AmP CHANNel
COmPRessOR
The COMPRESSOR (5) switch engages a simple but professional compressor circuit, optimized for bass guitar, which allows you to control the dynamics of your sound. This is especially helpful when using distorted
sounds. It can be switched on and off in real time.
AmP 1, AmP 2, AmP 3
The AMP CHANNEL runs your signal in parallel through three signal paths (two tube-driven and one solid state) that can be engaged in whichever combination you want. The AMP 1 (8) signal passes through two
ECC83S tubes for heavy tube distortion. The AMP 2 (10) signal passes through one ECC83S tube for a softer tube distortion. The AMP 3 (12) signal passes through a FET to create solid state distortion. Simply turn on
the channel(s) you want by pulling the knob(s) out, and adjust the level(s) to taste. Turn any distortion channel off by pressing in its knob.
eQUAlIZATION
The STUDIO PRE AMP CHANNEL features two bands of EQ:
The LOW EQ control (14) is set to a center frequency of 100 Hz. This means that it either boosts or cuts the volume of the frequencies around 100 Hz, to a maximum of 16 decibels.
The HIGH EQ (16) control boosts or cuts the frequencies around 4 kHz, by as much as 16 decibels.
VPf fIlTeR
The VPF (18) (Variable Pre-shape Filter) boosts lows (around 35 Hz) and highs (around 10 kHz), and cuts mids at 380 Hz. This filter sounds great for rock music and is also a favorite of many slap players. At higher
volumes, turning the VPF up high will result in more output limiting due to the increase in low frequencies.
HIgH PAss fIlTeR
The HIGH PASS FILTER (19) cuts low frequencies from your signal, passing only high frequencies. This creates a clearer signal when using distortion, because distorting bass frequencies can create a very muddy sound!
As you turn this knob up, a wider and wider range of low frequencies gets cut.
AmP OUT leVel
The AMP OUT LEVEL (21) control adjusts the level of signal that comes from the balanced AMP XLR OUT (26).
mIX / mAsTeR
mIX CleAN/AmP
The MIX CLEAN/AMP control determines the balance between the CLEAN CHANNEL and AMP CHANNEL signals that are sent to the MIX OUT outputs (35, 36) and to the SPEAKER OUT (26).
mAsTeR leVel
The MASTER (23) controls the level of signal sent out of the SPEAKER OUT (26).
