User manual BIAMP EQ 28-8 AND EQ 282-8

[. . . ] Refer all servicing to qualified service personnel. 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. Do not defeat the safety purpose of the polarized or grounding-type plug. [. . . ] The standard fuse is held in the clip, and becomes the actual AC fuse when the Fuse Clip is installed. Replace the standard fuse only with the same value and type. For ~115 VAC operation, use a T 3A L 250V fuse. For ~230 VAC operation, use a T 1. 6A L 250V fuse. Voltage Selector Switch: For 115 VAC operation, slide to the left position toward 115V. For 230 VAC operation, slide to the right position toward 230V. Channel Level Controls: These controls adjust the input signal level for each channel. After setting appropriate levels at the signal source, then adjust the Channel Level Controls for the desired output volume from the EQ 28-8 AND EQ 282-8. In mono-bridge mode, Channel 1 becomes the active input and Channel 2 input is inactive. As an option, the Channel Level Controls may be mounted to the EQ 28-8 AND EQ 282-8 front panel (see Internal Modifications: Front Panel Level Controls on page 9). NOTE: Modifications must be performed by qualified service professionals. The voltage selector is indicated on the rear panel at the power cord receptacle. The EQ 28-8 AND EQ 282-8 is shipped from the factory set for 110VAC operation. If it is necessary to set the AC voltage selector for 240VAC operation, be sure to replace the AC fuse with the appropriate value. The High-Pass Filters must be enabled whenever using the EQ 28-8 AND EQ 282-8 for driving distributed speaker systems (see Internal Modifications: High-Pass Filter on page 5). Never connect the red (+) speaker binding posts directly together. This can result in internal damage to the amplifier. Before turning power on, set the EQ 28-8 AND EQ 282-8 level controls to the fully counter-clockwise (off) position. The EQ 28-8 AND EQ 282-8 is designed to be installed in a standard 19" equipment rack. The amplifiers have cooling vents on both the top and bottom panels. Do not block the cooling vents in any way. When mounting the EQ 28-8 AND EQ 282-8 in a rack, leave at least one rack-space above and below the amplifier to allow proper air flow. [. . . ] Front Panel Level Controls: The Channel Level Controls may be moved to the front panel of the EQ 28-8 AND EQ 282-8. Remove the plugs from the front panel mounting holes (save them for the rear panel mounting holes). Remove the knobs from the level controls. Remove the nuts from the level controls using a 11mm (7/16") nut driver. [. . . ]
