Morel SOUNDSPOT ST-95 - Manual (Page 16)

2. RCA jacks
The input terminals connect to the subwoofer (line level)
outputs of an amplifier. The output terminals provide an input
bypass for connection to a second subwoofer, or any other
purpose.
3. PHASE control
The phase control allows phase adjusting of the subwoofer to
match that of the other speakers in your home theater system.
With the system turned on, turn the phase control first to one
extreme then to the other, and leave it in the position at which
the bass level in your room sounds strongest and deepest.
4. CROSSOVER control
The crossover control determines the range of frequencies your
subwoofer will reproduce. When turned to 40Hz, the subwoofer
will only issue the lowest bass frequencies. As you turn the
knob towards 160Hz, the subwoofer will reproduce a wider
frequency range. When the crossover control is adjusted
correctly, the subwoofer, together with the other speakers in
your system, reproduces the entire range of bass.
5. LEVEL control
The level control adjusts the sound level of your subwoofer. Set
to provide the required level of bass relative to the sound
reproduced by the other speakers in the system. The sound
level reproduced by the subwoofer will change as you modify
the volume control setting on your amplifier, maintaining the
relative level set by this control.
6. BINDING POST terminals
These are input terminals for connection to the high-level
outputs of an amplifier (parallel to the front speaker connection).
Output terminals provide a filtered output to surround speakers.
See the Connection Guidelines for details.
