Benchmaster
          8 - Versatile 2 Channel Filter Amplifier



          The BenchMaster
          8 dual channel filter with gain, is considered by many to be
          the `standard classic' benchtop laboratory analogue filter. Now
          in its 6t" generation, it has been in continuous production
          since 1975, with 1000's in use worldwide.



          •
          2 Independent Channels

          • Differential/Single ended input

          • Switchable High/Low pass

          • `Pulse' and `Flat' Modes

          • 0.01 Hz - 99.9 kHz filter range

          • Range of filter types

          • Input gain to x 500 (+54 dB)

          • IEPE 4 mA transducer supply

          • 6 models, 6 filter responses 

          • 4 stage signal level indication

          • 3 digit frequency setting 

          • Optional DC powered versions

          • Highpass / Lowpass / Bandpass / Bandstop / Notch 



          The BenchMaster 8 is available in a range of different filter
          types: Butterworth, Bessel (4 and 8 pole), general purpose linear
          phase, and anti-aliasing responses. The two independent channels
          can each be switched between highpass and lowpass, or combined
          in series or parallel to give; two channels of lowpass, two channels
          of highpass, one lowpass/one highpass, series connection to give
          bandpass, and parallel connection for bandstop/notch filtering.



          The BenchMaster 8 has easy to use clear front panel controls,
          with BNC input and output. The inputs can be AC or DC coupled,
          single ended or differential. Up to +54dB(x500) of gain can be
          applied, in 9 steps, to the input before filtering, with 4 stage
          signal level indication. An IEPE 4 mA current source is available
          for transducer power, with indication of correct connection.



          The basic filter response has 3 'modifier' settings: a minimum
          overshoot `pulse' mode for impulsive signals; `flat' which provides
          a flattened response to cut-off; and a`Butterworth' type response
          with -3 dB at cut off frequency. Using the 'flat' modifier true
          16 pole Bessel and Butterworth filters can be set, maintaining
          -3dB at cutoff .



          Optional 10 - 30 Volt DC power input allows use for portable
          and vehicle applications. The compact 1 U metal case is designed
          for both bench top use and rack mounting.

          All together, no other laboratory filter offers so many features
          for the price or size.
