Eastern Acoustic Works CAZ1400

The CAZ1400 is designed for continuous duty in speech, music, paging, and sound reinforcement applications demanding high performance, flexible 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 filter 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.

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 amplifier.
