CLEARONE XAP 800 PDF

Each input shall also be able to reference any output or any of four global reference buses for echo cancellation. The unit shall have four internal and four global automatic microphone mixers, each with fully adjustable parameters. The microphone mixer shall use PA adaptive, adaptive ambient, chairman override, first mic priority, last mic mode, number of open mics, and look-ahead gating. Any input can be routed to any output or multiple outputs. Signal processing shall be provided by eight assignable processing blocks, each with 15 programmable filters, delay, and compression.

This professional grade amplifier features a dB signal-to-noise ratio with 0. The XPA is one quarter the size of comparable amplifiers, conserving rack space and weighing only 2.

The Extron exclusive, high efficiency design generates very little heat and allows the amplifier to be convection cooled. With an auto power-down feature that automatically places the amplifier into standby after 25 minutes of inactivity, it consumes just 10 watts when idle and less than 1 watt in standby mode.

The XPA is housed in a compact 1U, half rack width enclosure. This amplifier is UL plenum rated, allowing for a concealed installation above a drop ceiling to prevent theft while providing convenient placement of AV equipment.

The XPA two channel amplifier delivers watts rms per channel into 4 ohms or 60 watts rms per channel into 8 ohms for amplification of voice or program audio content to stereo speakers, or two sets of 8 ohm ceiling speakers in a dual zone application. The XPA accepts balanced and unbalanced input signals and includes recessed, detented level controls located on the rear panel to prevent tampering. These controls allow for adjusting audio system gain structure, or setting individual levels for each zone.

For applications requiring volume adjustment and muting control from a location other than the amplifier, remote control capability is available using the optional Extron VCM or VCM analog volume and mute controller or VC 50 analog volume controller. Additionally, the XPA includes multiple protection circuits that momentarily activate when an abnormal condition, such as overheating, is detected. An advanced, automatic clip limiter protects speakers from clipping distortion. Features Inputs: Balanced or unbalanced stereo on a 3.

CDRS eliminates the high frequency switching ripple characteristic of Class D amplifiers, a source of RF emissions which can interfere with sensitive AV equipment such as wireless microphones. Convection cooled, fanless operation — The XPA does not require internal fans or vents for cooling, ensuring quiet, reliable operation.

It generates substantially less heat than conventional power amplifiers, making it ideal for rack-mount applications. Ultra low inrush current — no need for power sequencing — Allows multiple XTRA Series amplifiers to be powered on simultaneously without overloading power circuits.

This eliminates the need for power sequencing. Rack-mountable 1U, half rack width enclosure — With the capability to deliver full-sized amplifier power in one quarter to one half the size of many comparable power amplifiers, the XPA reduces rack space requirements for many installations.

Above-the-ceiling placement conceals the amplifier to prevent theft, and is convenient for installing equipment when space inside the room is limited. Auto power-down with fast power-up — The XPA meets ENERGY STAR qualification requirements with an auto power-down feature that automatically places the amplifier into standby after 25 minutes of inactivity, dramatically reducing power consumption.

It quickly returns to full power status in less than one second upon signal detection. Rear panel recessed, detented level controls — Provide attenuation of input signals for adjusting audio system gain staging as well as two-zone applications. They are located on the rear panel to prevent users from tampering with level adjustments. Automatic clip limiter — Detects actual onset of clipping by comparing input and output waveforms. Gain is automatically reduced with a slow attack and fast release to eliminate clipping.

This advanced limiter design protects the speakers from clipping distortion and offers superior sonic characteristics compared to limiters that use signal compression.

Multiple protection circuits — Activate during output shorts, thermal overload, or DC faults to prevent damage to the amplifier and speakers. Remote standby port — Enables the XPA to be remotely powered down when not in use, reducing operating cost. Remote volume and mute control port — In basic installations without control systems, this port allows the XPA to be remotely controlled using the optional Extron VCM or VCM analog volume and mute controller or VC 50 analog volume controller.

Bridgeable outputs — The power output of the XPA can be effectively doubled by bridging the output. A mono source is wired to both the left and right input while the output is wired for bridged operation.

Bridging allows power to be output at watts into 8 ohms or watts into 16 ohms. The minimum load impedance when bridging is 8 ohms. See manual for complete wiring details.

Front and rear-mounted signal and protection indication LEDs — Provide convenient indication of input signal presence and protection circuit activation from both sides of an equipment rack. Front panel over-temperature LED — Provides visual indication that the enclosure temperature has exceeded the optimal value, well in advance of the onset of thermal protection circuitry.
