CAZ1400-AMPLIFIER

The CAZ1400 is designed for continuous duty in speech, music,
paging, and sound reinforcement applications demanding high
performance, exible features, and rugged dependability.

The CAZ1400 is rated at a continuous output of 310 watts per
channel into 8 ohms, 450 watts per channel into 4 ohms, and 800
watts per channel into 2 ohms. In bridge mode, the CAZ1400 is
rated at 900 watts into 8 ohms and 1400 watts into 4 ohms.

A switchable low-cut lter eliminates low-frequency energy below
30 Hz for tighter bass response, and a switchable limiter protects
loudspeakers from spurious transients and hard clipping.
Inputs are balanced/unbalanced 1/4" TRS and XLR line input jacks
for each channel, as well as screw terminal connections for the two
discrete, actively balanced inputs.

CAZ1400

STEREO POWER AMPLIFIER

Features

• 1400 watts continuous at 4 ohms bridged

Speaker connections are made with screw-terminals for Channel A,
Channel B, and Bridged Mono. Front panel detented gain controls
provide independent level-setting for each channel. Signal present
and overload LEDs, located above each gain control, provide visual
feedback for monitoring the output signal level.

The CAZ1400 has two variable speed fans, one in the front and one
in the back, to keep it cool no matter how hard it is driven. As the
power output increases, the fan speed increases to move more cool
air through the chassis and away from the internal heatsink and
power transistors, increasing the life span of the amplier.

Five year warranty.
