USING THE FX RETURN AS A POWER AMP INPUT: (Continued)
NOTE: When using the Roadster’s EFFECTS RETURN jack as a Power Amp Input, the input sensitivity will be most “normal” in
CHANNELS 1 and 2. For increased power sensitivity you may choose the incredibly sensitive CHANNEL 3 or 4 MODERN mode.
This will increase the power section input sensitivity by an order of ten. Be warned, this will make the OUTPUT level control extremely
sensitive and the amplifier will be LOUD!
NOTE: See the section on OUTPUT in the CONTROLS section earlier in this manual for more information on using the Roadster
as power amp only.
EXTERNAL SWITCHING:
These seven jacks are provided so that you may control the 4 Channels, the EFFECTS LOOP, The
Reverb and the SOLO feature with an external master Switching device. This is essential to use the Roadster as part of a Midi rig
where all sounds are called up via a Midi Footcontroller and both amplifier and effects settings are stored under a midi program
number. The logic used to trigger these ports is simple tip-to-ground, latching type and most
Master switching systems incorporate several jacks dedicated to this logic.
The EXTERNAL SWITCHING jacks override the Roadster’s Footcontroller. Once a Chan-
nel or Feature has been triggered “On” at the EXT. Switch ports, it may not be controlled or
turned “Off” until the logic at the Switch Port is reversed.
TUNER OUT:
This jack located in the stack of EXTERNAL SWITCH ports (see above) is a Tuner Output and allows for silent tuning
in live stage or studio environments where it is essential to tune your instrument without sound. When a Tuner is connected to this
jack, tap TUNER MUTE on the Footcontroller and the signal to the speakers will be muted. The signal will remain muted until you tap
TUNER MUTE again to bring the signal back.
NOTE: The FX LOOP switch must be set to LOOP SYSTEM IN for the TUNER MUTE function of the Footcontroller to work properly.
A.C. RECEPTACLE:
The removable “Euro” Style” A.C. cord that is supplied with your new Roadster makes set-ups and tear-
downs after the gig a snap. It also makes de-racking much easier when you wish to remove the unit from a hard wired rack system
where all the A.C. cords have been cable-tied in. Additional heavy duty cords are available should you ever
need one...simply call us direct and we can ship one directly to you for a nominal charge, plus shipping cost.
Make sure the A.C. cord is firmly seated in the A.C. RECEPTACLE found on the tube side of the chassis before
powering up the amplifier.
NOTE: Never alter the three prong power cord in any way.
