REAR PANEL FACILITIES

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.
