Custom Audio Electronics 3+SE Tube Preamp Operating Manual Download Page 4

Worldwide Voltage Selector,

Fuse Holder and Power Switch

For optional 3+SE Footswitch

Controller Only

Switched via on/off switch or contact

closure of 25ohm to ground or better,

such as Custom Audio Electronics 4x4

or 2x4 Audio Controller, Rocktron/

Bradshaw switching systems, Rocktron

Patchmate or Rockman Octopus.

When channel 2 or channel 3 are not

switched, channel 1 is the default.

*Note, even though no harm will be done,

since channels 2 and 3 are out of phase

with each other, it is not recommended
to have them both on at the same time.

Outputs are designed to drive line level equipment. Set effects

for +4db or 0db, not -10db or -15db! Output impedance is better

than 1K, and is designed to drive a total load of 10K or higher.

The MAIN out should normally be used. The GND.LIFTED out is

provided to help solve ground loop problems in complex systems.

The AUX.IN has a 1Meg ohm input

impedance. The front panel has

priority over the rear panel AUX.IN
