1. IMPORTANT REMARK
Congratulations! You are the owner of a carefully designed and manufactured equipment.
We thank you for having purchased a SVA1-5c, DVA1-5c or DVA2-10c Selector or distributor. It is
VERY IMPORTANT that you read this manual before connecting the device in order to obtain its
maximum performance.
We recommend our authorised Technical Services whenever any maintenance task
should be needed so that optimum operation shall be achieved.
1.1. Precautions
The DVA1-5c and DVA2-10c must be earthed through its mains cable.
Do not expose the unit to rain or water splashes, and do not place liquid containers or
incandescent objects like candles on top of the unit.
Should any connection / disconnection task be done, always disconnect the unit from the mains
supply.
There are no user serviceable parts inside the unit.
2. INTRODUCTION
The SVA1-5c reversible audio/video selector from ECLER features either one input and
five outputs or five inputs and one output. It consists of a passive device extremely useful in any
setup which requires selecting one of various video sources and/or various monitors, video
projectors, etc.
The DVA1-5c and DVA2-10c distribution amplifiers are a versatile accessory for every
setup which requires distribution of audio/video signals (VCR, cameras, etc.) to various monitors or
video projectors, ensuring minimal loss, maximal audio/video quality and a guaranteed reliability.
The DVA1-5c features one video input, one stereo audio input, five video outputs and five
stereo audio outputs, with general adjustments for the video, chrominance and audio signal.
The DVA2-10c is in fact two DVA1-5c units stacked into one chassis and can be operated
as two totally independent DVA1-5c or as a single one input - 10 outputs distribution amplifier.
3. INSTALLATION
3.1. Placement and mounting
The SVA1-5c and DVA1-5c are minirack-sized units. However, with the PUM3 accessory,
two minirack modules (9,5'' x 44 mm) can be assembled together into one rack unit (19''). With the
PPM1 and PUM3 accessories you can rack-mount one minirack-sized module.
The DVA2-10c distribution amplifier has a standard rack size (19'', 1U). All these devices
can therefore be mounted into standard rack cases.
As a general rule of thumb, all connections should be held as short as possible using high
quality cables and connectors in order to avoid noise and signal attenuation. Always try to place the
device as far away as possible from noise sources (dimmers, engines, etc...) and mains wires. For
the very same reason, and under any circumstance, should you ever remove the unit's metallic
cover.

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 (SVA1-5c no
consumption at all), 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
(17). 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 SVA1-5c (7(13)),
DVA1-5c (10) or DVA2-10c (24-21) end. The normalized nominal video level is 1Vpp.
The corresponding audio inputs connect to the RCA sockets (SVA1-5c (9-15(8-14))
DVA1-5c (12-20) or DVA2-10c (26-34) (23-30). 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 (6) and the pilot-light inside the
switch will light up, indicating that the unit is functional (DVA1-5c and DVA2-10c)
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 (31) 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.
3.5. Settings
These controls let you individually adjust the video (4), chrominance (5) and audio (2-3)
levels inside the DVA1-5c and DVA2-10c. These settings should only be modified by a qualified
technician, with the appropriate measuring instruments.

4. CONSIDERATIONS
4.1. Ground loops
Ensure at all times that no signal sources reaching the device and no devices connected to
its inputs have their earths interconnected; that is, earth should never reach them via two or more
different paths, as this could lead to humming which could even interfere with the video reproduction
quality. In order to avoid earth loops, ensure that the shieldings of cables, if connected to the
chassis, are never connected with each other.
4.2. Background noise
The use of active circuitry can yield, depending on the configuration, to a significant noise
level. The SVA1-5c, DVA1-5c and DVA2-10c distribution amplifiers have been designed for the
minimum possible noise. Anyway, the noise level will always depend on the correct use and
installation of the unit.
4.3. Cleaning
The control panel must not be cleaned with any dissolvent, abrasive or petroleum
derivated substance else paint and silk-printing could be damaged.
Whenever cleaning should be necessary use a soft cloth slightly wet with water and
neutral liquid soap. Be careful that no liquid gets into the unit. Never use sharp or erosive objects to
scratch the control panel.
Should any liquid get into the unit, do not use any cleaning sprays; send the unit to the
nearest ECLER Technical Service.
