TA-500
Setting higher gain does not change the maximum available power but changes the level of signal input to achieve maximum power. In any case, provided that the input signal is less than 20dBu/7.7V, the built in limiter circuit will prevent distortion within the amplifier.
The gain should be set to match the signal from the source, e.g. mixer, controller, or equaliser.
Attenuation & Gain Setting
The front panel gain controls allow precise level settings, and may be used to adjust the relative levels of sections of a large system, for example downfills or side seating cover in an arena.
The front panel gain controls are also useful when initially checking a system after it has been connected up.
Note that in BRIDGED mode only the Channel A control is active.
Output Connections
A Speakon NL4 connector is provided on each channel.
Damping Factor
The T series amplifier outputs provide a high damping factor, typically 400 times at low audio frequencies. This damping helps the amplifier to control the loudspeaker drive units, provided that the resistance of the intervening cables and connectors is very low. The sonic benefits of high damping factor are most pronounced at bass and
Amplifier damping factor is degraded by high resistance in the loudspeaker circuits; i.e. thin conductors, long output cable runs and tarnished, corroded or loose connections.
Damping factor is maximised by installing cables containing conductors of large cross- sectional area, and by specifying connectors with
