Read instructions - All the safety and operating instructions should be read before the product is operated. 2. Retain instructions - The safety and operating instructions should be retained for future reference. 3. Heed Warnings - All warnings on the product and in the operating instructions should be adhered to. 4. Follow Instructions - All operating and use instructions should be followed. [. . . ] The “level offset” reading on the right will change by 1 dB increments; ±12 dB adjustment is available. NOTE If you are balancing levels “by ear”, choose one speaker—usually the center—as a reference and adjust each of the others in turn to “sound as loud” as the reference. Be sure that you remain in the primary listening position while balancing all channels. To produce the same SPL meter reading (or subjective loudness), use the remote’s [D/F] keys to adjust each speaker. NOTES • All speakers must be in their final locations before level-setting. • Your subwoofer (if any) should be set with its integral crossover defeated, or if undefeatable, set to its highest-possible frequency if you are using the T 187's Subwoofer output. Final subwoofer-level adjustment “by-ear, ” using music and film sound material, is frequently useful. • Due to the effects of room acoustics, matched-pair speakers (front; surround; back) will not always calibrate to exactly the same level offset readings. You can exit ‘Test’ mode at any time by pressing [A] key, bringing you back to ‘Speaker Setup’ menu. You can also press the [TEST] key to discontinue the ‘Test’ mode. In addition to the Volume knob, use the HTR 8’s [VOL D/F] to adjust the “master volume” of the T 187 raising or lowering the channels altogether. A momentary keypress will change the master volume by 1 dB increments. If you hold down [VOL D/F], the master-volume change will “run-on” until the key is released. Since recordings vary considerably in overall average level, there is no imperative to listen at any particular master-volume setting. A setting of -20 dB may sound “as loud” from one CD or DVD as -10 dB does from another. The T 187 will power-up from Standby mode at whatever master volume setting was last used; however, if the prior setting was greater than –20 dB, the T 187 will power up at –20 dB. MUTING THE SOUND Use the HTR 8’s [MUTE] key to silence all channels completely. Muting is always available regardless of the source or listening mode selections. NOTES • Changing input or listening-mode selections does not release muting. • Adjusting the volume level via the HTR 8 or the front panel volume knob will automatically release the mute function. SPEAKER DISTANCE Your system’s speaker distance settings are a subtle but important refinement of your setup. Informing the T 187 of the loudspeaker-to-listener dimensions of each speaker automatically imposes the correct delays, optimizing imaging, intelligibility and surround-sound ambience. SETTING SPEAKER DISTANCE While at ‘Speaker Distance’ menu, use the [D/F] keys to individually set Front Left, Center, Front Right, Surround Right, Back Right, Back Left, Surround Left and Subwoofer to the distance measuring from your principal listening position to the front surface of their corresponding loudspeakers. [. . . ] • Center set to “OFF” on “Speaker Configuration” menu. • Center level set too low on “Speaker Levels” menu. • Source’s digital output is not connected to a T 187 digital input. • Source component not configured for multichannel digital output.
