Help!
Standby point not lit
Check the following:
1. There is AC power connected to the socket on the rear of the 518
2. The power switch on the rear panel of the 518 is turned on
If the 518 will still not illuminate, check any fuses in your power supply
and the fuse in the inlet of the 518. If these are all intact, contact your
dealer.
Audible hiss at high volume settings
The input dynamic range of any recordings you have are at maximum 16
bit. The reason for this is that CD and other consumer sources use a 16
bit standard. The analogue sources you have cannot achieve this kind of
range. For comparison, analogue sources are likely to be of the order of:
•
FM Radio, 13 bits
•
Reel-reel tape, 13 bits
•
Cassette tape, 12 bits
•
LP, 11 bits.
Note that 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 518 has a 16 bit capability from input to output on analogue sources.
When the volume is turned up high you may hear this dither as a hiss
when the sources are stopped. This hiss is lower than the background
noise of your recordings and is of no consequence.
No output with Meridian 565, DSP speaker or DAC
Many consumer products will mute when fed a signal in Professional
format. If you have no sound – try setting Out to C.
No time display with Meridian DSP speaker
518 removes unnecessary subcode as a method of reducing jitter and
therefore improving sound quality.
Because 518 does not pass on subcode, the time display feature on
DSP5000 or DSP6000 becomes disabled. However the Meridian Comms
system keeps the speaker updated on the current track number.
Communications not working between 518 and other
Meridian products.
If you have this problem check the connections carefully.
Are you using a mix of 200 and 500 mode units?
