Turbosound TA-500DP Benutzerhandbuch

 

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. 

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. 

 

A Speakon NL4 connector is provided on each channel. 

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 low-midrange frequencies 
(i.e. 10 to 600Hz) providing a subjectively tighter sound as a result of the improved 
reproduction of transients. 

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 heavy-duty contacts and waterproof 
covers. The cable sets supplied with Aspect systems are manufactured to a high specification 
with these considerations in mind.
