(17) GROUND LIFT
This disconnects the ground connection from Pin1 on the DIRECT OUTPUT connector. Usually it should be
left in the GND position, but in certain circumstances hum is produced when connecting to another device
due to grounding differences. Lifting the ground connection should eliminate the problem.
(18) PREAMP OUT/POWER AMP IN
The preamp out is the signal coming from the front panel. The power amp input is a direct connection to the
power amplifier. An external processor or volume pedal can be inserted between the preamp and the power
amp if needed. Inserting a jack into the preamp output disconnects the power amp input; inserting a jack
into the power amp input also disconnects the preamp from the power amp. To use the TE1200 as a power
amplifier only, apply the signal to the power amp input. This loop is after the OUTPUT Level knob.
(19)EFX LEVEL
Some effect units are designed for lower input levels. When pressed, this switch lowers levels to prevent
distortion.
(20)EFX SEND/RETURN
These two connectors are provided for patching an external effects processor (delay, chorus etc.) in series with
the preamp signal. The signal level is set by the EFX level switch. The effects loop can be turned on and off with
the footswitch. This loop is before the OUTPUT Level knob.
(21) SPEAKER OUTPUT CONNECTORS
This is the amplifier output, with two paralleled connectors. These connect to the speaker cabinets. The
minimum load for the amplifier is 4 Ohms. This can be a single 4 Ohm cabinet, two 8 Ohm cabinets, or any
combination of cabinets whose parallel combination is greater than 4 Ohms, total. The output is a bridged
signal – both lines are driven. Do not ground either one or the unit will shut down and damage may occur.
There can be high peak voltages on these connectors.
(22) FUSE
Use only the properly rated fuse for your line voltage.
(23) VOLTAGE SELECTOR SWITCH
Set this to your local mains voltage. An incorrect setting can damage the unit. The fuse's rating must
match the mains voltage setting.
(24) POWER
Applies power to the unit.
(25) MAINS INPUT
This is the receptacle for an IEC line cord, which provides AC power to the unit. Connect the line cord
to this connector to provide power to the unit. Make sure the voltage setting and fuse are correct before
turning on the unit.
Never break off the ground pin on any equipment. It is provided for your safety. If the outlet used does not
have a ground pin, a suitable grounding adapter should be used, and the third wire should be grounded
properly. To prevent the risk of shock or fire hazard, always make sure that the amplifier and all associated
equipment is properly grounded.
