If you need four or more specialized amplification channels for multi-channel recording, the MMRS system offers a unique solution. You specify your needs, well design the circuits, and the final package will be smaller, less expensive, and easier to use than obtaining the equivalent performance from general purpose amplifiers.An MMRS system generally consists of a rack-mountable power supply (RP-2), 4-13 modular card-mounted amplifiers, and an optional multi-channel hybrid IC probe. The high-impedance DC probe is specially designed for high impedance recording from moving animals. It consists of 25 DC coupled F.E.T. inputs. Less than 1 oz. weight and cubic inch size plus ultra-flexible woven ribbon cable and miniature connector make this ideal for use with floating microelectrodes in freely moving or partially restrained animals.The modular card amplifiers can be designed for either second stage amplification of the signals from the probe or for stand-alone use, having an input impedance of 1 megohm. Generally, a probe stage is not necessary when source impedances (electrodes) are under 50 kilohms and leads can be kept reasonably short and shielded. The MMRS cards can be designed for single-ended, differential, AC or DC amplification and any combination in one system. While panel space is limited, switches and controls can be incorporated to allow a few user specified options of filtering, gain, balance, etc One slot of the power supply cage can be fitted with a scanning switch which can be used to select lines from the probe stage into the first card amplifier. This is very useful for scanning through multi-channel arrays to inspect input signals without constantly reconnecting to individual amplifier outputs.
