8X7 Amp Cabinet Switcher
Control up to 8 amplifiers, 7 speaker cabinets, one power attenuator and your FX-Loops from a single switching system.
Designed for professional guitarists, recording studios, music stores and touring rigs, the N-audio 8X7 delivers professional amp switching with a relay-only signal path, advanced amplifier protection, a switchable power attenuator insert and MIDI control. Supporting tube, solid-state and bridged amplifiers, it lets you compare amplifiers instantly while keeping your equipment protected and your tone untouched.
Why Musicians Choose the 8X7
Stop reconnecting speaker cables every time you want to A/B compare amplifiers. The N-audio 8X7 was designed to make amp switching fast, safe and reliable. Whether you're recording in the studio, demonstrating equipment in a guitar shop or running multiple amplifiers on stage, every connection happens instantly with a single button or MIDI command.
The 8X7 continuously protects connected amplifiers using dedicated hardware safety loads, intelligent relay logic and cabinet detection, allowing safe and seamless switching between amplifiers and speaker cabinets.
Integrated FX-Loop Control
The optional FX-Loop Extension automatically routes the modulation and time-based effects connected to the send-return loop of the active amplifier.
Instead of reconnecting your delay, reverb, chorus or other effects every time you switch amps, the FX-Loop Extension automatically follows the selected amplifier. The extension is powered directly from the MIDI output of the 8X7, requiring no additional power supply.
Built for Modern and Vintage Guitar Rigs
The 8X7 supports guitar and bass amplifiers, including tube amplifiers, solid-state amplifiers, bridged (floating-ground) amplifiers and guitar combos. It is also compatible with virtually any active or passive power attenuator, including Two Notes Reload II, Fryette PS-2 / PS-100, Universal Audio OX, BOSS WAZA TAE and TAE Core.
Pure Tone Without Compromise
Every audio path inside the 8X7 uses high-quality relay switching. There are no active audio buffers, no audio processing and no tone coloration. A dedicated pop suppression circuit eliminates switching noises, allowing silent amp and cabinet switching without clicks or interruptions. Your guitar signal stays exactly as it should.
Designed to Protect Your Amplifiers
Tube amplifiers should never operate without a proper speaker load. For this reason, every amplifier connected to the 8X7 is continuously monitored and protected. Safety features include independent internal dummy loads, muted inactive amplifier inputs, a permanent safety load across the speaker bus, an intelligent switching sequence and cabinet detection.

8X7 Amp Cabinet Switcher – Frequently Asked Questions
Does the 8X7 affect the sound or tone of my amplifiers?
No. The audio path uses high-quality relays without active buffers, digital processing or tone-shaping circuitry. This keeps the signal transparent and prevents unwanted tone coloration.
Is the 8X7 safe for tube amplifiers?
Yes. The 8X7 is specifically designed for safe switching of tube amplifiers. Independent safety loads, cabinet detection, controlled relay sequencing and a permanent safety load across the speaker bus protect connected amplifiers during switching.
Which types of amplifiers can I connect?
The 8X7 supports tube, solid-state and bridged amplifiers, as well as guitar and bass amplifiers. Combo amplifiers can also be used when their amplifier output and internal speaker connections are accessible.
Can I use more than one amplifier at the same time?
No. The 8X7 is a mono amp switching system and allows only one amplifier to be active at a time. You cannot route one amplifier to one cabinet and another amplifier to a different cabinet simultaneously. The selected amplifier can, however, drive up to three cabinets connected in parallel.
Can I use a power attenuator or load box with the 8X7?
Yes. The switchable attenuator insert can route the selected amplifier through an external power attenuator or load box. Compatible devices include the Two Notes Reload II, Fryette PS-2 and PS-100, Universal Audio OX, BOSS WAZA Tube Amp Expander and TAE CORE, as well as virtually any active or passive power attenuator.
How many speaker cabinets can I use simultaneously?
You can connect up to seven speaker cabinets and select up to three of them simultaneously. Selected cabinets are connected in parallel, so their combined impedance is lower than the impedance of each individual cabinet. For example, two 16 Ω cabinets produce an 8 Ω load, while three 16 Ω cabinets produce approximately 5.3 Ω. Always confirm that the resulting total load is safe for the selected amplifier.
Can several amplifiers share the same Send-Return effects?
Yes. The optional FX-Loop Extension automatically connects your delay, reverb, chorus and other loop effects to the currently selected amplifier. It is powered directly from the 8X7 MIDI output and does not require an additional power supply.
How can the 8X7 be controlled?
The system can be controlled from its front panel, through MIDI or with the N-audio software for Windows and macOS. MIDI control also allows the switcher to be integrated into automated studio and live rigs.
Can the 8X7 be used for silent recording?
Yes. When a compatible load box or active power attenuator is connected through the attenuator insert, the selected amplifier can be used for silent recording without an active speaker cabinet.
Can the system be expanded beyond eight amplifiers?
Yes. Multiple 8X7 units can operate in a Master–Slave configuration. Two units can control up to 15 amplifiers, three units can control up to 22, and each additional 8X7 adds seven more amplifiers. All units share the seven speaker cabinets connected to the Master switcher. Detailed wiring and operation are explained in the complete 8X7 expansion guide.
Should I choose the 8X7 or the 4X4 Amp Cabinet Switcher?
Choose the 8X7 if you already have several amplifiers and plan to add more in the future. The 4X4 Amp Cabinet Switcher is better suited to smaller rigs with up to four amplifiers and four cabinets.
