BEFORE GETTING STARTED
IN GENERAL
When using your Van Medevoort product make sure that the following is observed:
-The cooling air vents are not covered
-The air can move freely around the product
-The product is sited on a vibration-free surface
-The product is not exposed to (very) high temperatures, cold, moist or dusty environments
-Do not expose the product to direct sunlight
-Do not expose the product to electrostatic discharges
-Never put any type of object directly on top of the product
When in doubt do consult your Van Medevoort dealer. If any object and/or water and/or moisture
should find its way into the unit, always disconnect the power cord by its plug, never by the cord itself.
When leaving for extended periods, e.g. holidays, we strongly recommend that you unplug all audio
equipment. This is also advisable when there is a thunderstorm or lightning.
CONNECTING
Before actually making any connections, always disconnect the power cord from the wall socket by its
plug, never by the cord itself, or switch the product OFF.
Always connect one source at a time and make sure that Left & Right channels are not interchanged.
Make sure that the plug is fitted correctly. Otherwise, hum and/or noise may be apparent.
DO NOT forget to read the respective manuals of the products you wish to connect to this product,
BEFORE connecting.
POSITIONING
If this product is being used at the same time as e.g. a Computer and/or a TV-tuner, you may
experience various anomalies. When this is the case, please follow these instructions:
-Position the product as far away as possible from this type of item
-Make sure that the tuner interconnect is detached as far away as possible from all radio and/or
TV power cords.
-Usually these anomalies occur when a 300 Ohms cable is used. We advise you to change to a
well shielded 75 Ohms cable.
CE MARKING
The CA470 is in conformity with the EMC directive and low-voltage directive.
A NOTE ABOUT RECYCLING
This product’s packaging materials are recyclable and can be reused. This product and the
accessories packed together are the applicable product to the WEEE directive except batteries.

1. ON / OFF Power switch.
LED indication control. Fully red when switched ON, 50% red when in STANDBY mode
(selected with the Van Medevoort Remote Control). Above the LED you will find the Infra Red
sensor for the Remote Control.
2. 1 –6 Source selector indicators.
These 6 push buttons correspond with the inputs on the backside of the amplifier. The LED’s
will go into flickering mode when the signal is switched to MUTE.
3. Volume Control.
Fully anti-clockwise sets the volume at its lowest level. Fully clockwise means that the volume
is at its maximum level. Please be aware that continuous play at this level can cause serious
damage, not only to the amplifier itself but also to any other equipment connected to it.

Technical Specifications
ONLY connect the amplifier to a (professionally installed) wall socket with earth or ground and
the corresponding voltage setting, as indicated on the back of the amplifier. Any faulty
connection will invalidate the warranty.
To prevent damage to your loudspeakers it is advisable, both at switching ON and OFF to turn
the volume control fully to the left. Fully anti-clockwise sets the volume at its lowest level. The
same applies when changing sources.
The correct order for ON/OFF switching of the various products is as follows:
ON: always first the source, then the pre-amplifier, followed by the power amplifier.
OFF: always first the power amplifier, then the pre-amplifier, followed by the source.
Only connect the DC and/or RC outputs of one product exclusively to the corresponding DC or
RC inputs of the other product. Do not connect crosslink wise and also not with any audio input
or output.
Do make sure that there is always enough ventilation around the amplifier in order for it to
remain at its desirable temperature level.
Do not put any magnetic devices near or on top of the amplifier, e.g. floppy disks. This can
cause irreparable damage to such devices.
If it is necessary to replace the fuses, use only Slow fuse(s) with the exact same value. The
fuse holders are positioned inside the amplifier and should only be replaced by an authorized
Van Medevoort Service Center. There are no user serviceable parts inside.
If you experience any problems, always contact your nearest authorized Van Medevoort
Service Center.

Problems caused by faulty connection will invalidate the warranty.
1. INPUT 1. As a standard feature the amplifier has one balanced XLR input, so as to make it a
perfect match with the XLR output of a source, e.g. a CD player.
2. INPUTS 2 –6. Suitable for all sources with RCA-cinch connectors as well as having an output
at line level. E.g. CD player, SACD player, D/A converter, Tuner, CD recorder, HDHT PC and
Media Player.
3. TAPE-OUT. To be connected to the input of a CD Recorder, HDHT PC or Media Player.
4. PRE-OUT. Outputs of the Pre-Amplifier, both RCA- cinch and XLR. To be connected to RCA-
cinch or XLR input(s) of the Power Amplifier(s).
5. DC and RC control. DC control can only be used with other Van Medevoort Power Amplifier(s).
One can only switch into STANDBY or ON, via the Remote Control.
RC control. The RC output can only be connected to the RC input of e.g. a tuner. Then the
tuner can be operated with the Van Medevoort Remote Control.
6. IEC-USA Power Chassis Connector. To be connected with the proper wall socket, which must
be earthed or grounded. Every Van Medevoort product is optimized for your country’s electrical
standards. e.g. 230V-50Hz or 115V-60Hz. This cannot be changed. Please check that your
product is set to the correct voltage setting BEFORE connecting to an AC power outlet.

On the backside of the amplifier you will find 2 rows of RCA-cinch inputs. The upper row is for the
LEFT channel and the bottom row is for the RIGHT channel.
For your convenience you will find a red sticker, indicating “phase”. The phase of your electricity
system can be determined with a voltage seeker.
The amplifier must only be cleaned with a cloth, impregnated with a Ph-neutral cleaning fluid. And
it must be mildly moist! NEVER use strong fluids and/or erasers. Before cleaning ALWAYS
remove the power cord from its wall socket, by its plug not by its cord.
The optimum operating temperature (35° - 40° C) is reached after approx. 60 minutes of
continuous play. Then it will be possible to start enjoying the superb van Medevoort audio qualities
of this class ‘A’ amplifier.
We strongly recommend that you use a high quality Interconnect cable. E.g. the renowned van
Medevoort Silver Cable. Also for the power cords.
