Configuring the speakers (DTR-6.4)

Calibrating the speaker levels

Use this 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 menu are vital to create the proper sound space and dynamics.

These settings cannot be made when the sound is muted, when you connect the headphones, and when you use multichannel playback.

This unit supports the THX format and the test tone is output at standard 0 dB (the Absolute Volume value is 82). If you usually enjoy listening at lower level than the test tone, be careful of the test tone’s sudden big sound. Note that the test tone will be output immediately after pressing the ENTER button in the step 1 below.

1. Use the Calibrating the speaker levels and Manual background cursor buttons to select “4. Level Calibration” on the main menu and then press the ENTER button.

The “Level Calibration” menu appears.

You will hear 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 (82).

(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” menu will be disabled.

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.

Using the remote controller

1. Press the Test button.

You will hear a pink noise which will be emitted from the front left speaker. At this time, the volume of the pink noise will automatically increase to a predetermined reference level (82).

(1)

Remember the volume level of this noise and then press the CH

 

Sel button. The DTR-6.4 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 was emitted from the front left speaker.

(3)

Press the CH Sel button again. The DTR-6.4 will now emit the

 

pink noise from the front right speaker.

(4) Use the CH Sel button to select other speakers and adjust the

volumes until all speakers are adjusted to the same level.

The pink noise level can be adjusted to anywhere between –12 and +12 decibels for all speakers in 1-decibel increments. For subwoofer, values between –15 and +12 dB can be set.

2. Press the Test button to complete the procedure.

Note:

Speakers that you selected “No” or “None” for in the “Speaker Config” menu will be disabled.

2. Use the Manual background and Manual background cursor buttons to select “Left.”

(1) Remember the volume level of this noise and then press the Manual background cursor button. (Note that this can be adjusted to any level between –12 and +12 decibels in 1-decibel increments. For subwoofer, values between –15 and +12 dB can be set.) The DTR-6.4 will now emit the pink noise from the center speaker.

(2)Using the Manual background and Manual background 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 Manual background cursor button again. The DTR-6.4 will now emit the pink noise from the front right speaker.
