User manual BIAMP MPA250

[. . . ] The apparatus shall not be exposed to dripping or splashing and no objects, such as vases, shall be placed on the apparatus. Unplug this apparatus during lightning storms or when unused for long periods of time. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. Refer all servicing to qualified service personnel. [. . . ] Assembled in India AVIS: RISQUE DE CHOC ÉLECTRIQUE - NE PAS OUVRIR E215636 CAUTION I CAUTION: Risk of fire replace fuse only with same type T 6. 3 A L 250 V RISK OF ELECTRICAL SHOCK. DO NOT OPEN. Use only with a 250V fuse Employer uniquement avec un fusible de 250V signal / peak temp / fault UNBAL 775mV OFF level O BAL 300mV HPF ~120V 60Hz 900 Watts 8 70V 25V 25V CT COM OUT XFMR INPUT 4 GND input Input: This plug-in barrier strip provides the line-level input to the amplifier. For unbalanced input, wire high (+) and ground ( ). For balanced input, wire high (+), low (-), and ground ( ). NOTE: The UNBAL / BAL switch must be in the appropriate position (see below). Level: This screw-driver adjustable control determines the level of input signals allowed into the amplifier. Level provides a gain range from 'off' (min. ) to 'unity' (max. ). The Level control is factory set for -20dB of gain, which will produce maximum output power with input signal peaks of +20dBu. For best performance, first adjust the source signals for optimum (maximum) levels, then adjust the amplifier Level control for the desired volume. Signal / Peak Indicator: This 2-color LED indicates the signal level for the amplifier. When the LED is green, the amplifier has signal (above -30dB). When the LED is red, the amplifier signal is clipping (max. CAUTION: Signal levels should be adjusted to avoid clipping. Clipping can cause severe distortion, over-temperature conditions, and even loudspeaker damage. NOTE: Signal / Peak indicators will turn off during Temp / Fault conditions (see Temp / Fault Indicators below). This indicator also appears on the front panel. Temp / Fault Indicator: This red LED indicates over-temperature and output fault conditions for the amplifier. When the LED remains lit, the amplifier has an over-temperature condition. When the LED is flashing, the amplifier has an output fault condition. Either condition will temporarily de-activate the amplifier, causing the Signal / Peak LED to turn off as well. The amplifier will attempt to self-reset once the over-temperature or output fault condition is resolved. This indicator also appears on the front panel. [. . . ] If you notify BIAMP during the warranty period that a BIAMP Systems product fails to comply with the warranty, BIAMP Systems will repair or replace, at BIAMP Systems' option, the nonconforming product. As a condition to receiving the benefits of this warranty, you must provide BIAMP Systems with documentation that establishes that you were the original purchaser of the products. Such evidence may consist of your sales receipt from an authorized BIAMP Systems dealer. Transportation and insurance charges to and from the BIAMP Systems factory for warranty service shall be your responsibility. [. . . ]
