The de Lisle Amp-Speaker Selector (Version 1) was designed as a studio tool to conveniently route the output from any of the connected amplifiers to an isolation cabinet. Alternatively, a single amplifier can be paired with one of up to three individual cabinets. Signal and ground connections from the amps are isolated, and as a precaution, the unused amps see a load. Similarly, when used as a cabinet selector, jacks with no cable inserted will be switched to an internal load. So, one can use a single cabinet or two cabinets without worrying about switching to an open cabinet jack.

The de Lisle Speaker Cabinet AB Selector Switch allows you to toggle between two speaker cabinets connected to the same amp. If your amplifier has multiple output jacks for different impedance cabinets, you can connect a second output to the ALT Z jack and toggle between two cabinets connected to different impedance outputs on the same amp. There's also a remote input that will allow you to operate the switch from a distance with a simple TS latching switch.

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.

The de Lisle Amp-Speaker 8x6 Pro Plus 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, an attenuator loop, dual speaker mode and a variable line out for going direct into a DAW for use with IRs or cab simulators.

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 8x6 Pro Plus 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.
