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 550x
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 550x, 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 550x 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 550x is now a power amp
only.
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 adaptor 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 volume control of your CD (or other) audio source. The mixed sound will be heard
through your speakers. 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 550x comes equipped with the capability for hands-free control of the SubWave™ effect. To achieve this function, locate
the footswitch and 25-foot 1/4"-to-1/4" instrument cable included in your 550x packaging. Connect one end of the cable to
the output jack on the footswitch, and connect the other end to the SubWave™ Footswitch jack on the rear of your 550x. 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.
A few notes: The type of switch contained inside the footswitch chassis is momentary, normally open. Also, if you connect the
footswitch to the unit while the unit is on, the SubWave effect may engage. This is normal.
SPEAKER OUTPUTS MODE SWITCH
Setting the Speaker Outputs Mode Switch up to the "On" position allows the signal from the amplifier to be heard through any
speaker enclosure(s) connected to the Speaker Output section of the 550x. Setting this switch down to the "Off" position dis-
ables the speaker output section. This feature allows you to:
