DI OUTPUT
This 1/4" stereo jack socket is used to connect the amplifier to a low impedance, balanced input on a PA system
or recording mixer. The signal can be taken PRE or POST EQ (see above), ie with or without the tone shaping
added by the EQ section of the amplifier.
On the CTm30 the DI is derived directly from the output transformer and therefore is an exact copy of the sound
that you here.
SPEAKER OUTPUTS
There are dedicated Speakon connectors for 2, 4 and 8! load speaker cabinet configurations. It is important
that the correct output or outputs are used to match the impedance load of your cabinets. Please refer to the
diagrams later in this manual.
CTm 30,and 15 are fitted with jack outlets at 8 and 4 ohms.
OFF/PREHEAT
Use this switch to pre-heat the valves, bringing them up to the correct operating temperature before
performing.
STANDBy/FULL
No signal is sent to the speakers when this switch is in the STANDBy position. Switch to FULL when you are ready
to perform.
