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.

The de Lisle Amp-Speaker Selector V3 was designed as a studio tool to conveniently route the output of up to three amplifiers to various speaker cabinets. This version features a loop to allow a single attenuator or similar device to be easily shared between any combination of the amps and speakers.

Just connect your amps' outputs to numbered amplifier inputs on the rear panel. Then, hook up your speaker cabinets. Routing the signals is simple: the three Speaker switches on the front panel correspond to the three speaker connections. The 0-3 positions of each bank match that speaker cabinet to an amplifier (or 0 for not connected).

Connect your attenuator's input to the Send jack and its output to the Return jack. Use the front panel Send knob to connect the attenuator to any of the amps' outputs. Then, set one or more of the Speaker knobs to the return arrow icon (position 5).

Use multiple amps at the same time, swap speaker cabinets between amps, share a single attenuator or connect multiple speakers to an amp in parallel. Signal and ground connections from the amps are always isolated from one another. And as a precaution, the unused amps see a load.

The de Lisle Amp-Speaker Selector V2 was designed as a studio tool to conveniently route the output of up to four amplifiers to various speaker cabinets. Just connect your amps' outputs to numbered amplifier inputs on the rear panel. Then, hook up your speaker cabinets. Routing the signals is simple: the four switches on the front panel correspond to the four speaker connections. The 0-4 positions of each bank match that speaker cabinet to an amplifier (or 0 for not connected). Use multiple amps at the same time, swap speaker cabinets between amps, or connect multiple speakers to an amp in parallel. Signal and ground connections from the amps are always isolated from one another. And as a precaution, the unused amps see a load.

The de Lisle FX Loop Router allows you to effortlessly share your FX between up to 8 amps.

Plug your FX into the rear panel FX Input and FX Output jacks. Then rotate the Amplifier dial to route your FX to any of the connected amp loops. Unused amps are placed in bypass mode to prevent noise. We've also included a front panel Bypass switch for the selected amp and a Ground switch to help eliminate noise.

The FX Loop Router runs off a standard 2.1mm/5.5mm center negative 9V supply (included). We've also provided a "daisy chain" extension jack, so you can connect external 9VDC powered devices.

The de Lisle Amp-Speaker Selector 7x7 with Attenuator Loop was designed as a studio tool to conveniently route the output of up to seven tube amplifiers to various speaker cabinets. This version features a loop to allow a single attenuator or similar device to be easily shared between any combination of the amps and speakers.

Just connect your amps' outputs to numbered amplifier inputs on the rear panel. Then, hook up your speaker cabinets. Routing the signals is simple: the seven Speaker switches on the front panel correspond to the seven speaker connections. The 0-7 positions of each bank match that speaker cabinet to an amplifier (or 0 for not connected).

Connect your attenuator's input to the Send jack and its output to the Return jack. Use the front panel Send knob to connect the attenuator to any of the amps' outputs. Then, set one or more of the Speaker knobs to the return arrow icon (position 9).

Use multiple amps at the same time, swap speaker cabinets between amps, share a single attenuator or connect multiple speakers to an amp in parallel. As a precaution, the unused amps see a load.

The de Lisle Amp-Speaker Selector 8 x8 was designed as a studio tool to conveniently route the output of up to eight tube amplifiers to various speaker cabinets.

Just connect your amps' outputs to numbered amplifier inputs on the rear panel. Then, hook up your speaker cabinets. Routing the signals is simple: the eight Speaker switches on the front panel correspond to the eight speaker connections. The 0-8 positions of each bank match that speaker cabinet to an amplifier (or 0 for not connected).

Use multiple amps at the same time, swap speaker cabinets between amps, or connect multiple speakers to an amp in parallel. Signal connections from the amps are always isolated from one another. And as a precaution, the unused amps see a load.

The de Lisle Amp-Speaker 4x4 Deluxe was designed to improve workflow in the studio by eliminating the need to re-cable amps and cabs. This version expands on our previous designs by incorporating simultaneous input switching and a bypassable attenuator loop.

Plug in your guitar / pedalboard and send it to any of the 4 connected amps by rotating the Amplifier dial. The amp's output is then sent to the selected speaker cabinet. We've also included an attenuator loop that allows you to easily connect your Ox, Fryette, etc. to any combination of amplifier and cabinet.

The 4x4 Deluxe runs off a 2.1mm/5.5mm center negative 12V supply, which is boosted internally for increased signal headroom. Amplifier inputs are transformer isolated to prevent ground loops. Unused amps are muted at the input and switched to a protective load.

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.

The de Lisle Pre-Amp Selector was designed to improve workflow in the studio by eliminating the need to re-cable when switching between numerous preamps and power amps.

Plug in your guitar / pedalboard and send it to any of the 4 connected preamps (or modelers) by rotating the Preamp dial. The preamp's output is then sent to the selected Power Amp. Alternatively, one could connect any line level device to the rear panel Power Amp Input jacks. So, one could be assigned to a power amp, another to a recording interface, external FX, etc. There is also an FX loop between the Preamp and Power Amp which can be bypassed on the front panel.

The Preamp Selector runs off a standard 2.1mm/5.5mm center negative 9VDC supply, which is boosted internally for increased signal headroom. Preamp inputs are transformer isolated to prevent ground loops. Unused preamps are muted at their input.

The de Lisle Preamp Power Amp Selector was designed to improve workflow in the studio by eliminating the need to re-cable when switching between numerous preamps and power amps.
