1. POWER switch - The power switch has three positions:
OFF - AUTO - ON. While the OFF and ON positions are self-
explanatory, the AUTO position instructs the SUB-1500 to
remain in STANDBY mode until the unit receives an input
signal.
3. LEVEL control - This control adjusts the subwoofers
MASTER output level. Turn clockwise to INCREASE and
counter-clockwise to DECREASE level.
4. CROSSOVER control - The CROSSOVER control adjusts
the SUB-1500's low-pass frequency filtering for subwoofer
output. The available LOW-PASS range is: 40 Hz - 120 Hz.
7. HI-LEVEL IN jacks - These MDP binding posts are for
direct connection of speaker output from an external
amplifier.
9. VOLTAGE selector - The VOLTAGE SELECTOR selects the
amplifier to run on either 110V or 240V.

2. PHASE switch - This switch toggles the PHASE of the
subwoofer with respect to the main speakers. If the
subwoofer is out of phase with the main speakers, bass
response is at a reduced performance level and may sound
"weak". When all speakers are in phase, full-frequency
response is at an optimal level.
NOTE: If the SUB-1500 unit does not receive an
input signal for approximately 10 minutes, it will
switch to stand by mode until it receives a further
8. HI-LEVEL OUT jacks - These MDP binding posts are for
direct connection to main system speakers or external devices.
NOTE: These inputs are typically used for connecting
to a system that does not have "pre-out" or line level
outputs available.
6. LINE IN jacks - These jacks provide a LINE-LEVEL
connection from external devices with LINE OUT, PRE-AMP,
LFE or LOOP RCA outputs.
5. LINE OUT jacks - These jacks provide a LINE-LEVEL
connection to external mixers/amplifiers with LINE IN or
LOOP RCA inputs.
NOTE: These inputs are typically used for signal
output to main speakers or for daisy chaining.
NOTES: PLEASE ENSURE THIS CONTROL IS SET
CORRECTLY BEFORE PLUGGING IN AND POWERING
ON THE SUB-1500. IF THIS CONTROL IS NOT SET
CORRECTLY PRIOR TO USING THE SUB-1500, YOU
MAY DAMAGE THE UNIT AND VOID YOUR
WARRANTY. SELECT 110V for North American based
power and 240V for European based power.
10. AC MAINS terminal - For connecting the SUB-1500 to
