Setting up the VS5012

WARNING!

To avoid electrical shock or any other damage, make sure that the VS5012 
and all other devices are switched off before you start connecting them to the 
amplifi er!

Power Connections/Mains

Before connecting to a grounded power outlet, 
make sure the power switches are in the off position 
(facing down). The VS5012 is set up for 230 V of line 
voltage. You should start up like this: Set the power 
switch to position „On“ and wait for about 40-60 
seconds. During this time, all tubes and electric cir-
cuits will warm up. After that you can activate the 
power amp by switching the standby switch to the 
“On“ position. Once the amplifi er is activated, you 
can get started!

Connecting an electric guitar

The input jacks on the left side of the frontpanel 
receive your electric guitar signal by means of a 
shielded guitar cord with 1/4” mono style plug. 
Make sure the master volume of the amplifi er is set 
to the lowest position to avoid disturbing noise while 
connecting.

Speaker protection

The VS5012 has a built-in 12” speaker. It can be
damaged by heavy feedbacks of the connected 
instruments. You should always keep a suffi cient 
distance to the amplifi er to avoid such feedbacks. This 
will extend the life of the speaker and the power amp.

Travelling Abroad

If travelling to countries outside the EU, always check 
their local voltage before operating the VS5012. 
Mismatched voltages can and most likely will destroy 
your amplifi er. Should you encounter voltages and 
frequencies other than those indicated, a transformer 
must be used between the power socket and the 
VS5012. This transformer must be able to transform the 
voltage and frequency to one of the indicated settings.

Main Fuse

The main fuse is situated inside a rotating pin next to 
the power input. This sliding fuse holder also hides a 
spare fuse. For 230 V, the fuse must be a 1,25A slow 
blow. It is crucially important to use the specifi ed fuse 
values only.

Tube Maintenance

Power tubes last 1 to 3 years, depending on care, 
volume and frequency of use of the amplifi er. If you 
use your amp only once a month, then the tubes 
will last longer. Get it? We have heard tubes that 
were over 10 years old, but it was not a good thing. 
Tubes age very slowly, slow enough for the artist to 
get used to the changing tone. To keep things fresh, 
we recommend retubing, cleaning and biasing once 
a year if the amp is used frequently.
