 Measure vocal reaction time precisely
SV-1
is a device designed specifically for experiments requiring a vocal
response. SV-1 monitors the participant's voice level at all times, and
when the level rises above a user-specified threshold, it reports this
to the computer. The first such device to be developed for over a
decade, SV-1 packs some advanced features.

For example, at the onset of a trial, the computer can reset the
timer in SV-1. When SV-1 detects a voice key, it informs the
computer and reports the participant's reaction time with a
guaranteed accuracy of 1 millisecond.
SV-1 is powered by an 18 MHz microprocessor and is a 100% digital
device. It uses Cedrus' XID technology which is fully documented.
Thanks to its digital design, after adjusting the dials to the
correct levels you can use the computer to "lock" them. This makes
them ineffective and prevents accidental tampering.

Serial and Parallel Ports
SV-1 offers both a serial and a parallel port for maximum
connectivity. USB support can be added via an inexpensive USB-serial
port adaptor.
-
Flexible Accessory Connector
The built-in Accessory Connector provides six lines of I/O
(input/output). Each line can individually be configured as either
input or output.
SV-1 comes with a microphone headset (see picture above) and a one
year full warranty which covers all parts and labor. Yes, a battery is
included.
