Axiom is deeply committed to ongoing audio research that continues to enhance the performance of our products. We design and engineer all of our loudspeakers based on the world-class psycho-acoustical research that was conducted at the National Research Council and that I have been an integral part of since its early years. This research changed the way that sound is measured, and allows Axiom to provide the world’s most realistic-sounding loudspeakers at amazing value to the consumer. By emphasizing the practical side of our ongoing research, Axiom continues to extend people’s expectations of performance.

It is our central goal at Axiom to turn this research into a truly exciting experience for you in your environment. Our commitment to the delivery of the most accurate sound reproduction is a commitment to heighten the level of enjoyment you receive from music and movies.

We at Axiom see our customers as family members and as such we stand at the ready to deliver personal, expert advice and to follow up on any of your audio needs.

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 Selector” set for use with 115 volts from the A/C line. The Voltage Selector can be easily switched over to set your EP125 v2 or EP175 v2 to 230 volts from the “Voltage Selector”.

Once you have made appropriate connections from the A/V receiver or preamp/processor to the EP125 v2 or EP175 v2 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:
ACTIVE / DEACTIVE SWITCH:
This switch at the top of the Amplifier panel controls the operation of the AUTO ON/OFF circuit that puts the subwoofer into the Standby mode when no signals are detected from your AV receiver or DVD player.

Leave the switch in the ACTIVE position if the AUTO ON/OFF functions normally and turns the subwoofer on (Green LED) when you are using your system and puts it in the Standby mode (Red LED) when you turn off your home theater system. If your subwoofer seems reluctant to turn on even after you increase the subwoofer signal level in your AV receiver, or you find the subwoofer turning off during very quiet music or low-volume playback, move the switch to the DEACTIVE position. This will bypass the Auto On/Off circuit so that your subwoofer will remain active even during quiet or low volume playback.

Step 7:
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.
