Connections:

Tube amp

VERY IMPORTANT: Turn off power to the amp before making

any

connections to

the RED BOX. Failure to do so can result in non-warranty damage to the RED BOX. Also VERY IMPORTANT: If

you connect a tube amp to the SPEAKER IN jack, you

must also connect a speaker (or at least a dummy load) to the RED BOX SPEAKER THRU jack. Failure to do so may damage the amp. (Just like revving an engine in neutral without a load at maximum RPM’s can damage an engine).

First, install a 9-volt battery Power from this battery is automatically turned on by the insertion of a standard

1/4"

plug into either the LINE IN or SPEAKER IN,

and is turned back off simply by removing the plug.

A tube output stage plays a major role in the creation of an amplifier’s tone.

With tube amps it is therefore recommended that the RED BOX be connected

to the amplifier’s loudspeaker output (and the RED BOX SPEAKER THRU be

connected to the speaker). With transistor amplifiers, however, for the sake of

the best dynamics and signal-to-noise ratio, the preamp signal (LINE OUT) is

preferred.
