Hughes & Kettner RED BOX 5 Manual Download Page 1

The Hughes & Kettner RED BOX 5 converts line and speaker signals sourced 
from guitar amps into balanced, frequency-compensated, microphone-level 
signals with tonal characteristics of a 4 x 12" cabinet. It lets you feed a 
guitar amp’s speaker out, line out or FX send straight into a mixing console’s 
microphone input. 

Note:

 The RED BOX 5 emulates the speaker, not the microphone. In other words, 

signals provided by the RED BOX 5 sound like those of an actual cab rather than 
that of a microphone picking up the sound of a cab. The benefits are considerable: 
You get a fatter, punchier and more direct signal with far greater presence, 
bandwidth and dynamic range than signals captured with a microphone. With the 
RED BOX 5, you can take the PA and playback device out of the sonic equation 
and deliver the sound of a guitar cabinet straight to audiences and listeners. Best 
of all, there’s no latency, spillover or crosstalk from other signal sources such as 
drums, frequency cancellations caused by neighboring microphones or any danger 
of feedback. 

This signal is the best you can get for processing with compressors, equalizers, 
reverb effects and microphone simulations on stage and in the studio.

Tip: Experimentation is very much encouraged: Make the most of both worlds 
by mixing the signals from the RED BOX 5 and a microphone. The RED BOX 5 
lends every microphone signal more girth and presence without detracting from its 
inherent characteristics.

Connections

The RED BOX 5 provides one unbalanced ¼" (6.3 mm) jack input (IN) for line and 
speaker signals and two different outputs: One unbalanced ¼" (6.3 mm) jack (THRU) 
lets you patch through the unprocessed signal. One balanced XLR connected lets 
you feed the processed signal to a mixing console. Note that some mixing consoles 
do not provide phantom power. In that case, the RED BOX 5 is ready for an optional 
power supply (see Technical Specifications) and comes with a compartment 
accommodating a 9 V battery (unscrew the feet to open the housing).
