Setup & Operation

Signal Over Segments

Each channel has two red Signal Over Segments labeled OVER. The threshold and hold
characteristics of each segment are independently selectable using the Meter Overload
Light Menus (SETUP/MORE.../METER/OVRLD_1 or 2). The threshold for over segment #1
can be set for 1 to 4 consecutive over samples. The threshold for over segment #2 can be
set for 0 to 3 consecutive over samples beyond the segment #1 setting. When hold is
turned off, the over segment has the same hold parameters as the rest of the meter. When
hold is turned on, the over segment is held until reset.

Peak Extension/HDCD Limiting Meters

The Peak Extension/HDCD Limiting Meters are two rows of six red LEDs which indicate the
6 dB of extended range available when in HDCD Peak Extension or HDCD Limiting Mode.
The meters are only active when monitoring HDCD 16-bit signals using Peak Extension or
HDCD Limiting during recording, and signals with Peak Extension during playback. The six
LED's illuminate from right to left, with each LED indicating 1dB of limiting. The full range
of the Peak Extension/HDCD Limiting Meters will illuminate after the amber 0 dB LED's and
before the red Over LED's on the Signal Level Meters.
For more information on Peak Extension and HDCD Limiting, see "Creating the 16-bit HDCD
Release Sound You Want" on page 35 in this section and page 69 in the Reference section.

Meter Reset Button

The Meter Reset Button is used to reset a held meter indication such as peak level or
overload.
