(17) GROUND LIFT
is disconnects the ground connection from Pin1 on the DIRECT OUTPUT connector. Usually it should be
le in the GND position, but in certain circumstances hum is produced when connecting to another device
due to grounding dierences. Liing the ground connection should eliminate the problem.
(18) PREAMP OUT/POWER AMP IN
e preamp out is the signal coming from the front panel. e power amp input is a direct connection to the
power amplier. 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
amplier only, apply the signal to the power amp input. is loop is aer the OUTPUT Level knob.
(19)EFX LEVEL
Some eect units are designed for lower input levels. When pressed, this switch lowers levels to prevent
distortion.
(20)EFX SEND/RETURN
ese two connectors are provided for patching an external eects processor (delay, chorus etc.) in series with
the preamp signal. e signal level is set by the EFX level switch. e eects loop can be turned on and o with
the footswitch. is loop is before the OUTPUT Level knob.
(21) SPEAKER OUTPUT CONNECTORS
is is the amplier output, with two paralleled connectors. ese connect to the speaker cabinets. e
minimum load for the amplier is 4 Ohms. is 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. e output is a bridged
signal – both lines are driven. Do not ground either one or the unit will shut down and damage may occur.
ere 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. e fuse’s rating must
match the mains voltage setting.
(24) POWER
Applies power to the unit.
(25) MAINS INPUT
is 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 o 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 re hazard, always make sure that the amplier and all associated
equipment is properly grounded.
