The DualKlonz is a two-channel amplifier. Switching between channels can be 
operated via the Channel switch on the front panel, or via the footswitch.

Modern Channel:

This channel is optimized for High Gain tones. The gain is controlled by the G1 
and G2 knobs. These are part of two cascaded preamp stages. The output of G1 
stage goes to the input of the G2 Stage. Think of it as a boost pedal (G1) going 
into the input (G2) of an amp.

The selection of different Modern models is done through the app or MIDI control 
(Please refer to the help file embedded into the app for full features and details.)

This second G2 stage is also bypassed when selecting low-gain models from the 
app or MIDI control. In this case the LOW GAIN footswitch won

t be active.

Adjust the Bass, Mid, and Treble controls to taste. Adjust the Vo: Master Volume 
control for Modern Preamp for the required output level.

Typical setup and Cable Connections

Connect a speaker cab to Speaker outputs, following the Cab

s specified 

impedance. If only one cab is used, always connect it to the “A” outputs. Only If 
a second cab is used, connect it to the “B” outputs. If you use two cabs, a 
footswitch must be connected to the CAB SW input. If no footswitch is connected, 
only the “A” output will be active. 
(

IMPORTANT NOTE: 

When you are using different types of power tubes, the 

output impedances may change. Please pay attention to the back panel to find 
out which output to use.)

If used, connect your effects input to the Send output Jack, and the effects output 
to the Return input Jack. If necessary, adjust the Level control to adapt the Send 
output level to the effects input sensitivity. Typical setting is to adjust the Level 
control to STANDARD.

If you use two cabs, a footswitch must be connected to the CAB SW input. If no 
footswitch is connected, only the “A” output will be active. When connecting 
the footswitch, please put the Cabinet switch plug with “CAB” mark in the 
Channel switch Jack, and Channel switch plug with “CHA” mark in the Channel 
footswitch Jack, then the Channel switch of the front panel is excluded.

Please make sure that Mains Voltage Selector for 110-120V and 220V-240V input 
AC matches your local mains voltage. Check that both On/Off and STANDBY 
switches on the amplifier right side are both in OFF position, connect the mains 
cable. Turn on the Power switch. Allow at least 2 minutes for the tubes to warm up. 
Connect your instrument to the guitar input jack on amplifier left side, and turn 
down the Vo: Master Volume control for Modern Preamp and Vo: Master Volume 
control for Vintage Preamp to the minimum. Turn on the STANDBY switch and 
complete cable connections.
