Yamaha RX-V457 Sound Field Parameter Descriptions, DSP LEVEL DSP level, INIT.DLY Initial delay

SOUND FIELD PARAMETER DESCRIPTIONS

You can adjust the values of certain digital sound field parameters so the sound fields are recreated accurately in your listening room. Not all of the following parameters are found in every program.

■DSP LEVEL (DSP level)

Function:	Adjusts the level of all the DSP effect sounds within a narrow range.
Description:	Depending on the acoustics of your listening room, you may want to increase or decrease the DSP
	effect level relative to the level of the direct sound.
Control range:	–6 dB to +3 dB

■INIT.DLY (Initial delay)

Function:	Changes the apparent distance from the source sound by adjusting the delay between the direct sound
	and the first reflection heard by the listener.
Description:	The smaller the value, the closer the sound source seems to the listener. The larger the value, the farther
	it seems. For a small room, set to a small value. For a large room, set to a large value.
Control range:	1 to 99 msec

	analog sources. The AUTO setting is effective only when BASS and TREBLE are set to 0 dB.
Choices:	AUTO, OFF
