• Check that personal computers or other digital components connected to the same power source are not causing interference.

• To route more signal to the subwoofer, set it to PLUS or set the front speakers to SMALL (see Speaker Setting on page 85).

• The speakers may be out of phase. Check that the positive/negative speaker terminals on the receiver are matched with the corresponding terminals on the speakers (see Connecting the speakers on page 18).

• If applicable, check that the lowpass filter switch on your subwoofer is off, or the lowpass cutoff is set to the highest frequency setting. If there is a PHASE setting on your subwoofer, set it to 0º (or depending on the subwoofer, the setting where you think it has the best overall effect on the sound).

• Make sure that the multichannel analog inputs are selected (see Selecting the multichannel analog inputs on page 43).

• This is not a malfunction of the receiver. The scan function of your player alters the digital information, making it unreadable, resulting in noise being output. Lower the volume when scanning.

• Make sure that the input signal type is set to DIGITAL (see Choosing the input signal on page 55).

• You can only make a digital recording from a digital source, and an analog recording from an analog source.

• If the source component has a digital volume control, make sure this is not turned down.

• If the HDMI input function is selected, sound is muted until exiting the HOME MENU.

Remedy

For FM broadcasts

• Fully extend the FM wire antenna, adjust the position for best reception and secure to a wall, etc.

• Use an outdoor antenna for better reception (see page 30). For AM broadcasts

• Check the digital output settings of your DVD player. Make sure that the DTS signal output is set to On.
