Save Your Packing Materials
The box and packing materials were specially designed to protect the amplifi er
during shipping. Save all this stuff in case you need to re-ship the Loudbox Mini.
Hear This!
The Loudbox Mini 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.

To ensure against permanent hearing loss, wear hearing protection when you perform with
amplification.
NOTE: Operate the amplifi er only at the voltage as indicated
on the rear panel. Do not defeat the ground prong on the
AC cable; the safe operation of this amplifi er depends on a
proper ground connection.

Getting Started
Here are some basic setup tips to help get you going. To operate your Loudbox
Mini safely, please read the entire manual, especially the Important Safety
Instructions on page 2.
If your amplifi er has an operating voltage of 120V, plug the provided AC line
cord into the back of the amplifi er.
If your amplifi er operates at 230V, you must supply your own detachable power
cord. The cord you supply must have an IEC-style 320 connector at one end and
a male AC plug appropriate for your area at the other.
1. Locate the Power switch (next to the rear panel power cord terminal) and
switch it off, then connect the power cord.
2. Plug the Loudbox Mini into an electrical outlet with the appropriate AC voltage.
3. Turn down the Master Volume control and turn on the Power switch.
4. Connect your instrument to the Instrument input with a shielded ¼” cable.
5. Raise 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 it’s maximum with many passive
soundhole pickups.
6. Slowly raise the Master Volume to the desired level.

Front Panel
1. Instrument Input
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 fl atten it out (or cut) 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 mic into this XLR input for vocal or for your instrument. The
Loudbox Mini 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 microphone’s sound. In general, boost bass at
low volumes and fl atten it out (or cut) 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 with the Master Volume. In general
put the Master Volume as high as possible (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 above the AC power cord terminal.

Rear Panel
1. AC power
Operate the amplifi er only at the voltage indicated on the rear panel.
For 120V amplifi ers purchased in the USA, Canada and Mexico, plug in the
supplied detachable AC power cable.
For 100V and 230V amplifi ers purchased outside the USA and Canada, you will
need to supply your own detachable AC cable. This cable must have an IEC-
style 320 connector at one end, and a male AC plug appropriate for your region
at the other.
Disconnect device is AC inlet or power switch.
2. Power switch
Lower the Master Volume before you turn on the amp. Flip the power switch to
the up position.
3 & 4. Aux Input - 1/4” & 1/8”
Plug in a line level stereo audio source such as a CD or MP3 player in this input.
Both inputs may be used at the same time. They are stereo (TRS) inputs, however
the left and right signals are mixed to mono.
5. Mix D.I. (Post)
Plug in here when you wish to send signals from both Channel 1 and 2 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 fl at (straight-up, twelve o’clock). In this
position, there is no 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’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.
