Setup & Operation
System Status Indicator
The System Status Indicator is a multi-color LED which shows system status. States dis-
played by the Indicator are shown below:
Off

The most common causes of system errors involve system synchronization which will also
extinguish one or more of the clock indicators. For example, a fatal error will result from no
digital input source in digital input mode. Nonfatal errors may appear momentarily when
switching from analog input to digital input mode or when changing meter or monitor
sources. Nonstandard operation refers to certain setup configurations which are consid-
ered to be nonstandard operating conditions. For example, setup configurations such as
44.1 kHz A/D conversion and 88.2 kHz to 44.1 kHz sampling frequency conversion using
fixed decimation filtering, and Software Download are considered nonstandard.
System Status Indicator, Clock Indicator, and HDCD Indicator brightness are adjusted by
selecting STATUS in the Front Panel Display Menu (SETUP/MORE.../SYSTEM/PANEL).
Clock Indicators
The Clock Indicators are two green LED's which indicate A/D and D/A clock status. Indica-
tions are as follows:
Green = Locked
Off
= Not Locked
HDCD Indicator
The HDCD Indicator consists of an LED back lit HDCD logo which lights when a 24-bit, 20-
bit or 16-bit HDCD digital signal is detected. HDCD Indicator states are as follows:
Off
= HDCD Code Not Detected
Blue
= HDCD Code Detected.
Amber = HDCD 16-bit Code Detected with Monitor Amplitude Decoding Off.
Blue indicates HDCD code is detected. Amber indicates HDCD 16-bit code is detected and
amplitude decoding at the monitor (D/A) output is turned off, or in a 44.1 kHz Digital
Input Mode, there is an HDCD 16-bit input signal, and input amplitude decoding is turned
off. HDCD 16-bit monitor amplitude decoding (MONHD16) can be turned on or off in the
Levels Menu (LEVELS), the Second Operating Menu (OPS 2), or the Monitor Setup Menu
(SETUP/MORE.../MONITOR). HDCD 16-bit input amplitude decoding can be turned on or off
in the Digital Input HDCD_16 Decoding Menu (SETUP/INPUT/HDCD_IN).
