CONFIGURING THE S170

CONFIGURING LEVELS

From the OSD Main menu, select the <Level setup> item using the remote's [Cursor up/down], and [Enter]

keys. Activate the test-noise signal with the remote's [Test] key (third from the bottom); you will here a

"surf" noise that cycles through your speakers, beginning with the left-front. (If you do not hear the test-

noise, check your Audio Connections (above), and your <Speaker setup> OSD menu settings, (above.)

On the left-most column of the OSD you'll see an > pointing toward <Left> (if the > points to another

other line, use the remote's [Cursor up/down] keys to move it to <Left>). Now use the remote's [Cursor

<>] keys to adjust the level of the noise output from the Left (left-front) speaker; the test-noise will

automatically move there and the "level offset" reading on the right will change by 0.5 dB increments. If

you are using an SPL meter, adjust the Left output to produce a reading of 75 dB SPL C-weighted (or

whatever other reference level you have chosen to adopt).

If you are balancing levels "by ear" you will have to choose one speaker—usually the center—as a

reference and adjust each of the others so that is " sounds as loud" as the reference.

Using the remote's [Cursor up/down] and [Cursor <>] keys, adjust each speaker in turn to produce the

same SPL meter reading (or subjective loudness), within ±1 dB or better; the S170's ability to calibrate

outputs by 0.5 dB steps should facilitate this precision.

NOTE THAT:

• All speakers must be in their final locations before level-setting.

•Your subwoofer (if any) should be set with its integral crossover defeated, or set to its highest-possible

frequency if you are using the S170's SUBWOOFER output.

• Due to the effects of room acoustics, matched-pair speakers (front; surround; back) will not always

calibrate to exactly the same level offset readings.

• If you are particularly meticulous, you may wish to come back and re-check your level setup after

completing the Delay setup routine (below).

DELAY SETUP

Your system's channel-delay settings are a subtle but important refinement of your setup. By informing the

S170 of the loudspeaker-to-listener dimensions of each speaker, it will automatically impose the correct

delays for each channel, optimizing imaging, intelligibility, and surround-sound ambience. Enter your

dimensions with precision within about 1 foot/30 cm.

CONFIGURING DELAYS

From the OSD Main menu, select the <Delay setup> item using the remote's [Cursor up/down], and [Enter]

keys. Using the [Cursor <>] keys, set <Right> to the distance between your principal listening position and

the front surface of the front-right loudspeaker.

Using the same remote keys, set the remaining speakers, each to the distances of your system layout.

Where a particular speaker is not present in your system, "None" will be displayed and no distance setting

will be possible.

SOURCE SETUP

The S170 is equipped with nine total inputs: six audio-video inputs (labeled on the rear panel VIDEO1-6),

and 3 audio-only inputs (labeled CD, AUX, and TUNER). There is also an audio-only TAPE MONITOR loop.

For each input position of the S170, you may select a digital input to become active whenever that input

is selected, and you may assign a 7-character name which will be displayed on the front-panel display and

momentarily on the on-screen display whenever that input is selected.

CONFIGURING SOURCES

From the OSD Main menu, select the <Source setup> menu item using the remote's [Cursor up/down],

and [Enter] keys. Using the [Cursor <>] keys, call up the source you wish to configure. Sources are

numbered 1-9, which correspond in order to VIDEO1-6, CD, AUX, and TUNER on the rear panel (the TAPE

MONITOR loop is not configurable, and will not appear in the rotation). Use the [Cursor] (down) key to

move to the <Title> menu item, and press the [Enter] key. You may now edit the default title (“Video 1”,

“CD,” etc.) to a more meaningful name, up to 7 characters. The [Cursor up/down] keys scroll through the

complete list of available characters, while the [Cursor <>] keys move left and right across the six characters

(you may back up and change characters freely). When you are finished with the title, press [Enter] to

return to the <Source setup> menu.
