The de Lisle Amp-Speaker 4x4 Pro was designed to improve workflow in the studio by eliminating the need to re-cable amps, fx and cabs. This version expands on our previous designs by incorporating simultaneous input switching, fx loop switching and an attenuator loop.
Turning the front panel Amplifier dial will do the following:
• Route the guitar input to the selected amp's input
• Send the amp's output to the selected speaker
• Mute all unused amps at their input
• Switch unused amps to a load
• Route the Pedalboard In / Out to the active amp's FX send and return jacks
• Place unused amp FX loops in bypass
When activated, the attenuator follows the selected amp and cabinet, so you can easily connect your Ox, Fryette, etc. to any combination of amplifier and cabinet. Should you prefer to go straight from amp to cabinet, just place the Attenuator switch in the down position to bypass the attenuator loop. Similarly, the active amp's FX loop can be bypassed by placing the FX Loop switch in the down position.
The 4x4 Pro runs off a 2.1mm/5.5mm center negative 12V supply, which is boosted internally for increased signal headroom. Amplifiers are transformer isolated to prevent ground loops.
Patent Pending.
New features for 2024 models:
There are now three options for amp input switching. DIRECT takes the front panel input and sends it directly to the input of the selected amp, bypassing any additional circuitry. This is the position for normal use. ISO, for ISOLATED, sends the input signal through an isolation transformer. This can be used to eliminate ground loops or when a low impedance output is desired. When the ground switch is in the left position, the isolation transformer is bypassed entirely and an op-amp buffer provides a low impedance output.
