USING THE S170i

ADJUSTING THE VOLUME

Use the HTR 2 remote’s <Volume up/down> keys to adjust the “master volume” of the S170i, raising or lower all channels together.

NOTE THAT:

•A momentary keypress will change the master volume by 1 dB increments; if you hold down <Volume up/down> the master-volume change will “run-on” until the key is released.

•The S170i’s OSD will show the volume setting as a line graphic relative to the reference level (the “+” mark on the line), with a numeric display above in dB relative to the reference level. (If the <Display setup> <Temporary disp.> item is set to “Off” the momentary volume indication will NOT appear.)

Since recordings vary considerably in overall average level, there is no imperative to listen at the reference level or any other particular setting. A setting of -20 may sound “as loud” from one CD as -10 does from another.

•If muting has been activated (below), increasing the master-volume via the HTR 2 remote’s [Volume up/down] keys or the front-panel knob automatically releases the mute function; decreasing volume retains muting.

•The S170i will power-up/return from Standby mode at whatever master volume setting was last used; however, if the prior setting was greater than -20 dB the S170i will power up to -20 dB. This prevents inadvertently beginning a session at excessive volume.

MUTING THE SOUND

Use the HTR 2 remote’s <Mute> key to silence all channels completely. Muting is always available, regardless of source or listening mode selections.

NOTE THAT:

•Cycling through Standby or powering off releases muting; the S170i will always power up or return from Standby with muting off.

•Changing input or listening-mode selections does not release muting.

•Increasing the master-volume via the HTR 2 remote’s [Volume up/down] keys or the front-panel knob automatically releases the mute function; decreasing volume retains muting.

SETTING LISTENING MODES

ABOUT THE S170i’S LISTENING MODES

The S170i preamplifier offers seven distinct listening modes, tailored for different types of recordings or program material.

MONO

All output is directed to the center channel or left and right channels if there is no center channel present or selected; low frequencies are directed to the subwoofer if one is present in the Speaker setup

Mono mode is best selected for monaural recordings originally produced in single-channel format, including classic films and historic music recordings. It ensures a stable, clear monaural presentation with correct bass management.

STEREO

Stereo recordings, whether in PCM/digital or analog form and wither surround-encoded or not encoded, are reproduced as recorded; multichannel digital recordings (Dolby Digital and DTS) are reproduced via the left- and right-front channels only, as Lt/Rt (left/right-total or “Downmixed”) signals.

Select Stereo mode for listening to stereo recordings when you do not wish surround-sound to be in effect, or for multichannel recordings when only two-channel playback is possible (or desired).

DIRECT (DOLBY DIGITAL/DTS SOURCES ONLY)

Multichannel digital recordings (Dolby Digital or DTS) are reproduced via only the channels employed in the original recording. For example, a “5.1-channel” Dolby Digital 3/2/1 recording will reproduce via the front left-center-right, surround-left/right, and subwoofer speakers; a Dolby Digital 2/0/0 recording will reproduce via only the front-left and -right speakers (and he subwoofer if these were set to “Small” on the <Speaker setup> OSD menu.
