4. FUNCTIONS OVERVIEW
• LEFT CHANNEL
GAIN LEFT (1) - Controls the level of input into the pedal, from -60÷ +23 dB. If playing through the preamp causes the blue “CLIP” (2) light to turn on at all, you should turn down the
GAIN (1) control to avoid distortion. When you first plug into the amp, start with the GAIN (1) and MASTER (10) controls set at their lowest levels, in other words turned all the way counter-
clockwise. Then, turn your instrument’s volume up to its full level and play as hard as you do in your most aggressive moments, and turn up the GAIN (1) control until the blue light starts
illuminating. Next, back off on the GAIN (1) just enough so that the light stays off as you play. This method will result in the optimal gain setting for the bass you’re playing. Once you’ve set
the GAIN (1) level, use your MASTER (10) knob to control the volume of your bass.
Markbass amps are designed to faithfully reproduce the natural sound of your bass. If you have a good instrument, very little equalization (EQ)—if any—should be required.
The LOW (3) EQ control is a shelf equalization control at 60 Hz. This means that it either boosts or cuts the volume of the frequencies around 60 Hz, to a maximum of 16 decibels.
LOW frequencies constitute music’s sonic foundation they give power to your sound, physically resonating your listeners’ bodies… and yours!
The M LOW (MID LOW) (4) EQ control boosts or cuts the frequencies around 360 Hz, by as much as 16 decibels. M LOW makes your bass sound loud, projecting the sound over long
distances, filling the room.
The M HIGH (MID HIGH) (5) EQ control boosts or cuts the frequencies around 800 Hz, by as much as 16 decibels.
M HIGH conveys the pitch of the notes that you play. Clarity of this
range ensures that the melodies in your bass lines are heard. If detail is missing in this
range, your melodic contribution to the music will suffer.
The HIGH (6) EQ control boosts or cuts the frequencies around 5 kHz, by as much
as 16 decibels.
HIGH frequencies carry the percussive content of your playing, the attack of your
notes, the sound of your finger or pick passing over the string, fret noise, and in the
case of slap bass, the ‘tick’ noise produced when the strings bounce off the frets.
Since the GROUND STEREO PRE has been designed to give you clear, detailed and
musical sound at all frequencies, when the EQ section is set ‘flat’ with all EQ knobs
at 12 o’clock you should hear a very true mirror of the sound of your bass. However,
if and when equalization is required, you will find this preamp’s EQ controls to be
powerful.
• RIGHT CHANNEL (same as LEFT CHANNEL)
The MASTER (10) volume regulates how much output comes out of the preamp into
your power amp/ powered speaker/s, mixer, etc.
MUTE LEFT (11) / MUTE RIGHT (12) -
Toggles between “on” and mute mode. The
mute LEDs (7-8) illuminate when the channel/s is/are muted.
FX BYPASS (10) –
This switch allows you to bypass the FX loop.
