Tone Generator

Sets the test tone frequency for each of four tone
generators (Tone Generator 1 thru 4).

• Frequency Selection Lists

Selects the frequency 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, AES, or analog audio
channel sources into a stereo pair (Down Mix Left and
Down Mix Right), or selection of any two audio sources
to be mono-mixed to serve as a monaural source.

With an optional upmixer licensable feature activated,
any normal PCM stereo pair can be fed to the upmixer to
generate 5.1 surround sound audio which in turn can be
applied to six user-selectable channels.

• Down Mixer Selection

Separate drop-down lists for Left, Right, Center, Left Surround (Ls),
and Right Surround (Rs) inputs allow embedded, AES, or analog
channel 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 consists of basic L/R PCM signals with no

additional encoded information.
