Integra DTR-7.3 instruction manual Level Calibration Sub-menu, Calibrating the speaker levels

Speaker Setup

1-3. Level Calibration Sub-menu

Use this sub-menu to set the volume for each speaker so that each volume is heard by the listener at the same level. This is especially important for speaker layouts where the left and right speakers are at different distances or in asymmetrical positions due to room designs and configurations. These settings and the distance settings performed in the Speaker Distance Sub-menu are vital to create the proper sound space and dynamics.

Note:

The speaker level settings here are not effective for multi-channel input sources. To adjust the speaker levels for multi-channel input sources, you will need to use the CH Sel, Level , and Level buttons on the RC-514M remote controller. See page 33.

Calibrating the speaker levels

(1)When this sub-menu is entered, the DTR-7.3 will emit a pink noise from the front left speaker. At this time, the volume of the pink noise will automatically increase to a predetermined reference level (0dB). Remember the volume level of this noise and then press the cursor button. (Note that this can be adjusted in 1-decibel increments.) The DTR-7.3 will now emit the pink noise from the center speaker.

(2)Using the and cursor buttons, adjust the volume level of the noise from the center speaker so that it is at the same level as that was emitted from the front left speaker. You can jog back and forth between the speakers to help you compare the volume levels.

(3)Press the cursor button again. The DTR-7.3 will now emit the pink noise from the front right speaker.

(4)Repeat steps (2) and (3) above for the front right and other speakers until all speakers are adjusted to the same volume level.

Notes:

•Speakers that you selected “No” or “None” for in the Speaker Config Sub-menu will not appear.

•To accurately set the output levels, it is recommended to use a handheld sound pressure level (SPL) meter. Set the meter to C- weighting and slow averaging. A Radio Shack® SPL meter or equivalent is recommended. Using the internal channel noise generators, set each channel so that you read a 75 decibel sound pressure level.

a. Left

Sound comes from the front left speaker. Adjust the sound level between –12 and 12 decibels in 1-decibel increments.

b. Center

Sound comes from the center speaker. Adjust the sound level between –12 and 12 decibels in 1-decibel increments.

c. Right

Sound comes from the front right speaker. Adjust the sound level between –12 and 12 decibels in 1-decibel increments.

d. Surr Right

Sound comes from the surround right speaker. Adjust the sound level between –12 and 12 decibels in 1-decibel increments.

e. Surr Back R

Sound comes from the surround back right speaker. Adjust the sound level between –12 and 12 decibels in 1-decibel increments.

f. Surr Back L

Sound comes from the surround back left speaker. Adjust the sound level between –12 and 12 decibels in 1-decibel increments.

Note:

If the Surr Back/Zone 2 setting in the Surr Back/Zone 2 Sub-menu of the Hardware Setup Menu is set to “Zone 2,” then the Surr Bk R and Surr Bk L settings will not be displayed.

g. Surr Left

Sound comes from the surround left speaker. Adjust the sound level between –12 and 12 decibels in 1-decibel increments.

h. Subwoofer

Sound comes from the subwoofer. Adjust the sound level between

–15 and 12 decibels in 1-decibel increments.

Using the remote controller

1. Press the Test button.

You will hear a pink noise will be emitted from the front left speaker.

(1) Remember the volume level of this noise and then press the CH Sel button. The DTR- 7.3 will now emit the pink noise from the center speaker.

(2) Using the Level / buttons, adjust the volume level of the noise from the center speaker so that it is at the same level as that that was emitted from the front left speaker.

(3)Press the CH Sel button again. The DTR-7.3 will now emit the pink noise from the front right speaker.

Use the Level / buttons to adjust the volume of the noise from the front left speaker so that it is the same level as that that was emitted from the center speaker. The pink noise level can be adjusted in 1-decibel increments.

(4)Use the CH Sel button to select other speakers and adjust the volumes until all speakers are adjusted to the same level.

2. Press the Test button to complete the procedure.
