EP350 v3 Amplifier
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.
Step 8:
ON/OFF AC POWER/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 EP350 v3 to 230 volts from the “Voltage
Selector”.
Once you have made appropriate connections from the A/V
receiver or preamp/processor to the EP350 v3 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 9:
TRIGGER IN (3.5mm MINI-Jack):
This is for any 8-Volt
to 18-Volt power-on trigger. It is also intended for trigger-
controlled operation with future Axiom products.
NOTE: THE
POWER SWITCH MUST BE OFF FOR THE TRIGGER TO
OPERATE.
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 EP350 v3.
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):
An RCA line-level (female) output is
provided for connection to a second subwoofer. Use a standard
shielded coaxial cable for connection of the RCA Line Out to
the second subwoofer.
Step 3:
VOLUME:
Set this midway to the 9 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 4:
X-OVER FREQUENCY:
If you are using the Bass Management
crossover menu settings in your A/V receiver or processor,
turn this control to 120 Hz to eliminate the EP350 v3 internal
crossover from the circuit.
If you are using the HIGH LEVEL (Speaker Level) binding-
post inputs, set the crossover switch to 80 Hz for initial setup.
If you have floor-standing speakers (M50 v2, M60 v2, or M80
v2), try a 60 Hz crossover frequency. If your main speakers are
bookshelf models M3 v2 or M22 v2, try the 80 Hz setting, for
the M2 v2 try 100 Hz. Ultimately you want to use a crossover
frequency that produces the smoothest blend of sound between
the subwoofer and your main speakers.
Step 5:
POWER INDICATOR:
The LED Power indicator glows Green
when it’s on and Red indicating Standby Mode.
