Thunderfunk bass amps are capable of producing sound levels that can cause permanent hearing
loss. This is especially true in when additional sound sources, such as when headphones are used.
Also, please respect the ears of the audience that has come out for you.
Phones/Line Output
This built-in front panel jack can be used for either headphones, or as a line-out connection. You
canuseastandard¼phoneplugineitherstereoormonoconguration,howevertheoutputwill
be mono, and is driven by the power amp.
If you want to practice silently through headphones, speakers do not need to be connected in the
back. If you use it as a line-out connection, remember this output is after the entire preamp and
powerampcircuitry,soallcontrolsandsettingarereectedatthisjack.
Power
This switch turns the system on or off. There is a Green LED to indicate power is applied, and the
fuse is good. If the indicator light does not come on, either the AC power cord is disconnected, the
walloutletisn‘tworking,thefuseisblown,orforsomeotherreasonthereisnopowertotheunit.
The power to the amp is slow-start, meaning that the unit will not come on instantly, saving your
ears and speakers from the “POP” often associated with high power equipment.When turned on,
there is a couple of seconds delay before the mute circuit allows the preamp signal to get to the
power amp. Similarly, the amp shuts down without the “POP” caused by DC bias shifts in other
amps not similarly equipped.
It is still considered good practice to set the master volume control at minimum when powering
the amp up and down, and when plugging or unplugging your instruments. This will prevent any
unexpected signal from being sent to your speakers.
