Yamaha YSP-40D Manual Do Utilizador

You can adjust the sound beam output level of each channel by using the test tone or the audio output being played back 
in each beam mode to achieve a more true-to-life surround sound experience.

You can use the test tone feature to output a test tone from 
each channel to manually balance the channel levels.
Use this to set the channel levels so that the volume level 
of each channel is identical when heard from your 
listening position.

“TEST FRONT L” appears in the front panel display 
and a test tone is output from the front left channel.

The front panel display changes as follows:

“TEST SWFR” is only available when a subwoofer is 
connected to this unit and SWFR is selected for BASS OUT 
in SOUND MENU (see page 87).

Control range: –10.0 dB to +10.0 dB
