The PROJECTOR SUB 1 and SUB 2 subwoofers
are each equipped with a horn-loaded 18" B&C speaker. The horn and
pressure chamber of these cabinets are designed so that sound pressure
waves actively cool the massive magnet and voice coil of the 600-watt
speaker; the harder it works, the stronger the cooling effect.
The interiors of the two subwoofers are identical, though the SUB 2's
layout is actually a mirror image of the SUB 1's. There is a simple yet very
compelling reason for this design. When you stack the subwoofers (see the
diagram "Stacking subwoofers") as intended, the two halves actually form
a full horn so that the configuration delivers more bottom-end sound
pressure over a greater distance.
Rear Panel:
1. INPUT
Electronically balanced input designed to accept the balanced output
signal from the mixing console by way of the THROUGH output of the
Projector Mid/High Unit (1= ground, 2= +, 3= -)
2. THROUGH
This is a parallel output you can use for routing the LINE signal to
additional equipment, such as other systems, individual components,
monitor power amps, etc
3. GAIN
This knob lets you adjust the power amp to match the input signal level;
reduce it to prevent distortion when you're patching in signals that are
already fairly hot.
4. LF LIMITER LED
Indicates the operating status of the limiter. Green = signal present,
yellow = soft limit, red = full limit. NOTE: This is not a clipping indicator;
it is acceptable for it to light up every now and then in red. This tells you
that the limiter is operating at full capacity.
5. GROUND
Ground lift switch for separating the signal and chassis ground from each
other when you encounter problems with hum due to ground loops
resulting from duplicate paths to ground. The connection from signal
ground to chassis is interrupted when you press this button in.

6. VENTILATION UNIT
This ventilating fan keeps the power amp modules cool. Always make sure
that the fan and the ventilation vents are kept free of dirt and debris and
that they remain unobstructed so air can circulate freely.
7. CIRCUIT BREAKER
This automatic circuit breaker serves the same purpose as the standard
fuses that you may be familiar with. If it trips, once you have identified
the problem you can reset the circuit breaker by simply pressing it.
Caution: Always switch the system off before you reset the circuit breaker
(take a look at the mains power switch and make sure it is set to OFF)!
8. MAINS INPUT
Neutrik Powercon socket designed to take the mains cord. A new type of
connector system featuring a locking mechanism, it prevents the mains
cord from being pulled out inadvertently.
9. "POWER" SWITCH
On/off switch for the speaker cabinet. Lights up red when the cab is
powered up.
