External Pre-amplifiers
-
Although all Spectrum A/D cards have a very powerful input section with a highly configurable input amplifier and a variety of input ranges it is sometimes necessary to have additional external amplifiers if the signal to acquire has an extremely low level. Spectrum offers a range of perfectly matching external amplifiers to cover such cases. These powerful amplifiers have been rated using the Spectrum cards and offer best performance together with high amplification rates.The amplifiers are simply connected between the signal source and the Spectrum A/D card input and can be manually switched between different settings using small lever keys. All amplifiers allow the offset compensation by using an adjustable screw.

RX Pre-Amplifier System
RAM-34
-
The RAM-34 is a complete pre-amplifier system designed primarily for the low bands 160M thru 40M. It has inputs for four receive antennas and internal 3-pole bandpass filters for 160M, 80M and 40M. In addition to the pre-amplifier, it has a step attenuator that togetherwith the amplifier stage provides gains from -20 dB to +20 dB in 5 dB steps. This allows equalizing the signal levels between the antenna inputs. Gain settings are memorized for each antenna on each band. Different types of receive antennas have different signal levels and the gain memories eliminate the need to adjust the receiver or pre-amplifier when switching between the antennas.
