Ecler DVA SERIES - Manual (Page 5)

5
The DVA1-5c / DVA2-10c operates under voltages between 90 and 264 V at 47 to 63 Hz.
This devices features an over dimensioned power supply that adapts to the mains voltage in any
country of the world with no need to make any adjustments.
The power consumption of the DVA1-5c and DVA2-10c is very low, so they don't need any
cooling, but you should avoid extreme temperatures and the atmosphere should be as dry and
dust-free as possible.
In order to protect the unit from an eventual electrical overload it carries a 500mA fuse
(10). Should it ever blow up, unplug the unit from mains and replace it with an identical one. If the
new fuse blows again contact immediately with our Authorized Technical Service. YOU MUST
NEVER USE A HIGHER VALUE FUSE.
3.2. Connectable video sources
ECLERs video accessories accept any composite baseband video signal under one colour
standard (PAL, NTSC or SECAM)
Video Cassette Recorders (VCRs)
The video signal should be taken from the corresponding output and be connected to the
input(s) via a 75 Ohm impedance coaxial cable with BNC connector at the, DVA1-5c (6) or
DVA2-10c (17-14) end. The normalized nominal video level is 1Vpp.
The corresponding audio inputs connect to the RCA sockets DVA1-5c (8-13) or DVA2-10c
(19-27) (16-23). The audio connections should be done with shielded audio cable using RCA (Cinch)
type connectors.
Cameras
The connection of video cameras is similar to that of VCRs. It's necessary that the camera
provides separate audio and video outputs.
Monitors and video projectors
The connection is also similar to that of VCRs, connecting video and audio separately.
3.3. Connectable audio sources
Any unbalanced audio signal may be input. This input has a unity gain, i.e. the incoming
audio signal is not modified unless you use the GAIN ADJ control with ±6dB range found on the
DVA1-5c and DVA2-10c.
3.4. Start up
Power up the unit by pushing the switch labelled POWER (5) and the pilot-light inside the
switch will light up, indicating that the unit is functional. These units are highly reliable, bear in mind
that a not perfect quality may be caused by poor quality cables.
The DVA2-10c features an extra switch (24) located on the back panel which selects the
operating mode: either 1 input and 10 outputs or 2 x 1 input and 5 outputs independent.
