• To achieve an improvement in SNR up from a Bluetooth Microphone system<br />
would be to use a fixed gain wireless system<br />
• Examples include:<br />
– <strong>Phonak</strong>‟s 2 nd Generation systems such as Campus, SmartLink SX,<br />
ZoomLink, EasyLink (silver casing)<br />
– Oticon Amigo<br />
– Comfort Audio Digisystem<br />
• These are all examples of fixed gain systems and achieve similar results<br />
• Most incorporate <strong>directional</strong> <strong>microphone</strong>s on the transmitters and therefore<br />
can achieve higher SNR‟s than Bluetooth <strong>microphone</strong>s<br />
• Additional benefits include greater operating ranges and longer battery life<br />
• However, cost is significantly higher
