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

[. . . ] When the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. Use only attachments/accessories specified by the manufacturer. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. Unplug this apparatus during lightning storms or when unused for long periods of time. Connections to these teminals must be made by qualified personnel. 2 3 4 5 FRONT PANEL Channel Peak Indicators: These red LED indicators will light when their respective channel amplifiers have reached maximum output. [. . . ] The AC Power Cord is for connection to three-prong grounded AC outlets. CAUTION: Do not remove or defeat the ground prong on the AC Power Cord, as this constitutes a shock hazard. The Fuse Clip may be removed by first detaching the AC Power Cord, then prying the Fuse Clip out from above, using a flat-blade screwdriver in the notch provided. The Fuse Clip contains the standard fuse for the selected AC operational voltage. The standard fuse is held in the clip, and becomes the actual AC fuse when the Fuse Clip is installed. Voltage Selector Switch: For 115 VAC operation, slide to the left position toward 115V. 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 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). 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. 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. In situations with high ambient temperatures, particularly where multiple amplifiers are mounted in the same rack, it may be necessary to use fans to cool the rack. Best results are attained if the fans blow cool air in from the bottom of the rack, up through the amplifiers, expelling the heated air at the top. If the green LED indicator next to the power switch does not light when the power switch is turned on, turn the power switch off and check the AC power cord connections. If the power cord connections are complete, but the indicator still does not light, disconnect the EQ 28-8 AND EQ 282-8 from AC power and check the AC fuse. If the fuse needs to be replaced, use the same value and type fuse only. If no sound is heard, turn the level controls back to their original counter-clockwise position and check to confirm there is an input signal. Also check for proper wiring at all input and output connections, and verify that the cables being used are undamaged and are in good condition. [. . . ] If the EQ 28-8 AND EQ 282-8 is used in mono-bridge mode to drive a distributed speaker system, it is only necessary for the Channel 1 High-Pass Filter to be enabled. The EQ 28-8 AND EQ 282-8 is shipped from the factory with the High-Pass Filters disabled ("OUT"). 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). [. . . ]
