Cedrus Voice Key SV-1
Acquire Vocal Reaction Times with Peace of Mind
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 such as:
Built-in timer: 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.
Advanced Technology: SV-1 is powered by an 18 MHz microprocessor and is a 100% digital device. It uses Cedrus' XID technology which is fully documented.
Controls Lock: 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 and a one year full warranty which covers all parts and labor. Yes, a battery is included.
