Randall KH103, Operation Manual

Page: 4 / 8

MIDI Programmable Functions & Masters: !
Channel 1 overall voicing is American 60's era. Channels 2 overall voicing is early Metallica with a heavy dose of thick midrange. Channels 3 overall voicing is 90's+ modern
voicing, Black album and beyond with more growl, gain, and sparkle.
BOOST: A preset gain boost for all channels. BOOST function works in all modes of Channel 1. BOOST button will light but will not function in channels 2 and 3 only in the
VOICING L mode.
VOICING L: For Channel 1, there is always 3 stages of tube gain to keep the harmonic content, voicing L scoops out the mids. For Channels 2 & 3, it selects 2 preamp gain
stages. This is excellent for players that love that wide open, late 60’s vibe. This is the lowest gain setting of the KH103. The BOOST switch is inactive in this mode. With the
GAIN control setting at 11 o’clock and lower, in conjunction with MASTER volume set beyond 2 o’clock, will give you some stellar clean tones with loads of dynamics. The 3 way
BRIGHT switch engages a treble boost and the amount is dependent on the GAIN control setting. Higher settings of the GAIN control, less effect the BRIGHT switch will have
and the opposite with lower GAIN control settings. For a great plexi type of tone, set the MASTER completely open in the clockwise position, set the GAIN control at 2 o’clock,
BRIGHT switch ON, tone stack as desired, Depth off and Presence at 1 o’clock.
VOICING M: For Channel 1, there is always 3 stages of tube gain to keep the harmonic content, voicing M bumps up the mids. For Channels 2 & 3, it selects 3 preamp gain
stages. This setting gets into some overdriven tone while still remaining very open sounding. Placing the BOOST switch ON adds more gain and girth to the tone. The 3 way
BRIGHT switch functions the same as described above but now with the added tube stage, the upper harmonic quality has shifted. Varying the GAIN control will give you
different degrees of attack and sharpness to the tone. Place the BRIGHT switch center off and the tone gets rounder and warmer sounding that stays even with the movement of
the GAIN control. Higher settings of the GAIN control will give you more distortion and sustain. It will have enough gain for most lead work with a nice balance of punchy
percussiveness. This setting also cleans up nicely when you roll back your guitar’s volume.
VOICING H: For Channel 1, there is always 3 stages of tube gain to keep the harmonic content, voicing H bumps up the mids as well as gain. For Channels 2 & 3, it selects 4
preamp gain stages. This setting gets you into the soaring modern high gain tones. Placing the BOOST switch on adds even more gain and thickness. The 3 way BRIGHT switch
adds the cut and teeth to the tone and as stated above, is dependent on the GAIN control setting. Higher settings of the GAIN control with the BOOST and BRIGHT switch ON,
will bring in a singing lead tone with the perfect balance of compression without losing note definition.
FX: Engages FX Loop 1 on the back panel. Loop 2 is not active.
LOOP 2: FX and LOOP 2 button must be selected to engage FX Loop 2 on the back panel. Loop 1 is not active.
MASTER 2: Master 1 is the default overall Master. MASTER 2 engages the 2nd Master Volume.
STORE: After a MIDI PC or CC has been sent to the MIDI IN jack via a controller or other MIDI device.
Push and hold down the STORE button until it blinks 3 times to store all of your changes.
STANDBY: Breaks the output tubes cathodes only. Preamp and Loops are still functioning.
POWER: On/off for the mains!
