DAM50 - Basic Amplifier (optional #5447 electrode
adapter not include)
DAM60 -
Basic feature plus Current Generator
|
|
|
|
|
DAM50 and DAM60 offer AC/DC
amplification, high and low bandwidth filtering with the
same low-noise "front-end" design, for
extracellular recording, EMG, EKG, etc. In addition, DAM
60 includes a linear electrode current generator for
tissue marking and electrode impedance measurement. Both
preamplifiers come equipped with two unserviced modular
cables designed to be wired to the user's input device. An
optional Electrode Adapter (#5447) accommodates input
devices with 2 mm plugs. When very low noise is required,
the input cables can be replaced with optional shielded
cables (#3517). DAM60 also comes equipped with two cables
which are male plug to BNC and can be used to connect the
output to a recording device. |

DAM70 - Basic plus
Current Generator
with Gated Stimulus Artifact Suppression (SAS)
DAM80 - With
low-noise headstage DAM80P
(Metal microelectrode adapter #5469 included.)
DAM 70
offers AC/DC amplification, high and low bandwidth
filtering with the same low-noise "front-end"
design, for extracellular recording, EMG, EKG, etc. It
also includes a linear electrode current generator for
tissue marking and electrode impedance measurement and
features gated stimulus artefact suppression. Optional
microelectrode holder MEH8 and cable #3517 are required
for this feature. DAM70 comes equipped with two
unserviced modular cables designed to be wired to the
user's input device. An optional Electrode Adapter
(#5447) accommodates input devices with 2 mm plugs.
DAM70 also comes equipped with three male plug to BNC
cables used to connect the output to a recording device.
DAM80, an AC amplifier only, features a very low noise
headstage probe which can be mounted in
micromanipulators for up-close cortical recording, for
extracellular recording from high impedance glass or
metal microelectrodes. Also provides a gated current for
tissue marking. Microelectrode holder MEH3SB is
recommended.
