de Lisle Amp-Speaker Selector 8×8 Amplifier Speaker Cabinet Signal Router Switcher with Reactive Attenuator IR Loader

The de Lisle Amp-Speaker Selector 8x8 with Reactive Attenuator IR Loader 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 impulse response output.

The front panel includes an input for your guitar or pedal followed by a three position power switch; off, direct and isolated. The direct setting takes the front panel input and sends it straight to the amp. Iso employs an transformer isolation to prevent any potential ground loops. Engaging the ground switch while in Iso mode bypasses the transformer while still offering a low impedance buffered output to the amp. Multiple functions are controlled by the Amplifier dial. Selecting positions 1-8 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 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 IR functions.

The Hi-Fi quality, transformer isolated IR Out allows you to go straight into your DAW to load up your favorite IRs or use one of our 10 included impulse responses for a variety of high quality cabs sims.

Included Impulse Responses (See "Sounds" tab below):

01 Vox AC30
02 Marshall 1960AV
03 Marshall 2550
04 Orange PPC
05 Celestion Vintage 30
06 Tweed Bassman
07 Tweed Champ
08 Blackface Twin
09 Mesa Rectifier
10 Ampeg SVT
11 Bypass

Use a TS cable for unbalanced or TRS for a balanced connection to your recording interface. The 8x8 Amp-Speaker Selector with Reactive Attenuator IR Loader can also function as a reactive load box. Just flip the switch to disconnect the speaker and record silently.

The 8x8 Amp-Speaker Selector with Reactive Attenuator IR Loader 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!
