CLARITY M/CLARITY M STEREO User Manual

5. SUB-D Cable

A SUB-D-15 breakout cable is included with the Clarity M for connection to
external digital audio devices, as well as GPIO connection. 3 BNC connectors
accept signals from digital mixing consoles or from an audio interface via S/PDIF
by using the included BNC-to-RCA adapter (Stereo version has 1 BNC connector).
See Chapter 13 for pin assignment details.
To connect to an AES/EBU-based device, a BNC-to-XLR adapter will be necessary.
For surround sound use, 3 adapters will be needed. We recommend the Neutrik
NA2FBNC adapter for this purpose. One BNC-to-XLR adapter is included with the
Stereo model.
GPIO is connected via a dedicated 1/8" TS output and a stereo 1/4" TRS input.
These can be used, for example, to trigger Stop/Play or Measurement RESET
commands remotely.

6. General Operation

After the Clarity M has been mounted, audio connections have been made, and
power is supplied, press the 6th button to power the unit on.
Note – to turn the unit off, hold the 6th button for 2 seconds, which brings up
the power-off screen. You can either power off completely with the 6th button,
reboot with the 5th button, or cancel the request with the 4th button.
Main Section
The main meter graphic on the left side of the screen can be viewed in either
LM6 Loudness Radar, RTA (Real Time Analyzer), or Vector Scope, depending on
your audio environment. The RTA view is ideal for monitoring short-term results
across the full frequency spectrum, while Radar view is great for long-term
results. The Vector Scope can help identify important stereo balance and phase
issues in your mix. Pressing the 3rd button flips between the 3 types of metering.
Radar
The loudness radar meter is ideal for simultaneously monitoring short-term
loudness (S) history on the scope and momentary loudness (M) on the outer ring.
The momentary loudness of your signal is based on a sliding 400 ms window,
which makes it a valuable aid in setting initial levels when you start a new mix.
The short-term loudness overview is especially important to keep an eye on
when mixing material on the fly, as it responds quickly when you adjust your mix,
making it a helpful indicator of where your loudness is in relation to the
target value.

Press the 1st button to start or pause the loudness measurement. True-peak and
correlation will continue to be measured. The 2nd button provides a global reset,
and will reset all values across Clarity M. By default, the rotary knob adjusts the
radar speed, but can be changed to adjust resolution or target loudness in the
System (SYS) menu.
(1) The multicolor graphic shows short-term loudness history (S).
The colors (black, blue, dark green, light green, orange) mark the transition
between the circular rings. The short-term loudness values of these rings are
determined in the Edit Menu's Radar Resolution parameter.
The 2nd ring (see callout #4) is always Target Loudness. The distance
between the other rings is determined by the Radar Resolution parameter in
the Edit Menu.
Example:
Radar Resolution is set to 12 dB.
Target Loudness is set to -24 LUFS.
Ring 1 (Outer Ring) is -12 LUFS
Ring 2 (light green to orange) is -24 LUFS
Ring 3 (dark green to light green) is -36 LUFS
Ring 4 (blue to dark green) is -48 LUFS
Ring 5 (black to blue) is -60 LUFS
(2) The outer ring displays momentary loudness (M).
The lights on the ring go from blue to green according to the Momentary
Range parameter. This parameter relates to the Target Loudness setting.
If Target Loudness is -24 and Momentary Range is set to -9 LU, the outer ring
will go from blue to green at -33 LUFS. Since the numbers follow the ring,
this will always happen at the 9 o'clock position.
The lights go from green to orange according to the Target Loudness.
If Target Loudness is set to -24 LUFS, the ring goes from green to orange at
-24 LUFS.
(3) True-peak indicator lights during peaks.
(4) Target loudness appears at the top of the ring and in the 2nd radar ring
(between green and orange measurements).
(5) The Loud indicator lights up when the Loud Alert level is reached. This is set
in the Edit Menu as a distance from the target loudness.
If target loudness is set to -24 LUFS, and Loud Alert is set to 6 LU, the Loud
indicator with light when the signal reaches -18 LUFS or louder. The Loud
Alert setting is also indicated in the outer ring by red numbers.
