The VAMP four is extremely easy to hook up and use.
1./Apply power and confirm unit is powered up and active by acknowledging
the mains indicator is on.
Allow approximately one minute minimum for the valves to warm up
and begin amplifying the sound. Connect output to destination device.
2./Plug in sound source ( bass,guitar,keyboard etc. ) and adjust pad/gain con-
trol to achieve a reasonable level on the LEDs.
The green LED in particular should be responsive to sounds.To get a
more coloured sound gradually increase the pad/gain control.
When the yellow LED begins to flash , this indicates that the drive
level is in the non-linear or ‘hot’ region of the valves amplifying zone.If you
require more colour simply turn up the pad/gain control.
Use the ‘deep’ or ‘air’ passive EQ switches to sweeten the signal to taste.
3./Adjust output level control for an appropriate reading on your computer or
tape machine etc.
The VAMP four has plenty of output drive to easily interface with
virtually all destination devices. For a full bodied noise-free signal it is
recommended to use balanced cables where possible .These can be either
XLR or TRS phono.
There are two outputs for each of the four valve channels.Each output
can be fed to completely individual units (soundcard and monitor mixer for
example).
If there is a requirement for even more colour or distortion that a single
channel can deliver it is easy and recommended to connect the output of one
channel into the input of another channel using a short phono to phono patch
lead.
With this configuration , the signal chain has four controls to control
colour and texture of the sound as well as the four EQ switches.
