CONTROLS AND CONNECTIONS
1. Equalizer
- The EQ optimizes subwoofer performance
for audio or video playback.
2. 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.
3. 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.
4. Gain
- This knob controls the volume status of the
subwoofer.
5. Input
- The Input switches between the normal
line/speaker inputs and the direct-LFE input.
6. Highpass Output
- This toggle switch controls the
roll-off frequency of the high pass filter, the LOW
LEVEL OUT connectors, #7.
7. Low Level output
- These RCA output jacks are used
when it is desirable to limit the low frequencies to your
main receiver/power amplifier; see more on page 6
8. Low Level Input
- Main RCA input jacks, recommend
hook-up method. When using a single LFE (Low
Frequency Effects) cable from a Dolby Digital
receiver/processor, use either left or right RCA jack.
9. Fuse
- Use only same type of fuses. Use a 4A 250v
MDL Slo-Blo fuse for the 120v model, and a 2A
250v MDL Slo-Blo fuse for the 230v model.
10. AC Plug
- Plug in the AC line cord in here.
11. 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.)
12. LED
- This LED turns green when the HPS250 is
receiving power (is turned on) and is receiving a
signal.
13. Main
- This button is the master power switch.
