Powered Subwoofer TLX PS12
CONTROLS AND THEIR FUNCTION
1.
Output Level
- The Output Level adjustment
determines volume level strength.
2.
Crossover Frequency
- The Crossover Frequency
adjustment determines the highest frequency the
TLX PS10 will reproduce. It allows a seamless
transition from the subwoofer to the satellite
speakers.
3.
On (LED)
- This LED will light green when the unit is
plugged in and is receiving signal. When in
standby mode the LED is red.
4.
Low Level Input
- These left and right Line Level
Inputs are normally used when the receiver/
processor has line-level “pre-amp out” or subwoofer
out” jacks.
5.
Phase Switch
- The Phase switch is used to adjust
the relative polarity of the subwoofer. Normally
this switch is set to “0”.
6.
High Level Inputs
- These High Level Inputs are for
receivers that don’t have line-level “pre-amp out” or
“subwoofer out” jacks. When a pair of main or
satellite speakers are attached to the OUTPUT
terminals, frequencies below 180 Hz are attenuated
by the high-pass filter.
7.
Fuse
- Use only a slow-blo 2.0A 250V GMC fuse.
