Micro-VR Bass Guitar Amplifier
5
10. LIMIT LED: This LED illuminates when
the limiter circuit is activated, indicating
that the amplifier is nearing full output
and the limiter is keeping peak signals
from clipping the output.
If you notice that the LED is turning on
regularly, reduce the volume or the EQ
levels to prevent damage to your speak
-
ers.
11. AUDIO IN: The audio output from line-
level sources such as an iPod
®
, MP3,
or CD player, can connect to this 1/8"
TRS stereo input. The incoming audio is
mixed with the preamp signals, so you
can play along to a practice track, as
you listen with headphones. (The audio
coming in here only plays in the head
-
phones, and appears nowhere else.)
12. PHONES: Use this 1/8" TRS stereo
output to connect your headphones.
The output here is a mix of the line-level
signals reaching the amplifier, and any
incoming audio from the audio in jack
[11].
If you just want to listen and practice
through headphones, disconnect the
speaker-level outputs [17] from the
speaker cabinet. (This is a solid-state
amplifier, so there is no harm in playing
without speakers.)
Before putting on headphones, make
sure the volume control [8] is turned
down, and (if connected) any external
audio source has its level turned down.
This will reduce the chance of hearing
damage due to loud volumes.
13. POWER SWITCH: Use this illuminated
switch to turn the overall system power
on or off. Press the top of the switch to
turn on the power, and press the bottom
to turn it off.
