SYNCHRONISERS, DELAYS & SILENCE DETECTORS - RB-DS2

Volume

This selection shows the Volume sub-menu. The sub-menu items are INPUT PK DIGITS,

OUTPUT GAIN, ANALOGUE MUTE and DIGITAL MUTE.

Input Peak Digits

This option sets the full-scale dB input amplitude that will give full-scale digits in the digital

domain i.e the absolute maximum analogue input level that can be put into the unit before

digital limiting will occur.

From the volume sub-menu select INPUT PK DIGITS. The available options are +12 dB, +18

dB and +24 dB. The default value for input peak digits is +12dB.

Output Gain

This option is directly related to the Input Peak Digits; it sets the full scale digits on the

output of the unit. It can be used to apply gain to the input signal provided that the input

peak digits are set lower than 24 dBu or attenuation if required.

For an illustration of how the values relate please see the table below:

Input Peak Digits (dBu) Output Gain (dBu) Eective Gain (dBu)

12 6 -6

12 12 0 (unity gain)

12 18 6

From the volume sub-menu select OUTPUT GAIN. The available gain settings are from –6 dB

to +24 dB in 1 dB increments. The default value for output gain is +12dB.

Analogue Mute

This option mutes the analogue audio output. From the volume sub-menu select

ANALOGUE MUTE. The available options are OFF and ON. By default, the analogue mute

is o.

Digital Mute

This option mutes the digital audio output. From the volume sub-menu select DIGITAL

MUTE. The available options are OFF and ON. By default, the digital mute is o.

Setups

This selection shows the Setups sub-menu. The sub-menu items are VIEW, LOAD, SAVE

and REMOTE LOADING. Setups provide an easy way of saving and recalling congurations

settings. There are 8 available setups and each one includes the following parameters:

Mode (normal or extended),

Source (analogue, analogue sync or digital),

Channels (mono, dual mono or stereo),

Sample rate (32kHz, 44.1kHz, 48kHz, 64 kHz, 88.2kHz or 96kHz),

Sample width (16bit or 24bit),

Format (24fps, 25fps, 30fps or 30 drop frame),

Delay units (samples, elds, frames, time or metres),

Delay,

Input peak digits (+12dB, +18dB or +24dB),

Output gain (-6dB to +24dB),
