OPERATING INSTRUCTIONS

DOLBY PRO-LOGIC AUDIO SYSTEM ALIGNMENT

The SSE 35 is for Dolby Pro-Logic systems, where Left,

Center and Right Channels should have matched response.

Though the SSE 35 helps a great deal, ±6 dB boost/cut may

not be enough to compensate between vastly different speaker

brands, models and designs. For best results, choose left,

center and right speakers that have a similar sound, and let the

SSE 35 do the “fine tuning.” Use a one-third octave real-time

analyzer and a sound pressure meter to “flatten” the system as

described in the analyzer or meter manual or the RaneNote on

“Home Theater Systems” included in this manual. Start with

the Center Channel first, then match the other Channels.

Use the Pro-Logic decoder’s NORMAL mode when using

the SSE 35. Normal mode directs all common or mono

information above 100 Hz from the Left and Right Channels

to the Center Channel.

SETTING UP THE CROSSOVER

When using one or two subwoofers, press both ENGAGE

switches in and the LEDs will light up. This routes the signal

through the crossovers and into the low frequency equalizer

to the separate subwoofer outputs.

When using one subwoofer or a pair or mono subwoofers,

set both SOURCE switches to L&R. When using stereo

subwoofers, set the SOURCE switches to LEFT and RIGHT

respectively.

Setting of the CROSSOVER FREQUENCY depends on

the type of speakers being used. Small left, center and right

speakers will not produce much bass in themselves, and

require the higher subwoofer setting of 125 Hz. Larger or full

range left, center and right speakers will sound better with the

setting of 80 Hz. You may wish to experiment and use your

ears to determine the best position for this switch. If the

subwoofer(s) have their own crossover, set the subwoofer's

crossover frequency as high as possible, allowing the 24 dB

crossover in the SSE 35 to do all the work.

If any THX

speakers are used for either mains or

subwoofer, use the 80 Hz setting. However, if a THX proces-

sor is being used, we recommend not using the crossover in

the SSE 35 and using the crossover in the processor — in this

case do not depress the ENGAGE switches or use the SSE 35

subwoofer outputs — connect your subwoofer to the proces-

sor directly.

The frequencies of the LEFT and RIGHT channels are not

affected by the low frequency equalizer when the ENGAGE

switches are depressed. This way, if the front speakers are

capable of producing bass they will do so — along with the

subwoofer.

SETTING CURVES USING THE SSE 35

Rane’s unique constant-Q circuitry makes setting curves

easy. With Rane graphic equalizers, for the most part what

you see is what you get — unlike previous equalizer designs

where the bandwidth changes with the slider positions. With a

constant-Q equalier, only frequencies within each band are

affected, allowing greater accuracy and control.

Place the speakers first, then analyze and equalize.

Referring to analyzer room curves, begin by positioning the

sliders to create the inverse curve shown by the instrumenta-

tion. Remember, most applications require only a few dB of

boost or cut. If more is required, use architectural and

mechanical means: change, add, remove, or relocate acousti-

cally sensitive items (speakers, drapes, carpets, mirrors, etc.)

as required.

USING THE BYPASS SWITCH

The SSE 35 provides an equalizer BYPASS switch &

indicator as a useful tool for optimizing settings. Use the

BYPASS switch for making quick “A-B” comparisons, that

is, comparing “A”, equalized (BYPASS out, LED off), versus

“B”, unequalized (BYPASS in, LED on). To do this freely,

without danger of system damage, you must first pay atten-

tion to how much equalization is being used. Try for an

average of 0 dB for all sliders in a channel.

Since the SSE 35 always operates at unity gain in the

BYPASS mode, comparison after a lot of boosting or cutting

can result in startling level differences. Therefore you want to

keep the system level down until you first use the BYPASS

switch. Be very careful the first time you use it.

The crossover remains active regardless of the position of

the BYPASS switch. Keep this in mind when making com-

parisons and listening to the subwoofer range. Only the

equalizers are bypassed.
