1. Input and –10 dB pad button – Plug in and
start with the pad in the up/passive mode. If your bass’s
output distorts the input section, switch to the
down/active mode. A “passive” instrument has no
built-in preamp and does not use a battery. An “active”
bass utilizes a battery operated preamp.
2. Amp Models – Select one of these buttons to
select one of 4 groovealicious Amp Models or hit R&B
and Rock together to get Synth Bass and all the
LowDown controls will automatically dial in to sound
great, so you can just play! These buttons come pre-
loaded with great factory presets but can be used to
save your own custom settings.
3. Drive - is like the volume or gain knob on other
amps; controls how much “dirt” you get in your sound.
4. Tone Controls – Bass, Low Mid, Hi Mid and
Treble controls are customized for each Amp Model
to give you optimal tonal control.
5. Opto Comp - Turn clockwise to even out your
playing dynamics (more compression). Watch for the
Threshold light, and set the knob so that it comes on
just at the point where you play with your typical
intensity.
6. Master Volume - You can choose the overall
volume of the amplifier, without affecting your tone.
7. CD/MP3 – Plug in any audio source and it feeds
directly into the LowDown’s speaker or headphones
so you can jam with your favorite music or a drum
machine. Use the input device’s output control to
adjust its volume.
8. Headphone - Listen with headphones to your
LowDown mixed with what ever you would like to
input into the CD/MP3 jack.
9. XLR Direct Out – This gives the sound man
a simulation of a miked cabinet that is model specific.
To the left of the input is a ground lift.
10. Preamp Out – Plug in here to send your sound
to an external bass amp, power amplifier, mixing
console, or house PA system.
11. Power – on or off. The amp sounds better on.
