SLAVE:

This 1/4" jack and control provide a signal derived from the speaker jack. Perfect for using either the Road King head
version or combo as a master pre-amp and additional power amps for more power when needed. Some players use the SLAVE to
derive an FX Send Signal and go to other amps for their wet sound.

NOTE: Once a signal is taken from the SLAVE, it can not be inserted back into the FX Loop Return jack or
a feedback loop will occur. Much like holding a microphone into a PA system's cabinets...a loud high pitched

However, It Is Extremely Important To Keep A Load On The Output Transformer At All Times! Failure To Do So Will Damage
The Output Transformer And Void Your Warranty. For this reason we have included a Shorting Dummy Plug that we have attached
permanently to the chassis to prevent accidental "no load" scenarios. We ship this shorting jack connected the "B" SPEAKER OUT-
PUT so that if a channel is selected that is assigned to either the "B" or "A & B" OUTPUT choices, there will still be a load on the
Output Transformer.
NOTE: Please make sure that the attached Shorting Jack is connected to the "B" SPEAKER OUTPUT jack at all times when not
using the Cabinet Switching Feature.
NOTE: You will experience a brief second when both speaker cabinets will be active during a cabinet switching sequence.This is nor-
mal and necessary to protect the output transformer from damage due a possible "no load" scenario during the instant of switching.
NOTE: If you switch to a Channel when not using the Cabinet Switching Feature and experience low output combined with a broken
up, distorted signal, or no output at all, check that Channels' SPEAKER ASSIGN mini toggle to be sure that it is not set to SPKR "A
+ B" or "B".
NOTE: Do not use the SPKR A + B selection when two 8 Ohm cabinets are each connected to the two 4 Ohm OUTPUTS of each
Speaker Output Bank. A 2 Ohm load puts an excessive strain on the power tubes causing them to wear unusually fast.

example you might want to use an open back cabinet with one type of speakers for your clean CHAN-
NELS 1 & 2, and switch to closed back cabinetry with a different type of speakers for you lead work in
CHANNELS 3 & 4. You can take this a step further and use both sets of jacks and combine them for
a specific channel so that both open and closed back cabinets are on at once for a truly huge sound.
These choices can be assigned per channel in the individual Channel Strips under SPKR A/B. Use any
cabinetry you like as the Road King is not particularly sensitive to speaker impedance mismatches,
other than decreasing headroom slightly or making your power tubes work a little harder.
