SPEAKER CONFIGURATION

SETTING LEVEL TRIM

Press the HTR L73 remote’s “TEST” key, activating the L73’s channel-balancing test signal and displaying the <TEST TONE> menu on the OSD. You will hear a “surf” sound that cycles through your speakers, beginning with the Front-Left. (If you do not hear the test signal, check your speaker connections (above), and your <SPEAKER SETTINGS> OSD menu settings, (above.)

As the test signal cycles around the speakers, the OSD (and the VFL front panel display) will highlight the

currently playing channel. Now use the remote’s keys to adjust the loudness of the noise output from the currently playing channel to the required level (it’s usually simplest to begin with the left-front). The “level offset” reading on the right will change by 1 dB increments; ±10 dB adjustment is available.

NOTE

•If you are balancing levels “by ear,” choose one speaker – usually the centre – 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.

•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 L73’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.

DELAY TIME

Your system’s SPEAKER CONFIGURATION settings are a subtle but important refinement of your setup. Informing the L73 of the loudspeaker-to-listener dimensions of each speaker automatically imposes the correct delays, optimising imaging, intelligibility, and surround-sound ambience.

SETTING SPEAKER DELAY TIME

From the OSD’s <AUDIO SETUP MENU> screen, select the <LISTENING MODE> item using the remote’s

and “Enter” keys. Using the keys, select the surround mode you wish to configure. From your principal listening position to the front surface of the centre loudspeaker select the amount of delay for that particular surround mode. The delay in milliseconds roughly represents the distance in feet; one millisecond is approximately one foot.
