Hear This!
The Loudbox Mini Charge amplifier is capable of cleanly reproducing the sound
of your instrument at very high volume levels. Prolonged repeated exposure
to high sound pressure levels (SPLs) without protection can cause permanent
hearing loss. OSHA has set guidelines and specified permissible sound-exposure
limits for those who work in high SPL environments.

Getting Started
Your new Loudbox Mini Charge is a portable, battery-powered amplifi er de-
signed to faithfully reproduce the sound of acoustic instruments and a diverse
assortment of vocal or recorded accompaniments.
With the addition of Bluetooth
neatly add backing tracks or other accompaniment to your performances, jams,
or wherever your Loudbox Mini Charge takes you and your music. Where Are
You Going to Take It? ™
Here are some basic setup tips to help get you going. To operate your Loud-
box Mini Charge safely, please read the entire manual, especially the Important
Safety Instructions on page 2.
1. Locate the Power switch (next to the rear panel power cord socket) and switch
it off, then connect the provided AC adapter into the back of the amplifi er and
the provided line cord into the AC adapter.
2. Plug the Loudbox Mini Charge line cord into an electrical outlet with the ap-
propriate AC voltage, 100-240VAC 50/60 Hz.
3. Turn down the Master Volume control and turn on the Power switch. The
Power Indicator should illuminate. Either the Battery Indicator will illuminate
if the battery is fully charged or the Low Battery Indicator will illuminate if the
battery needs charging.
4. Connect your instrument to the Instrument input with a shielded ¼” cable.
5. Gradually increase the Instrument channel Gain:
• For instruments featuring active (battery-powered) onboard preamps,
start with the control around 10 o’clock.
• For passive pickups, you may start with the control set much higher.
It is normal to run this control near its maximum with many passive
soundhole pickups.
6. Slowly raise the Master Volume to the desired level.

This 1/4” input accepts all types of passive or active acoustic pickups.
2. Phase
Use the Phase switch to improve bass at low volume and suppress feedback at
high volumes.
3. Gain
Use the Gain knob to set the signal level for the instrument input.
4. Low
Boost here to add weight to the sound. In general, boost bass at low volumes
and cut bass at higher levels. With the dial set at 12 o’clock, the control is effectively out of the circuit.
5. Mid
This control affects how well the instrument blends in or stands out in the mix. At
loud volumes, a midrange cut will achieve a more natural sound. With the dial
set at 12 o’clock, the control is effectively out of the circuit.
6. High
Boost highs to add “air” to the sound of the instrument. With the knob set at
12 o’clock, the control is effectively out of the circuit.
7. Reverb
Controls the amount of digital reverb in the Instrument channel.
8. Chorus
Controls the depth of two separate chorus presets.

9. Mic Input
Plug in a balanced microphone into this XLR input for vocal or for your instrument. The Loudbox Mini Charge makes an excellent mini PA or vocal monitor.
You may also connect an outboard preamp with balanced XLR out to this input.
10. Gain
Use the Gain knob to set the signal level for the Microphone input.
11. Low
Boost here to add weight to the sound. In general, boost bass at low volumes
and cut bass at higher levels. With the dial set at 12 o’clock, the control is effectively out of the circuit.
12. High
Boost highs to add “air” to the sound of the microphone. With the knob set at
12 o’clock, the control is effectively out of the circuit.
13. Reverb
Controls the amount of digital reverb in the Microphone channel.
14. Master Volume
Set the overall level of the Loudbox Mini Charge with the Master Volume. In
general, put the Master Volume as high as possible using less Gain (2 o’clock to
5 o’clock) to achieve the cleanest sound.
15. Power
Lights up when the amplifi er power is on. The Power switch is located behind
the amp next to the power cord socket.

18. Green Battery Indicator
When on, this green indicator tells you that the battery is charged, functional
and power is available.
19. Red Low Battery Indicator
When on, this red indicator denotes that the battery’s available charge is low. All
indicators will turn off and the amplifi er will shut down if the battery no longer
has enough charge to power the amplifi er. At this point, the amplifi er cannot be
powered up until the AC adapter has been plugged in to recharge the battery.
The amplifi er can be used normally while charging.
20. Yellow Charging Indicator
When on, this yellow indicator denotes that the battery is charging. It only illuminates when the AC adapter is plugged in and the battery is receiving external
power to recharge. After the battery is fully charged, this indicator will turn off.
The Charging Indicator will also be off if the AC adapter is not connected or
receiving power.

Rear Panel
1. DC In
Operate the amplifi er only at the voltage indicated on the rear panel.
Plug in the supplied DC cable into the DC In power socket on the amp. Plug the
provided AC cable with the female IEC-style 320 connector into the AC Adapter
and the male AC plug appropriate for your region into an outlet.
The DC In is the power input, and when connected appropriately as described
above, it will also simultaneously charge the battery if it is below full charge. The
amplifi er may be used while charging and may be charged when powered down.
See the battery indicators on the front panel for battery charge status.
2. Power switch
Lower the Master Volume before you turn on the amp. Flip the power switch to
the up position for On.
3. Aux Input - 1/8”
Plug in a line-level stereo audio source such as a CD or MP3 player in this input.
The input is stereo; however, the left and right signals are mixed to mono within
the amplifi er.
4. Mix D.I. (Post)
Plug in here when you wish to send signals from both Channel 1 and 2, plus 1/8”
Aux and Bluetooth signals, to a mixing console or a slave amplifi er. This post-EQ
output is always ground-isolated to prevent ground loop hum.

Tone Tips
Set up
For reference, start with the tone controls set straight-up, (twelve o’clock). In this
position, there is no additional boost or cut equalization applied to your sound.
Begin at a very low volume and work your way up. As you turn up, try adjusting
the Loudbox Mini Charge’s tone controls as recommended below.
1. Low volume
At a low volume (just above conversation level) our ears are not very sensitive
to bass and treble, so give the Low and High controls a good boost. Try three
o’clock on the dial.

2. Medium volume
At medium levels, when you need to raise your voice to be heard over the music,
the human ear is quite sensitive to midrange. Cut the Mid control to about ten
o’clock or to your taste. At this level, our perception of bass and treble starts to
catch up to the rest of the tonal spectrum, so you can back off the Low and High
controls slightly for good tonal balance.

3. High volume
At loud levels, when you must shout to be heard over the music, your ears (and
your audience) will benefi t from a deep midrange cut. Set the Mid dial between
nine and seven o’clock. Our perception of bass and treble “fl attens out” at high
volumes, so you won’t need much, if any, Low or High boost. Set the Low and
High knobs to between twelve and one o’clock. In many cases, you can also
improve the tone at very high volume if you cut bass. Try setting the Low knob
between ten and eleven o’clock.
