Parameter details

Peak meter on/off

The meter display shows both VU and peak metering (de-
fault) .
The meter display shows only VU metering . The peak me-
tering is not shown .

VU meter reference level

The default value is "0 dB" . You can select between "0
dB" and "+7 dB" in 1 dB steps .
<Example>: If you set the reference level to "+5",
the level at 0 VU is +5 dB higher than the refer-
ence level .

ence level appropriately when an external audio de-
vice connected to the outputs of the unit has enough
headroom . Normally, set it to "0" .
<Memo>: If you set the reference level other than
"0", "+" is lit beside the "0" position of the VU meter,
showing that the 0 VU level is not the reference level .
