When you first receive youramplilier il may not have an appropriate plug is used and coresponds with the amplifier's current (ampere) requirements and meets the approval of your local energy authority. Please refer termination of this lead to qualified personnel.

' Operation 13 4. Operation IMPORTANT All signal source equipment should be adequately earthed. This not only ensures your safety but everybody else's as well. Faults can and do occur in mains connected equipment where the chassis can become "live" if it is not properly earthed. ln these inslancesthe fault in a "floating'(un-grounded) piece of equipment will look for the shortest path to ground which could possibly be your amplifiefs input.
l4 Operation Each channel of your amplifier has a nominal balanced input impedance of 2SkOhms (@1kHz) and should not present a difficult load forany signal source. Yoursignal source (i.e. the equipment feeding the amplifier) should have an output impedance of 600 Ohms orlowerto avoid unwanted high frequency loss in the cabling. produces a voltage drop due to thewire's resistance.
Bridge Mode 15 2. 5. Bridge Mode The term BRIDGE is used when two independent amplifier channels are used to drive the same load. The load is in series (a bridge) between the two amplifier channels. Channel A is used as the "dominanl" channel and its output is in phase with the inpul signal, and channel B has to have its phase reversed so it is exactly 1800 out of phase with the input signal. Loop from Channel-A male XLR to Channel-B female inputXLRwith a Reverse Phase Lead.

Though this method is in line with the variousslandardsthat exist, it only gives an indication tothe maximum voltage s,wing (before clipping) for a given load.
Maintenance 17 T.Maintenance Your AM3002 amplifier will need minimal maintenance. No internal adjustments need to be made to lhe unit to maintain optimum performance. To provide years ofunhindered operation we suggest a maintenance inspection be carried out on a regular basis, say every 12 months or so. Fans Due to the openness of the air path through your AM3O02 amplifier, very little dust should settle within the amplifier.
