1. 12 A positive going pulse of greater than 250 msec is treated as a level sensitive trigger Shorter pulses are treated as a pulse sensitive trigger The minimum detectable pulse length is 200 usec During level sensitive operation applying a voltage to the trigger input will set the amplifier to the Operate mode When the applied voltage drops to zero the unit reverts to the low power consumption mode In the pulse sensitive mode a positive going pulse will toggle the amplifier between the low power consumption and Operate states duplicating the action of the right hand front panel button when it is held for three seconds The front panel button remains operative when the trigger input is used Therefore using the front panel button will put the amplifier out of sync with the trigger control device When used with level sensitive trigger operation the next trigger action will automatically restore sync However when using pulse sensitive trigger operation sync can only be restored by pressing the front panel button a second time Power Output Input Impedance XLR Input Polarity Gain Frequency Response Power Consumption Dimensions Weight Specifications 175 watts per channel continuous into 8 ohms 350 watts per channel continuous into 4 ohms 1 MQ unbalanced inputs 2 MQ balanced inputs 1 MQ per phase Pin 1 Ground Pin 2 Non inverting Positive Pin 3 Inverti2.
