Powered Subwoofer HPS-250
CONTROLS AND THEIR FUNCTION
1. Gain - This knob controls the volume status of the
subwoofer.
2. Phase - The phase switch is used to adjust the
relative polarity of the subwoofer. When the phase
switch is up, the phase is normal - when the switch
is depressed, the subwoofer is 180 degrees out of
phase.
3. Crossover Frequency - The crossover frequency
knob determines the highest frequency your
subwoofer will reproduce. It allows a seamless
transition from the subwoofer to the satellite
speakers.
4. LED - This LED turns green when the HPS250 is
receiving power (is turned on) and is receiving a
signal.
5. Main - This button is the master power switch.
6. 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. If a single cable mono
or subwoofer source is connected to the HPS250, a
Y-cable must be connected to the subwoofer for
full output.
7. Fuse - Use only same type of fuses. Use a 2A 250v
MDL Slo-Blo fuse for the 120v model, and a 1A
250v MDL Slo-Blo fuse for the 230v model.
8. AC Plug - Plug in the ACline cord in here.
9. High Level Inputs - These High Level Inputs are for
receivers that do not have line-level “pre-amp out”
or “subwoofer out” jacks. When a pair of main or
satellite speakers are attached to the OUTPUT
terminals, they are driven the full range of
frequencies as generated by the music source
(receiver, amplifier, etc.)
