AC mains IEC cable socket (the power cable input). You can remove it by prying it open with a small screwdriver or hooked implement, after which the fuse tray can be removed.

SPEAKER OUTPUTS: CLEAN and CRUNCH – Use these outputs to connect an individual channel to a speaker cabinet. For example, you may have two (2) Airspeed 2 x 12 cabinets with different speaker sets, or you may have the Airspeed 4 x 12 diagonally switching speaker cabinet.

CRUNCH channel and CLEAN channel outputs on the head unit. That means that you can connect two or more 2 x 12 Airspeed cabinets, each with its own set of speakers, that you can alternate between, so that when you switch channels, you switch speaker sets/cabinets.

Sample Configuration #1 Your system comprises the Airspeed FM-50 Amplifier head and two (2) Airspeed 2 x 12 cabinets. This is the quintessential Airspeed setup using different speakers for different channels. IMPORTANT: Please check to make sure you have the correct impedance selected on the Airspeed amplifier head for the cabinets you are using.

In such scenarios, the volume is usually louder, as is gain breakup. In the case of the Airspeed amp, by rolling off the lows and mids, you avoid getting a tone that can wander and/or become too “loose” for the tone and music (a solo typically) that you’re playing.
2 switched outputs (CLEAN and CRUNCH) and 2 non-switched, parallel outputs • Non-switched output for using one 2 x 12 Airspeed speaker cabinet (or alternatively, can be used with one or more 4 x • 12 Airspeed speaker cabinets that have all the same speakers).
