User manual BIAMP MPA250

[. . . ] Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. [. . . ] 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. 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). 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. CAUTION: The MPA250 is cooled by a variable speed fan, which exhausts warm air from the left side panel. To allow proper ventilation, an un-obstructed clearance of at least 0. 75" must be maintained along the left side panel of the MPA250. HPF Switch: This DIP switch provides a High-Pass Filter for the amplifier input. The High-Pass Filter is used to eliminate unnecessary lower frequencies (12dB/octave @ 125Hz) for speech and distributed speaker applications. [. . . ] 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. [. . . ]
