 Product Description: The single-channel IRR-15 has the same basic features as the IRR-23, but with only one channel, and is for those on a budget. Later, you can add a second receiver on another channel and get the same results as the IRR-23. Product Specifications:| IRR-15 1-channel receiver | | | Sub-carrier frequencies | 2.06MHz or 2.56MHz | | Type | super heterodyne – crystal controlled | | Modulation | FM | | Signal-to-Noise | >83dB | | Image rejection | >40dB | | Reception sensitivity | >25dBµV | | Reception selectivity | ±40kHz | | Audio output adjustment | line:+2dB max (10k ohm load), mic:-26dBm (600 ohm load) | | Audio output impedance | line:<1k ohms | | Audio input impedance | line:<1k ohms | | Power requirement | 12VAC @ 300 mA | | Size | 3.94" W x 6.34" D x 1.57" H (100 x 161 x 44mm) | | Weight | 18.7oz (530g) | REGULAR PRICE: $250.00 Our Low Sale Price: $225.00  Product Description: Now you can use an unlimited number of systems in the same building and not worry about frequency interference! The Azden "Red" Series of infrared wireless microphones is the solution for classrooms, auditoriums, churches, conference/meeting rooms, and health clubs, and where ever security is an issue.The two-channel IRR-30 receiver allows the use of two mics at the same time. Each channel has its own frequency and every IRR-30 uses the same two frequencies. The receiver's built-in sensor array allows complete freedom of movement in a 1600-sq.ft. room. For larger rooms, up to three wall/ceiling mountable external sensors (IRD-30 or IRD-60) increase the working distance. If the receiver is mounted in a secured cabinet the third sensor input disables and replaces the receiver's internal sensor.

It allows you to use and control the volume of 2 wireless microphones simultaneously, either for "team-teaching, or to use the handheld microphone for student pass-around. The receiver also has 2 stereo auxiliary inputs so that other line-level devices (CD players, MP3 players, VCRs, etc.) can be attached and played through the system. The teacher can also send the audio to a recorder or video camera, using the line-level output jack. For bigger rooms or odd-shaped rooms up to 3 additional external sensors can be attached. With all 4 of the ceiling speakers attached to the IRR-30P, sound is spread equally throughout the room, allowing all students to hear equally.
