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 
and 
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.
