Hughes & Kettner Red Box Pro (speaker tap and cabinet emulator)

Hughes & Kettner Red Box Pro. $129. Cab-sim, floor unit. 2x12 or 4x12 cab. Accepts speaker load [?].

From a previous H & K page: "Eliminates amp-miking hassles, providing rich, full cabinet sound. Simply connect the RED BOX to the line out jack of your amp or preamp, or patch it between your amp head and speaker. Its complex filtering system delivers a balanced signal that simulates the sound of a miked cabinet with amazing accuracy. Fast, simple setup and consistent sound quality - the only way to "mike" up your rig. Cabinet simulator with two selectable characteristics (combo/4x12"). Can be powered by phantom power, external adapter, or battery. Ground Lift switch. Inputs and outputs: Line in, speaker in, speaker through, electronically balanced low-impedance out (XLR)."

official Red Box Pro page - excerpts:

The world's most popular cabinet simulator. Improved professional version, the Red Box Pro. Refined for even greater realism. Balanced transformer and ground lift switch, for both impedance matching and galvanic isolation, and a ground lift switch for knocking out hum. This allows you to connect your guitar amp to your mixing console over lengthy cables without worrying about extraneous noises or ground loops.

No batteries or external power supplies required.

New: Power Amp Simulation. Not just the sound of the speaker cabinet, but the sonic subtleties introduced by the guitar amp's power amp section are now accurately recreated as well.

The Red Box Pro can now double as a standard D.I. box at the flick of a switch. You can bypass the entire Red Box Pro filtering section and connect an acoustic guitar, a bass, or a keyboard.

Controls: 4x12"/Combo switch

Speaker simulation: 4x12" + 2x12" combo

Connections: Line in, Speaker in, Speaker through, mic. level balanced out (XLR).

Approx. Weight: 200 g.

Dimensions: 12 x 4 x 7.2 cm.

Special features: 2 characteristics, Ground Lift switch, Power supply by battery, AC-adaptor or phantom.

List $129.

You can use the Red Box as part of the sound along with the mics. A speaker level output from the amp is plugged into the Red Box and the Red Box puts out two signals - an output to the speaker and a mic level feed to the console. There's definitely a phase issue between the Red Box and the mics because the sounds arrive at two different speeds (the speaker-to-microphone path takes longer). Sometimes you'll get interesting cancellations. You can use the mics on one side of the mix and the Red box on the other to give it a stereo feel.

Delivers an authentic guitar cabinet tone when the cabinet simulator is switched on. Simulates the bark that you get from playing muted power chords through a screaming amps and cabinet. We also ran the bass through the Red Box Pro, and the Guitar Cabinet Simulator gave it a nice rounded tone. The Red Box Pro fixed ground loop problems.


I think it might be possible to get a pretty authentic tone at the output transformer *if* you have saturated power tubes directly interacting with an actual hard-driven guitar speaker, with no attenuator getting in the way. Direct-inject to the mixing board might work much better when the power tubes are feeling an actual hard-driven guitar speaker and responding accordingly. If my suspicion is correct that a guitar speaker significantly feeds back (in a complex, dynamic way) to the power tubes, then, my hypothesis would imply that the Red Box should work well *unless* the amp is pushing just a dummy load, such as the Marshall Power Brake.

Connection options for the Red Box



The THD Hot Plate or Marshall Power Brake are overkill if you are
just trying to tap the speaker terminals. The H&K Red Box might
serve better, it's only about $100.

Some of these devices force you to use the built-in speaker simulator (essentially a low-pass
filter).

The Red Box is the standard piece of gear to tap
the signal at the speaker terminals. It still requires driving a guitar speaker loud.
