Operating Instructions
9305 Function Submenu List and Descriptions
Tone Generator
Sets the test tone frequency for each of four tone
generators (Tone Generator 1 thru 4).
• Frequency Selection Lists Selects the frequency independently for each of the four tone generators.
18 discrete sine wave frequencies are available, ranging from 50 Hz to
16 kHz (default frequency is 1.0 kHz).
Note: Unity-gain signal level is equivalent to -20 dBu.
Audio Mixing
Provides down-mix audio routing selections that
multiplexes any five embedded audio channel sources
into a stereo pair (Down Mix Left and Down Mix
Right). Also provides selection of any two embedded
channels to be mono-mixed to serve as a monaural
source for an embedded output channel.
With an optional upmixer licensable feature activated,
any normal PCM stereo pair of the 16 embedded
channels can be fed to the upmixer to generate 5.1
surround sound audio which in turn can be applied to
six user-selectable embedded channels.
• Down Mixer Selection Separate drop-down lists for Left, Right, Center, Left Surround (Ls),
and Right Surround (Rs) inputs allow embedded channel (or silence)
audio source selection for each of the five inputs as shown below.
The example below shows selection from various sources and the
resulting stereo pair DM-L and DM-R. The two signals comprising the pair
can be routed and processed the same as any other audio input source.
Note: The stereo pair are basic L/R PCM signals with no additional
encoded information.
