Passion for Perfection
OVERVIEW
The Ha er CI-1255e is designed primarily for the custom installation and commercial markets. It is used to power speakers in multiple
rooms, using a single audio source or many individual sources. With 12 channels rated for 55 watts per channels at 8 Ω, the CI-1255e
packs some serious punch. Each channel has a recessed gain control, rear and front mounted LED signal presence indicators,
individual channel clip indicators, individual RCA inputs for each channel, and a global bus that allows you to connect one stereo
source and have it feed as many of the stereo pairs as you like. The CI-1255e is turned on and off via the front panel power switch
and with ECOSYSTEM™, it automatically turns itself off when no signal is present for energy savings. The CI-1255e will automatically
spring back to life in 10 milliseconds as soon as signal is detected. The front panel also has a power present indicator and an
ECOSYSTEM indicator that illuminates when all channels are shut down saving energy. Unlike other multi-channel amps that employ
switch-mode class D or H type amps, the Ha er CI-1255e employs an extremely accurate class AB topology for the most demanding
audio critic. This means that it is perfectly suited for home theater applications and listening rooms where sound quality is of utmost
concern.
