Integra DTR-7.2 instruction manual Speaker Setup, Level Calibration sub-menu

Speaker Setup

1-3. Level Calibration sub-menu

Here you will set the volume for each speaker so that they are all 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 above are vital to create the proper acoustics required for the optimum sound space and dynamics.

Notes:

•Be aware that when you enter this sub menu, a loud white noise is output.

•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-461M remote controller. See page 52.

Calibrating the speaker levels

(1)

When this sub-menu is entered, the DTR-7.2 will emit a pink noise from the front left speaker. At this time, the Master volume automatically increases to the reference level (0dB). Remember the level of this noise and then press the cursor button. (Note that this can be adjusted to any level between –12 and 12 decibels in 1-decibel intervals.) The DTR-7.2 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 the same level as 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-7.2 will now emit the pink noise from the front right speaker.

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 intervals.

b. Center

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

c. Right

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

d. Surr Right

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