Step 1:

LINE IN: the RCA line-level female input, second row, accepts a standard RCA male plug. Connect a shielded coaxial cable, with male RCA plugs on each end, from the A/V receiver or A/V preamp processor’s Subwoofer Output jack to the RCA LINE IN female jack on the EP125 or EP175.

BALANCED XLR LINE IN: if the A/V receiver or A/V preamp- processor has balanced XLR subwoofer line-out connections, you may connect a Balanced XLR male connector to the XLR female input. Otherwise, ignore this connector. Do not use a combination of RCA and XLR input or output connectors.

Step 1A:

HIGH LEVEL INPUT: Use these “speaker-level” or high-level 5-way binding post connectors only if your receiver or preamp lacks a dedicated line-level subwoofer output jack. Connect speaker cables from your amplifier’s left-channel and right-channel speaker output binding posts to the high-level inputs using banana plugs (single or dual), spade connectors, pins, or bare cable if you wish (unscrew the top of each binding post and insert the cable into the hole in the post; tighten the knurled knob against the cable). Run a second pair of speaker cables from these jacks to your main left and right front speakers. Do not use these connectors if you are already using an RCA or XLR line-level connection from the receiver or preamp to the subwoofer. NOTE: BE SURE TO CONNECT BLACK TO BLACK

AND RED TO RED.

Step 2:

LINE OUT (RCA and XLR Balanced):

An RCA line-level (female) output and balanced XLR output (male) are provided for connection to a second subwoofer. Use a standard shielded coaxial cable for connection of the RCA Line Out to the second subwoofer. If you are using balanced XLR connectors, then use the balanced Line Out for operation of a second EP125 & EP175.

Step 3:

CROSSOVER: if you are using the Bass Management crossover menu settings in your A/V receiver or processor, turn this control to 120Hz.

If you are using the HIGH LEVEL (Speaker Level) binding-post inputs, set the crossover to 90 Hz for initial setup (12 o’clock). If you have floor-standing speakers (M50, M60, or M80), try a 60 Hz crossover frequency. If your main speakers are bookshelf models M3 or M22, try the 90 Hz setting. Ultimately you want to use a crossover frequency that produces the smoothest blend of sound between the subwoofer and your main speakers.

Step 4:

VOLUME: Set this midway to the 12 o’clock position for initial setup. You can use this to manually regulate the subwoofer volume at any time and during your initial setup adjustments with the other speakers in your stereo or home theater system.

Step 5:

AC VOLTAGE SETTING: Your subwoofer is supplied with a voltage switch set for use with 100 - 120 volts from the A/C line. The cover can be easily removed and switched over to set your EP125 or EP175 to 220 volts from the A/C line.

Once you have made appropriate connections from the A/V receiver or preamp/processor to the EP125 or EP175 and set the voltage switch to the proper voltage, find a nearby AC wall outlet and connect the main power cord to the three-wire socket at the bottom of the control panel. Move the power switch to the ON setting and the LED POWER indicator should glow Green. Leave the switch at the ON setting unless you go away for an extended period. Moving it to OFF will shut down all power to the subwoofer.

Step 6:

0 & 180 PHASE: This synchronizes the in/out movement of the subwoofer cone driver with the other speakers in your system. Once you have chosen the best location for your subwoofer, try flipping the phase switch between 0 and 180 to see if one or the other setting produces deeper and smoother bass output in your room. Leave the switch at the setting that results in the smoothest and deepest bass at several listening locations in the room. If you hear no difference, leave the switch at the 0 position. Quite often the phase switch makes no difference, but it’s dependent on your room and subwoofer location.

POWER INDICATOR: The LED Power indicator glows Green when it’s on and Red indicating Standby Mode.

Please Note: The EP125 or EP175 will shut down if heavily over driven into distortion. To reset, turn the power switch OFF then ON.
