The compact amplifier with slide switches –
VGO
In addition to the devices with electronic setting, Kathrein offers yet another highly innovative compact amplifier platform. This particularly economical series requires no equaliser cards
or attenuation pads. All adjustments can be easily carried out using slide switches.
Simple, yet effective
The required attenuation and slope values are set with a combination of several slide switches. The advantages are obvious. Besides saving
Replacement of the device, for example, is thus much easier.
When slide switches are shifted, a virtually uninter- rupted signal flow is guaranteed – multimedia services remain undisturbed.
Maximum reliability
The implemented slide switches fulfil the highest demands regarding reliability and endurance. Dual
