D440 2 or 4 Channel Isolated Amplifier

D440 Isolated Amplifier is a low noise solution for human EMG studies, specifically those related to nerve excitability.

Low noise performance is significantly enhanced through the use of a Driven Right Leg (DRL) circuit which reduces Common-mode interference.

The D440 features an amplification range of x100 to x20k. The gain, filter and mode settings for individual channels are adjusted using our own "virtual front panel" software or other software via a COM interface.

The D440 is available in two versions - D440-2 has two channels and the D440-4 has four channels.  Each channel features a pair of 1.5mm touch proof sockets or a 5-pin DIN connector.  Each amplifier is supplied with a signal output cable (D connector to multiple BNC) and electrode connection cables (1.2m long with 3x 1.5mm DIN42802 connectors for electrode connection and 5-pin DIN for amplifier connection).

Major Features Include:

- Portable, standalone design

- Extremely low noise.

- Rapid recovery from stimulus artefacts

- AC and DC operating modes

- Analogue signal output

- Computer controlled

- Designed for human research applications, including nerve excitability testing
