Setting Up the S xover
•
Set the LEVEL, LOW and HIGH Output controls all the way down by turning them fully counter
clockwise.
•
Using two standard 1/4-inch phone cables, connect the your mixerʼs left and right output to the S
xoverʼs LEFT and RIGHT INPUT.
•
Use a “Y” cable with a 1/4-inch TRS (TIP RING SLEEVE) to two 1/4-inch TS (TIP SLEEVE) to
connect the Left and Right LOW Output to the power amp connected to the low frequency driv-
ers.
For a detailed wiring diagram for the 1/4-inch TRS "Y" cable see page 8 in this manual.
•
Use a second “Y” cable with a 1/4-inch TRS (TIP RING SLEEVE) to two 1/4-inch TS (TIP
SLEEVE) to connect the Left and Right HIGH Output to the power amp connected to the high
frequency drivers.
•
At this point connect the power amplifiers to the low and high frequency speakers following the
manufacturers recommended procedures outlined in their individual owner manuals.
•
Set the position of the RANGE switch so that the FREQ control is operating in the desired fre-
quency range. The Range control operates from 35 Hz to 800 Hz when the RANGE switch is out,
but with the RANGE switch in the frequency is multiplied by 10 times so the range becomes 350
Hz to 8 kHz.
•
Once the RANGE switch is properly set, use the FREQ control to set the crossover point between
the low and high frequency driver. Be sure to check with the speaker manufacturerʼs recom-
mended operating range for the individual drivers to avoid any serious damage that may result.
•
Now, plug in the AC/DC adapter while appling the “Golden Rule of Audio” to power up your sys-
tem.
IMPORTANT NOTE
: The “Golden Rule of Audio” - LAST ON / FIRST OFF
When running a loudspeaker system with one or multiple power amplifiers, it is highly recommended that you
follow the LAST ON / FIRST OFF rule. When powering up your sound system, turn your power amplifier on last.
When you power down your system, turn your power amplifiers off first. This will prevent any switching spikes
you may get from other gear in your system, and help prevent unnecessary pops that can sometimes cause
speaker damage.
•
Run a signal from your mixer( like from a CD or MP3 player) and adjust the output level so a
good signal is sent to the S xover. Now adjust the LEVEL control to about half way up.
•
Finally, set the LOW and HIGH controls to about half-way and adjust the levels with an RTA
(REAL TIME ANALYZER), like a Samson D1500, or use your ears to dial in the blend between
the low and high drivers.
