KONANlabs KSP-IO12
INSTRUCTION MANUAL

Thanks for purchasing our products. Please read the Instruction Manual carefully before you
use the network audio processor.
Instruction
Network audio processor is a closed-loop feedback control system, which can make the PLL
output keep the fixed phase relationship with a reference signal. The processor include
discriminator, charge amplifier, low pass filter, voltage control oscillator and output converter,
which can completely avoid network duplex echo.
Network audio processor equipped with USB terminal, efficient implementation reduces
network inherent noise, inhibition of multi-party conference echo, and this product is widely
used in local conference and teleconference to eliminate feedback and echo.
Features
1. Echo cancellation, completely eliminate echo, and transmit the local signal at the same
time, support fully duplex at any time.
2. Acoustic feedback howling suppression
3. The unique dynamic adaptive noise filter can filter out background noise but does not
affect the speaker's voice; thereby improving the signal to noise ratio, improve the sound
quality.
4. The most advanced signal processing. It can be used for network conference, audio and
video teleconference. Fully adaptive conference equipments, without the system
debugging.
5. Powered by computer USB interface, no need other extra power.
