to do.
