Introduction Thank you for choosing a Performance Series power amplifier from Numark. These units are designed to provide a good combination of power, audio clarity, and reliable operation. The basic circuit has been kept as simple as possible to reduce the amount of components, thereby shortening the signal path, coloration and the chance of component failure. However, we opted to add what we regard as essential protection against overheating, short circuits and power on transients. An efficien

The SA5500 features detented gain controls will stay lit until the fault condition is rectified. with dB calibrations to simplify set up. The amplifier’s l

The XLR provide a good speaker speaker combination of ease of connection and resistance to corrosion. They are wired as per the following - convention: These are suitable for banana plugs, spade lugs or bare wires. Spade lugs and bare wires should both be screwed down tightly to exclude oxygen, and car

Audio Terms Gain Hum and Buzz This is the factor by which an input signal is amplified Hum typically is a lower pitched sound of around 50 or (increased) or attenuated (reduced) when passing through 60Hz, depending on the AC supply. If the hum or buzz an amplifier. Gain is generally measured in decibels (dB) is very loud, this is generally caused by bad connections which is a logarithmic ratio of input to output. Unity or - check cables and plugs for faults. zero gain means that the signal comes

The variable resistor is to ensure an impedance balance damping factor of 67. Increasing the cable length to 320ft between the positive and negative inputs, and should be of 8 gauge, the losses are 5% and the damping factor is adjusted until any hum is at a minimum. just 18.2. Balanced lines are also the most effective means of reducing or eliminating RF or ‘radio frequency Overload interference’. Long unbalanced cable runs are likely to It may seem an obvious point to make, but overloading pick
