de Lisle Amp-Speaker Selector 4x4 with Reactive Attenuator

$999.00
The de Lisle Amp-Speaker 4x4 with Reactive Attenuator was designed to improve workflow in the studio by eliminating the need to re-cable amps and speaker cabinets. This version expands on our previous designs by incorporating a built-in reactive attenuator that can be used as a load box for silent recording along with a transformer isolated D.I.

Multiple functions are controlled by the Amplifier dial. Selecting positions 1-4 will:

• 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

Easily pair any of your amps with one of up to four connected cabinets by rotating the speaker switch. Should you need to roll back the SPL in the room, but keep your amp operating in the sweet spot, turn on the internal reactive attenuator. Attenuation is linearly variable from -6dB up to -22.5dB. Our unique design eliminates the need for impedance matching at the amp. Just connect your amp's 8 ohm output to the 4x4 Amp-Speaker Selector, then you can use any cab between 16 and 4 ohms.

Do you still want to be able to connect an Ox, Fryette Power Station or Boss Tube Amp Expander? No problem! The rear panel jacks allow you to insert an external attenuator which disconnects the internal reactive attenuator and D.I. functions.

With the hi-fi quality, transformer isolated D.I., you can go straight into your DAW and load up your favorite IRs. Use a TS cable for unbalanced or TRS for a balanced connection to your recording interface. The 4x4 Amp-Speaker Selector with Reactive Attenuator can also function as a reactive load box. Just flip the switch to disconnect the speaker and record silently.

The 4x4 Amp-Speaker Selector with Reactive Attenuator will quickly become mission control for your studio. Need help deciding which product is the best fit for you? Please feel free to reach out by phone or email. We're happy to help!

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.

    de Lisle Amp-Speaker Selector V2

    $289.00
    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.

    $199.00
    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.
