8 –TWEETERTONE™
Many heads and cabinets include a so-called “L pad” HF control
on the back side of the cabinet. This control normally sets the
level of the tweeter in the cabinet and is generally used to adjust
the level of high frequencies.
TweeterTone is a far more intuitive and much better way of
adjusting the high frequency content. By using TweeterTone,
you do not simply turn the tweeter up and down in level – you
also get a much more musical and pleasant HF adjustment. And
instead of having to fumble around on the back of the cabinet,
you can simply use the TweeterTone knob right there on the
front panel.
Finally, TweeterTone is stored as part of your presets. This
allows you to adjust the level of HF with the rest of your sound
and thus go from a round and warm vintage sound to a sparkling
and crisp slap setting – simply by hitting a preset switch.
9 – TUBETONE
Most transistor designs have tried to replicate the tube sound
using a single small pre-amp tube. Generally, they fail as they
don’t take into account the crucial characteristics of the full
pre-amp and power amp sections – both of which are essential
to the sound.
Tubetone™ allows you to alter the “personality” and sound of
your BH500. The effects you can achieve range from a small
touch of classic tube amp response and character through
obvious, but pleasant “tube attitude” to highly overdriven.
Contrary to many tube simulations, Tubetone™ recreates both
the entire preamp section (located before the tone control
section) and the power amp section (located after the tone
controls). Not only does this give you the most realistic and
flexible recreation of the actual tube sound and response, the
BH500 tone controls also allows you to alter the behavior and
character of Tubetone™ the way you would on an actual tube
amp.
The TUBETONE knob adjusts the amount of both the preamp
and the power-amp tube simulation.
10 – MASTER (Volume)
Use the MASTER level knob to set the overall output level of the
amp. The master level also controls the level of the headphone
output. Note that master volume is not stored with presets.
11 – AUX IN (REHEARSE)
The AUX IN is a stereo auxiliary input. Any signal present on
the AUX IN phone jacks is played back through the PHONES
output. This allows you to play along with a rehearsal track
when checking out new stuff or when practicing to the beat of a
operatIon – front panel
