The top unit of the active PROJECTOR system houses a 12" B&C woofer
and a B&C 2" high-frequency driver, both loaded onto 60° x 40°
concentric horns, as well as all the necessary active electronic components
to control and drive them. The Mid Throw / Long Throw switch lets you
choose one of two frequency compensation options for either short and
middle distances or long distances. For distances up to 20 meters, set the
switch to Mid Throw; for distances greater than 20 meters, set it to
Long Throw.
The enclosure is equipped with casters and Aeroquip flight rails as
standard features. These rails, which are mounted on both sides and in a
recessed groove on the rear panel, make it easy to fly the cab.
Rear Panel:
1. INPUT
Electronically balanced input designed to accept the balanced output
signal coming from the mixer (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. MF AND HF 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. The limiter status of the
middle (MF) and high (HF) frequency ranges is indicated in each case by a
dedicated LED.
5. GROUND
Ground lift switch for separating the signal and chassis ground 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 the button in.

6. MID THROW / LONG THROW SWITCH
Selects appropriate frequency compensation depending on distance. In
LONG THROW mode, the system's EQ boosts high frequencies by about
three decibels so that the top end is not lost when the signal is projected
over greater distances. For distances up to 20 meters, set the switch to
MID THROW, for greater distances to LONG THROW.
7. VENTILATION UNIT
This ventilating fan keeps the power amp modules cool. Always make sure
that the fan and the vents are kept free of dirt and debris and that they
remain unobstructed so air can circulate freely.
8. 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)!
9. MAINS INPUT
This Neutrik Powercon socket accepts the mains cable. This is a relatively
new type of connector system featuring a locking mechanism which
prevents the mains cord from being pulled out inadvertently.
10. "POWER" SWITCH
On/off switch for the electronics in the speaker cabinet. It lights up red
when the cab is powered up.
11. AEROQUIP FLIGHT RAILS
These rails are designed to accept steel cables equipped with Aeroquip
studs (see the chapter on Setup / Stacking) to fly the cabinets safely
and securely.
