Troubleshooting

Audible hiss at high volume settings

The input dynamic range of most current recordings is at maximum

16 bit. The reason for this is that currently CD, DVD, and LaserDisc

use a 16-bit standard, although DVD can support up to 24-bits. The

analogue sources you have cannot achieve this kind of range. For

comparison, analogue sources are likely to be of the order of:

• VCR, 12 bits.

• FM radio, 13 bits.

• Reel to reel tape, 13 bits.

• Cassette tape, 12 bits.

•LP, 11 bits.

Note: There may be a difference between the dynamic range of

the source channel when it is operating, and the noise you hear

in standby. For example, LP normally has lower noise when the

stylus is not in the groove; similarly tape will be quieter when it is

stopped. CD may also be quieter when it is stopped, producing so

called ‘digital silence’.

The G68 has a 24-bit capability on its internal analogue-to-digital

converter, which is used for analogue sources. When the volume is

turned up high you may hear its dither as a hiss when the sources

are stopped. This hiss is lower than the background noise of your

recordings and should be of no consequence.

Sound not clear

• If speech sounds muffled in a system with a centre speaker,

check that sound is coming from the centre as there may be a

connection problem. In a digital or Meridian feed to the centre

you may have set it up to be right instead of left so that it is

playing a subwoofer signal.

• If speech sounds muffled in a system with no centre speaker, you

may have selected a layout that expects one. See

Centre not working

There may be a connection problem.

• In a digital or Meridian feed to the centre, you may have set it

up to be right instead of left, and therefore it may be playing a

subwoofer signal.

There is a hiss when starting DTS LaserDiscs or CDs

The DTS audio stream is indistinguishable from a PCM audio

stream; the G68 takes 30ms to identify the encoding, during which

a hiss is heard.

• With non-video DTS sources you can add a 30ms delay to avoid

this.

• With video sources you can create a DTS-only source to avoid any

hiss.
