CONNECTING AN EXTERNAL EFFECTS DEVICE TO THE BLACK BEAUTY EFFECTS LOOP
Obtain two high-quality shielded patch cables, preferably as short as possible. Route them in the most direct way possible. (Running
patch cables over the top of the Black Beauty—as with any amplifier—can induce hum in the cables and is not recommended.) Take
one cable and connect it from the Effects Send jack on the Black Beauty to the input of your external effects device. Take the second
cable and connect it from the output of your external effects device to the Effects Return jack on your Black Beauty. To set levels, fol-
low the instructions as previously listed in the "Effects Blend Control" heading under "Front Panel Features."
And, just so there isn't any confusion, the Effects Loop has nothing to do with the SubWave™ effect onboard your Black Beauty. It
only is used in conjunction with an external effects device.
EFFECTS SEND
This jack's primary function is to send a post-EQ-and-SubWave™ signal to an external effects device for use in the Black Beauty
Effects Loop. However, it can also be used as:
1. A line level output for use in conjunction with an additional (slave) power amp—such as SWR's Power 750.
2. An unbalanced output suitable for recording or live mixing board purposes. The output impedance of the Effects Send jack is
100 Ohms.
EFFECTS RECEIVE
This jack's primary function is to complete the Effects Loop circuit by routing the post-external-effects device signal back into the
power amp of the Black Beauty, where it can be blended back in with the original signal by using the Effects Blend control on the
front panel. However, it can also be used as:
1. A power amp input jack. If, for some reason, you wished to bypass the entire front end and use the Black Beauty strictly as a
power amp, you could take the output of whatever line-level audio source you wished and connect it to this jack. Then, set the
Effects Blend control to the full clockwise ("WET") position. Use the Master control to set the overall level, and your Black Beauty is
now a powered speaker cabinet.
2. An input for pre-recorded music, for playing along and practicing purposes. To accomplish this, insert a CD player or other
sound source into the Effects Receive jack. (It must be a MONO 1/4" plug that goes into this input, so you'll have to use a stereo-
to-mono cable adapter of some kind.) You can adjust the level of recorded music versus the "live" sound of your instrument by
using both the Effects Blend control (the more clockwise the control, the more pre-recorded music signal you'll hear) and the vol-
ume control of your CD (or other) audio source. The mixed sound will be heard through your speaker(s). Besides pre-recorded
music, this is also an excellent way to practice along with a drum machine.
Input impedance of the Receive jack is 27k Ohms minimum.
Note: Inserting a plug into the Effects Receive jack activates the Effects Blend control. The control receives this command
through the ground created by the phone plug making contact with the jack. The plug must be a mono plug (tip and ground). If
you have a stereo plug only, it will be necessary to tie the ring and the ground together.
SubWave™ ACTIVATOR FOOTSWITCH
Your Black Beauty comes equipped with the capability for hands-free control of the SubWave™ effect. To achieve this function, locate
the footswitch included in your Black Beauty packaging. Connect the cable to the SubWave™ Footswitch jack on the rear of your
Black Beauty. Turn the effect on and off by stepping on the switch; the illuminated switch above the SubWave™ Level control on the
front panel should alternate on (blue) and off, and the effect should engage and disengage accordingly.
Note: The type of switch contained inside the footswitch chassis is momentary, normally open. If you connect the footswitch to
the unit while the unit is on, the SubWave effect may engage. This is normal.
