Infinity Room loop
The Infinity has been designed for quick and easy set up of small, medium and large rooms or
auditoria, for lecture or recreational purposes, to assist both hearing aid wearers and others
where public address is required.
The Infinity series are Induction Loop Amplifiers which can be configured with a variety of
Handheld, Boundary and Radio Microphones, together with Radio Wireless Speakers if required.
Infinityloop is available as a fully portable system (pictured above) or as a fixed unit.
Any number of additional Radio Speakers may be added for larger rooms without degradation
of sound quality.
Infinityloop has a variety of sound inputs to enable Televisions, Videos, DVD, Hi-Fi/Multimedia to
be annexed, whilst an audio output (phono) provides connectivity to Tape Decks and secondary
sound amplifiers.
