FX LOOP: SEND / RETURN:

These two 1/4" jacks are thae patch point for external effects. The Effects Loop is wired in parallel with the normal signal. Connect the SEND jack to your Effects Input jack. Connect the RETURN jack to the Output jack of your effect. The Effects Loop is a patch point between the pre-amp and power section. Therefore, the RETURN jack can double as a “Power

1.25A	RHY	Amp Input” jack.

When the RETURN jack is used as an input, only the 5 Band EQ, the PRESENCE control of the active channel and the OUTPUT LEVEL control are being utilized, all other controls are inactive.

FX MIX:

This control determines the dry/wet blend of the FX Loop signal in relation to the unaffected signal. Set to 0% you will experience only the dry signal (no effect) and at a setting of 100% the entire signal will be wet (total effect.)

For the best results...Set the mix of your effect to 100% wet. Then dial in the amount of effect that you wish to hear, starting at 0% with the FX Loop Mix Control. The drier (closer to 0%) signal you use, the better your tone should be. This is one of the advantages in having a parallel type FX Loop designed into your DC-3amplifier...this circuit allows the amplifier to retain its purity with the least possible degredation due to effects impedance mismatching.

RECORDING:

This jack provides direct-to-console interfacing for recording or sound reinforcement applications. It is a circuit dedicated to reproduc- ing the roll off that occurs in the output section with a speaker connected. With accuracy, it faithfully captures the DC-3’ssoulful

character.

The send level strength is determined by the GAIN and MASTER Controls. From the Recording jack, adequate signal level will be available for most of your recording needs and live performances.

SILENT RECORDING:

This rocker switch which is located down under the chassis and selects between the live “Speaker On” setting and the silent “Speaker Mute” setting. This is a perfect solution for all-nighters! This switch mutes all of the signal at the power section driver s tage, removing

the need for a speaker load IN THIS POSITION ONLY!

NOTE: When this switch is set to the “ON” position, a speaker load must be maintained by either a load resistor of some type or a speaker itself. Failure to comply with this instruction could result in major damage to the amplifier. Leave your speaker connected.
