Welcome
Thank you for making Fishman a part of your acoustic experience. We are proud to offer the finest acoustic amplification products available; high-quality, professional-grade tools which empower you to sound your very best.

Getting Started

Your new Loudbox Mini Charge is a portable, battery-powered amplifier de- signed to faithfully reproduce the sound of acoustic instruments and a diverse assortment of vocal or recorded accompaniments.
With the addition of Bluetooth® wireless connectivity, you can now easily and neatly add backing tracks or other accompaniment to your performances, jams, or wherever your Loudbox Mini Charge takes you and your music.

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 amplifier and the provided line cord into the AC adapter.

2. Plug the Loudbox Mini Charge line cord into an electrical outlet with the appropriate 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:

6. For instruments featuring active (battery-powered) onboard preamps, start with the control around 10 o’clock.

7. 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.

8. 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 cut bass at higher levels. With the dial set at 12 o’clock, the control is effec-tively 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 amplifier power is on. The Power switch is located behind the amp next to the power cord socket.

16. Bluetooth® Indicator
    This green indicator will display a medium flash indicating the Bluetooth® module is ready for pairing. It will display a slow flash indicating the module is ready for reconnection with a previously paired device. The indicator will be on when play-back is active and display a fast flash when playback is paused.

17. Bluetooth® Pairing
    To pair a Bluetooth® enabled device for the first time, hold the Pairing button more than 5 seconds. You will hear an ascending tone and the Bluetooth® Indicator will change from a slow flash to a fast flash indicating it is ready to pair. Ensure your Bluetooth® enabled device is in pairing mode. Once paired the indicator will stop flashing and will allow you to stream music to the amplifier.
    If the button is pressed during paired playback, the playback will be paused and the Bluetooth® Indicator will display a fast flash. Press the button again to resume playback and the Bluetooth® Indicator will return to on.
    To activate Bluetooth® for a previously paired device, hold the Pairing button for approximately 1-2 seconds (must be less than 5 seconds). An ascending tone will play briefly to indicate the Bluetooth® is powering on. The Bluetooth® Indicator will slowly flash informing it is ready to reconnect and will pair if your device is in pairing mode.
    To turn off the Bluetooth® when already paired, hold the button for 1-2 seconds. A descending tone will indicate that the connection is powering down and the Bluetooth® Indicator will turn off.

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 amplifier will shut down if the battery no longer has enough charge to power the amplifier. At this point, the ampli-fier cannot be powered up until the AC adapter has been plugged in to recharge the battery. The amplifier 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.
    Be sure to check out our Good habits to prolong battery life on page 14.

Rear Panel

1. DC In
   Operate the amplifier 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 amplifier 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 amplifier.

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 amplifier. 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 sensi- tive 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. ![FISHMAN-428186-Loudbox-Mini-Charge-Amplifier-09Featured Image:

3. High volume
   At loud levels, when you must shout to be heard over the music, your ears (and your audience) will benefit from a deep midrange cut. Set the Mid dial between nine and seven o’clock. Our perception of bass and treble “flattens 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.

Good habits to prolong battery life

Loudbox Mini Charge houses a sealed lead acid battery, so you can take
it nearly anywhere. Similar to a common car battery, proper maintenance will lead to a long life span of up to 5 years, possibly longer. Here are some helpful tips to prolonging battery life.

Always charge it to full before playing for an extended period of time. While charging, your Loudbox Mini Charge will continue to perform without any impact to output level or sound quality.
When the Low Battery light comes on, plug it in and recharge it to full. Like a car battery, if you let it sit for months after the Low Battery light has lit, the battery will begin to lose its ability to reach full capacity and impact its performance.

If left for long periods of time, especially if the Low Battery light was on before sitting, it may take as long as 24 to 48 hours to charge back up to capacity. The longer it sits uncharged, the longer it will take to return to full charge. Due to the chemistry of lead acid batteries, an older battery left this way may not ever return to full charge and you may see performance times shorten.

If you feel you need a battery replacement, do not attempt to replace the battery yourself without first contacting Fishman Support at https://www.fishman.com/support/. We offer a replacement kit containing an approved battery with instructions on how to replace it yourself.

Only use the supplied power adapter to power and charge the Loudbox Mini Charge. Do not attempt to connect a battery directly to the power inlet
Do not attempt to replace the internal battery with one of larger capacity. The charge circuit is matched to the battery specified for this amp and any modifications will void your warranty.
