Battery Operation - Remarks
18650 Li-Ion batteries are becoming increasingly more popular on the market. The option
of quickly removing the battery also allows the user to quickly replace it, thus allowing him/her
to use the headphone amp in a manner that is continuous and seamless. Having a spare 18650
battery at hand, along with an external charger, may make it much easier to use the headphone
amp, should you have limited or no access to the mains.
If we are not going to use the headphone amp for a longer period (a month or longer), it is
recommended to charge the battery and then remove it from the instrument. The battery
should be stored in a dry and safe place, away from heat sources, with the battery terminals
being protected from accidental short-circuit.
Note:
The headphone amp may only be powered by the 3.7V 18650 Li-Ion battery. Using any other cell
may damage the headphone amp, or even lead to an explosion of the battery which may
consequently cause fire and/or injury.
Other Applications of the Headphone Amp
When you are not using the headphones, apart from using the standard 1/4" TS jack
instrument output, the headphone output may be used to transmit the signal to an additional
receiver - a sound recorder, effects, monitors, or extra stereo amp. Make sure that the coupled
device can safely receive the headphone output signal. Should a need emerge, the output level
can be adjusted with the bass's volume knob.
