Specifications
Safety
The D360R-4 has been designed to meet all of the electrical requirements of IEC 60601-1, ensuring
safety in a human research environment. This includes but is not limited to:

Input circuit is fully electrically isolated.

Creepage and clearance meets or exceeds the minimum requirements.

All inputs are single fault condition safe.
Power requirements
Mains requirements: 120/240AVC (Switch selected) 50/60 Hz
Headstage
The headstage is a small remote pre-amplifier to which the operator connects the electrodes from
the subject to the amplifier. The amplifier head stage is small enough to be attached to a subject to
permit partial mobility should this be required. The headstage is connected to the main amplifier
using a 2m multi-way cable with plastic Lemo Redel connectors at both ends. The cable is
symmetrical allowing it to be connected either way round.

Differential Channel Input (+ve [ref] –ve[act]) for all channels (Red & Blue 1.5mm DIN42802
touch-proof sockets); inputs are connected to COM when a channel is disabled (Off).

1GΩ Input impedance

Independent channel enable

Single COM reference input (1.5mm touch-proof DIN42802 sockets).
Deblock
The deblock is a means to remove excessive DC from the low pass series capacitors which in certain
situations could block the signal. The de-block can be applied in using the PC Application, a button
press on the headstage or using a precise TTL sync voltage connected to an input BNC on the
device’s rear panel.
The deblock parameters are applied to all channels
TTL BNC Input (2 modes)

Timed 0.1ms – 10ms (0.1 steps) – Triggered on rising edge of TTL BNC input.

Manual – Deblock active for the time TTL BNC input is held high.
Deblock button on headstage, applied whilst button depressed.
Deblock can be applied using the Client Software or API.
Analogue Channels

Maximum Channels : 4

CMRR : ≥90dB
The following channel parameters can be independently controlled:

Gain : x100 – x3,000,000 (10mV/V – 0.33µV/V)
80 gains from x100 to x3,000,000
