GETTING TO KNOW YOUR CONSOLE

FACILITIES

	Refer to the fold-out front panel diagram at the rear of this
	manual, which shows the control functions on the SPIRIT
	Monitor. Each facility is described below, and is identified by
	a reference number.
	INPUT CHANNEL
1.	MICROPHONE INPUT
	The Microphone input is via a standard female XLR-3 connec-
	tor and is available when the LINE switch is released. It is
	designed to accept a wide range of balanced or unbalanced
	low impedance input signals.
	+48V Phantom Power is available on each input microphone
	socket, with an overall ON/OFF switch at the right hand side
	of the console, beside the power input socket.
	Transformer-coupled dynamic microphones may be used
	without causing damage, even when the +48V power is con-
	nected, but care must be taken when using unbalanced
	sources, because of the voltage present on pins 2 and 3 of the
	XLR connector.
	NOTE: The microphone should always be plugged in before
	switching the +48V on or off. Also you should be aware that
	some microphones draw an unusually large current which
	may overload the power supply, resulting in distortion. Con-
	sult your microphone supplier for guidance if necessary.
2.	INSERT
	The INSERT is a break point in the input channel signal path.
	It allows the signal to be taken out of the mixer, through an

external piece of equipment and then back into the mixer to continue through to the final output. The Insert is a 3-pole 1⁄4" ‘A’ gauge Jack, which is normally by-passed. When a jack plug is inserted, the signal path is broken at a point just after the Hi-Pass Filter, but before the EQ section. The signal from the channel appears on the TIP of the plug and is returned on the RING.
