The Hafler CI-855e™ is a powerful 8-channel amplifier designed for high quality audio and reliable performance in any venue, from home theaters and multi-zone houses to restaurants, sports facilities, and houses of worship.

Following Hafler’s tradition of refusing to compromise on audio quality, the CI-855e features true Class-AB circuit design and each channel delivers 55 watts RMS into 8 Ohms (70 watts RMS into 4 Ohms). Channels 7 and 8 can be configured in bridged mono to provide 180 watts RMS power to a subwoofer. Checking for input levels is made easy with front and rear signal presence LED indicators, as well as front panel peak indicator LEDs. Gain controls on each channel allow for precise level adjustment. The CI-855e employs a Fault-Safe™ circuit which will automatically shut down any channels that have a problem present; powering them back on once the fault is removed.

Inputs include gold plated RCA connectors for each channel, which won’t tarnish over time and will provide optimal signal transfer. A global stereo bus can be sent to all of the channels simultaneously, and is wired in parallel with a 3.5mm input on the front panel. This provides ready access for testing during installation, allowing for connection to an iPhone®, tablet or other device. The outputs utilize Euroblock (Phoenix® style) connectors for quick and easy installation. An OmniPort™ input allows optional modules to be installed that provide additional connectivity options, such as a Dante® digital network card, Jensen transformer-isolated inputs, or Euroblock (Phoenix® style) inputs.

Housed in a durable 17” x 3.5” x 11.5” (432 x 89 x 292mm) solid steel enclosure, the CI-855e can also be rack-mounted in a standard 19” 2 RU rack using optional rack ears. A HushTone™ side-mounted ultra-quiet fan pressurizes the chassis to circulate air for cooling, while only generating a mere 28dB. The onboard ecoSYSTEM™ energy saving circuit powers the amplifier off after 1 minute of inactivity, automatically powering back on within 10 milliseconds when signal is detected at the inputs. To address international usage, the CI-855e is equipped with a dual-voltage toroidal power transformer with a selector switch for 115V and 230V operation, and is TUV safety certified.

The Hafler CI-855e delivers rock solid dependability with an uncompromising circuit design to bring the highest quality sound to any multi-zone audio installation.
