CONTROLS: (Continued)A.C. MAINS: (power on)This switch delivers the A.C. power to your new Road King. Make sure the unit is grounded (all three terminals of the A.C. power cordmust be connected whenever possible to avoid injury to the user as well as to the unit) and that the proper voltage is present. Followthe cold start procedure described in the ON/ STANDBY section above when powering up yournew Road King.HI VOLTSONAC MAINSONNow that we have reviewed the Channels and their Modes we are ready to go aft and check out the treasure chest of features that ridethe Rear Panel.REST AREAPAGE 12

Perfect for using either the Road King head version orcombo as a master pre-amp and additional power amps for more power when needed. Some players use the SLAVE to derive an FXSend Signal and go to other amps for their wet sound.SPEAKERS4 OHM 4 OHMUSE WITH TWO 8 OHM CABSLEVELSLAVEOUTNOTE: Once a signal is taken from the SLAVE, it can not be inserted back into the FX Loop Return jack or afeedback loop will occur. Much like holding a microphone into a PA system’s cabinets...a loud high pitchedsqueal will be the result.HORTING PLUG IF NO SPKRS IN BSPEAKER OUTPUTS: Bank A & B - Cabinet SwitchingThese are the speaker output jacks and there are provisions for both 8 and 4 Ohm speaker loads. But as mentioned earlier, this is no8 OHMCOMBOSPEAKERS4 OHM 4 OHMUSE WITH TWO 8 OHM CABSCAUTION: USE SHORTING PLUG IF NO SPKRS IN BLEVELSLAVEOUTordinary amp…and these are no ordinary speaker outputs. The Road King takes the footswitchableindependent Channel concept a step further by providing two pre-assignable speaker outputs, enablingyou to use two different types of speaker cabinets with the same power section. They can even be ofdifferent impedance’s! For example you might want to use an open back cabinet with one type of speakersfor your clean CHANNELS 1 & 2, and switch to closed back cabinetry with a different type of speakersfor you lead work in CHANNELS 3 & 4. You can take this a step further and use both sets of jacksand combine them for a specific channel so that both open and closed back cabinets are on at once fora truly huge sound. These choices can be assigned per channel in the individual Channel Strips underSPKR A/B. Use any cabinetry you like as the Road King is not particularly sensitive to speaker impedance mismatches, other thandecreasing headroom slightly or making your power tubes work a little harder.However, It Is Extremely Important To Keep A Load On The Output Transformer At All Times! Failure To Do So Will Damage TheOutput Transformer And Void Your Warranty. For this reason we have included a Shorting Dummy Plug that we have attachedpermanently 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 theOutput Transformer.NOTE: Please make sure that the attached Shorting Jack is connected to the “B” SPEAKER OUTPUT jack at all times when not usingthe Cabinet Switching Feature.NOTE: You will experience a brief second when both speaker cabinets will be active during a cabinet switching sequence. This isnormal 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 brokenup, 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”.PAGE 13
