    For regular classroom use, many teachers prefer to use the Quantum II for infrared wireless transmission. This system uses the same Sapphire Pendant transmitter that is used with the infrared classroom sound-field systems. This unit will cover up to 1800 square feet and must be used indoors. This amplifier can be wall mounted, installed on a tripod stand or free standing on a shelf or cabinet.
