The example below shows a remote keyboard connected of the Digital Sprite 2:
Video switchers
Video switchers allow multiple Digital Sprites to be controlled from a single or pair
of monitors. This allows the flexibility of controlling up to 256 cameras from a
single location without having to purchase extra matrix equipment. The video
switcher routes the monitors from the Digital Sprite 2 being controlled to the
operator’s monitors, up to 16 control positions can have monitor switching.
The example below shows two Digital Sprites controlled from individual control
points. The video switcher routes the monitor outputs from the Digital Sprites to
the control points:
Ti p : Each 485-bus device is supplied with a 2m 485-bus cable. To extend the distance
between devices, two 485-bus junction boxes and 12v-power supply are re q u i red.
A total distance for the whole 485-bus network can be up to 1500m (4900ft).
Connecting Audio devices
Digital Sprite 2 can re c o r d and playback a single stream of audio linked to camera 1.
T h e re are two audio input ports: MIC IN and LINE IN, and an audio output: LINE OUT.
Connecting a microphone to MIC IN.
Connect the microphone into the 3.5mm jack plug labelled MIC IN. It is import a n t
to select the correct type of microphone for connection to the Digital Sprite 2.
Digital Sprite 2 re q u i r es an electret microphone with a sensitivity of –50dBV or
b e t t e r.
Connecting a pre-amplifier to LINE IN.
Where additional microphone gain and/or adjustable gain is required, an external
microphone pre-amplifier with adjustable gain is recommended. A microphone
pre-amplifier will provide a line level 1V pk-pk signal that can be connected to the
RCA socket labelled LINE IN on the Digital Sprite 2.
The line level input has the following specification:
Line IN 47kΩ input impedance, 1V pk-pk
Connecting the LINE OUT to an amplifier.
Connect the RCA socket labelled LINE OUT to an external amplifier or powered
loudspeakers.
The line level output has the following specification.
Line OUT 1V pk-pk
Recording audio
Once the microphone or pre-amplifier is connected to the Digital Sprite 2, the
option to record audio should be enabled in the menu. See page 23 for details
of enabling audio recording.
It is advised that you test the quality of audio playback, it may be necessary to
increase the gain of the microphone.
As the audio is linked to camera 1, it is required that camera 1 be viewed, either
in a full screen or in a quad view during playback to hear the audio.
