• acoustic echo cancellation
• noise dependent volume control
• acoustic exposure monitoring and control
• music EQ profiles (bass, treble, rock, classic)

VoIP amplifier for contact centre

SonoKlara® VoIP amplifier protects contact centre agents from a wide range of acoustic incidents and significantly reduces risk of injuries from acoustic shock and noise-induced hearing loss through the headset. It also offers speech enhancement, noise dose monitoring and is fully compliant with EU Directive 2003/10/EC.
