DIRECT This feature provides a variable strength signal output originating right from the output
transformer. Thus, good tone is supplied, all effects and Reverb are included, and there is absolutely
no loss of the Boogie's tone when "slaving" into another amplifier. If used for direct recording, bear in
mind that speakers themselves exert a tremendous coloration to the tone, primarily by rolling off the
highs very steeply above 5 to 6 kilohertz; thus, you'll want to approximate this effect with the EQ on
your mixing console. But most players will probably still prefer the recorded sound of a microphone
“listening” to the speaker.
In many sophisticated guitar rigs, players run their Direct output into their effects rack, and then
connect the outputs from the last effects unit into external power amplifiers. However, in such a
set-up, you cannot route the last effect unit back into the original Boogie. This would create a
feedback loop. Also note that a speaker or load resistor must remain plugged into one of the .22's
speaker jacks at all times, even when using the Direct output. Otherwise the amplifier will be
operating without a load, and damage will likely result. (Suggested value for a load resistor is 8-ohms,
25 watts minimum.)
EFFECTS SEND & RETURN These jacks provide a low-noise patch loop within the Studio .22's
preamp for connecting external effects units. Compatibility is quite good with most line-level effects
(although you may need to adjust the input level controls on some units to avoid overload).
Floor-pedal effects and "guitar processor" devices may not be compatible with your .22's Effects
Loop, as they are often designed to accept instrument-level signals rather than line-level. If such
units are used, they may need to be patched between the guitar and the amplifier input.
The Send jack can also be used as a "preamp output" without breaking the signal path that leads to
the .22's power section. If you're using the Send jack for this purpose and you want to hear the .22's
internal speaker, leave the Master turned up. If you don't want to hear the internal speaker, turn the
Master to zero.
The Effects Return on your .22 can also be used as an "auxiliary" line input for connecting an
external device, providing access to the .22's power section and speaker (and bypassing the preamp
section). Use the Master control to adjust the output level. The Graphic EQ (optional) and the
Presence control will also be active.
