4.5 Amplifier Control Panel Functions
1. Bass Boost: Pressing in this button engages a filter that provides 3 dB of boost to the low and
high frequencies (below 100 Hz and above 12 kHz) to get a punchier sounds.
2. Limiter Indicator: This LED indicator will light whenever the limit circuit is active, meaning that
the signal level of the amplifier output is approaching clipping. The Limit Indicator may blink
occasionally, but if it blinks frequently or continuously, turn down the signal level at the signal
source, or turn down the GPS-8’s Level Control.
3. Signal Indicator: The LED indicator will light whenever there is a signal at the Mic/Line Input. It
senses the signal just after the Level Control, therefore if the Level Control is turned down, the
Signal Indicator will not light.
4. Mic/Line Selector: Leave this switch out when connecting a line-level signal to the Mic/Line
Input (from a mixer, a CD player or other line-level signal course). Push this switch in when
connecting a microphone to the Mic/Line Input. Since a microphone produces a much smaller
signal than a line-level signal, this provides an additional 40 dB of gain to boost the microphone
signal to a line level.
5. Level Control: This knob is used to adjust the signal level from Off to 45 dB of gain.
6. Mic/Line Input: Female XLR and 1/4" TRS combo connector accepting balanced or
unbalanced mic-level or line-level signals.
7. Parallel Output: Male XLR connector providing a direct signal from Mic/Line Input. Used to
form a daisy-chain with the input signal to another powered speaker.
8. Power Switch: Flip the switch up to turn the speaker on and flip the switch down to turn it off.
Make sure the Level Control is down before you turn it on/off.
9. Fuse Holder: If the unit will not power up, check the replaceable fuse. The unit includes a spare
fuse in the Fuse Holder.
10. AC Input: IEC socket for AC power. Always use a three-pin plug with a ground pin.
11. Mic On Indicator: This LED lights whenever the Mic/Line switch is pushed in.
12. Mains Switch: Allows the user to select different country voltage ratings.
