Rear Panel Connections
t. 3 Pin IEC llains Power lnlet: the operaring volrage is 240 vAC @50Hzot ll0 vAC @ 60 Hz. The AC power
voltage lcvel is not cxlemally user adjustable but is facrory pre-set at 240VAC. The inlct is equipped with an inbuilt AC fusc
holder fitted wilh a I amp fuse plus a s;nre. found within the holder. pou€r consumption is 50VA.
t Please ensure that the mains power cord is disconnected before attempting to ch€ck or r€place this fuse.
2. Direct Output Terminal Strip: rnese screw terminals allow access to rhe direct outpurs of the amplifier. Spnre
screw terminals allow for the conncction ofvarious tone module accessories. Reading from left to right the rerminals are-

+Charutels 2 and 3 are muted when these two terminals are shorted together onlv when the TX30l0 mute module is fitted.
Note: The minimum impedance at any lime on maximum load for 100 Volt line should be no less than 330 Ohms for the IC30.
3 Tape O utput: RCA style phono output connector for tine level output. Provides a maximum of 350mv into loK Ohms,
ideal for a connection to most standard ape recorden. This output is sourced before the master gain control and as such, the
tape output level is not inlluenced by the operation of the master gain control.
4 Univergal Microphone/Line lnputs: with an input sensirivity of l.5mv@ 200 ohms, pin connections for XLR
balanced microphone input connectors are: pin #l -earth; pin #2-active (high, +): pin #3-active (low, -). The RCA socket line
level input connectors havc an input sensitivit-y of 80mV @ 47K ohms. Reading from left to right actoss the rear lnnel- the
connection are for the inputs 3, 2, & I respectively. All three inputs can be used for microphone and autliary input sources. It
is also possible to connect both microphone and au\iliary inputs to one channel simultaneously. however their relative levels to
one another will be fixed, as there is one gain control for each channel on the front panel.
