A) Mono Balanced Input
- 61K Ohms balanced input connector - 200mv in produces 90dB of output
(Reference/THX input sensitivity mode).
Pin Polarity:
1. Ground
2. Plus
3. Minus
B) Variable Low-Pass Filter
- 50Hz to 125Hz, 36dB per octave low-pass filter. This optional adjustment is
activated by setting the 3-way toggle switch located to the right of this knob to the center position.
C) 3-way Low-Pass Filter Toggle Switch
- In the THX position of the switch the low-pass filter of the
subwoofer is bypassed. This mode should be used when operating the MPS-5310 with an external bass-
management box or consumer Dolby Digital/THX receiver/decoder. In the center position, this switch
activates the variable low-pass filter (B). The bottom position of this switch activates an 80Hz, 24dB per
octave filter. This mode should not be used when the subwoofer is being connected to an external bass
management box.
D) Phase Switch
- Allows the subs phase to be changed between 0 degrees and 180 degree out of
phase so as to best accommodate subwoofer location and crossover performance with regards to the
main speakers.
E) Standard IEC Power Cord Receptacle

G) Bass EQ Switch
-
THX Position
-3dB at 35Hz (anechoic)
+/-1dB pass band (40Hz to 150Hz)
-3dB at 200Hz
Rooms that are below 6,000 Cubic feet in volume typically have a rising characteristic below 35Hz. When
the subwoofer is used in rooms of this size or smaller, the subwoofer should be set in the THX position for
flat in-room response.
Anechoic Position
-3dB at 20Hz (anechoic)
+/-1dB pass band (40Hz to 150Hz)
-3dB at 200Hz
In this position the subwoofer has the greatest low frequency extension and in small rooms often provides
a rising characteristic below 35Hz.
H) Input Gain Switch
- In THX mode, the gain is fixed and provides 90dB of output when a 200mv
signal is applied to the balanced input (100mv unbalanced).
I)
Variable Gain Knob
- Variable gain knob provides gain settings from -
∞
to approxi20dB
above reference. Reference is equal to the input gain switch being set to the THX position.
J)
Left Un-balanced Input
- 15K Ohms balanced input connector - 100mv in produces 90dB of output
(Reference/THX input sensitivity mode)
K) Right Un-balanced Input
- 15K Ohms balanced input connector - 100mv in produces 90dB of output
(Reference/THX input sensitivity mode)
