2.2.5.3 PD4216 Components
2.2.5.4 PD4216 Operation
At the interface, audio and control signals are separated. Audio facilities such as Mic output, Level
control, LS output and Headset control are wired to a 25 way D-type connector.
Control signals are relayed to the custom panel through a serial interface with a 15-way D-type
connector. DC power is supplied via this link, giving 15VA of lamp drive (e.g. 24 x 28V lamps/LEDs).
Further auxiliary audio and control inputs and outputs can be fitted to the interface with the installation
of an additional PDE4537 options card.
The remote custom panel utilises a number of cascaded PDE 3531/P/SL/D cards to make up the ports
for the required number of switches/lamps/displays.
2.2.5.5 PD4216 Controls and Indicators
One green LED indicator on the front panel illuminates when DC power is present.
2.2.5.6 PD4216 Installation Information
The microphone/s and volume pot/s should be wired with good quality 7/0.2 screened cable over a
maximum distance of 25m. Drake Technical support should be consulted regarding suitable
microphones and headsets.
The control interface can be connected to the remote panel with a cable run of up to 20m using 15-way
screened cable or 15-way screened ribbon cable.
Connection to the matrix is made by CAT5 connection, or 75
Ω
coaxial cable (50
Ω
BNC connectors) if
the PDE4536 options card is used.
