REAR PANEL CONTROLS & FEATURES

REVERB:

These 4 rotary controls determine the dry/wet mix ratio for the rich analog REVERB and are wired to the Reverb return
circuit. Each of the 4 Channels have a dedicated control so that a different Reverb mix can be attained for each individual sound.
The controls sweep from a subtle background effect at their low range to a drenched, swimming effect at

The REVERB may be switched in and out of the circuit via the REVERB button on the Footcontroller.
NOTE: It is normal to experience approximately 1-2 seconds of delay before the REVERB is mixed with the dry signal after switching
the REVERB or Channels. This intentional built-in delay prevents both switching noise from the hard bypass relays used to isolate
the pure dry signal from the effected REVERB signal, and the prior Channels sound coming through the REVERB in the current
Channel when switching. At first this may seem strange, but after a couple minutes in real world situations you will see that it is prefer-
able to the embarrassing alternative of a loud overdriven crunch chord drowning out your beautiful clean passage in the middle of a
breakdown.

CHANNEL STRIPS:

These 4 clusters of switches and controls house the specific features that can be pre-assigned per individual
channel. Once you have deciphered one, you have learned the Kings' secret and are ready to rule, for they are simply repeated for
the 4 channels.

LINKAGE
This section is where you choose the status of LOOP 1 & 2, your choice of Speaker enclosure(s),
what type of Rectifier you wish to use and most importantly the power section you wish to com-
bine with your preamp choice with the PROGRESSIVE LINKAGE rotary control. Let's go over the
controls one at a time, beginning with this most important choice.

This 5 position rotary control contains the most powerful feature ever found on a self contained amplifier,
SIVE LINKAGE reaches maturity here in a multi-channel format that should make all serious guitarists
reconsider the very nature of channel switching amplifiers from here forward. By exploring the possibilities
of this awesome feature and understanding how to combine the front end preamp choices with a power
section that enhances that sound, you will be able to use the Road King to its full potential. The choices
are laid out in a logical left to right array with the lowest wattage settings to the left and the most powerful
RMS ratings to the right. On the Front Panel you will find the valuable PROGRESSIVE LINKAGE LED
status indicators, which keep you informed of your current power status at all times...even from across the
stage. Here is a one-dimensional description of the choices and their individual characters. one-dimensional one-dimensional description of the choices and their individual characters.
