The IR-CS system consist of:
IRR-30Px1,IRH-15cx1,IRN-10x1,IRD-60x1,Celing x4
IRR-30P
Technical Specs:
The heart of the
Azden infrared system is the IRR-30P powered, dual-channel
receiver. 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.

IRH-15c
Technical
Specs:
The perfect handheld "pass-around" microphone for student
participation, this dual channel microphone/transmitter, operates
on the channel that the teacher is not using. It is powered by two
"AA" batteries (Alkaline or rechargeable (1HR-3U only)) and is
compatible with all Azden infrared models.
Sub-carrier frequencies: 2.06MHz & 2.56MHz switchable
Modulation: FM
Microphone element type: Uni-directional dynamic
Frequency Response: 50-8kHz ±3dB
Battery type: 2-“AA” Alkaline (1.5V x 2 ) or
2-1HR-3U “AA” rechargeable Ni-MH (1.2V x 2 )
Battery life: > 6 hours w/alkaline batteries
Size: 9.65" x approx.1.375" (245 x approx. 35mm)
Weight: 9.1oz (258g) w/alkaline batteries)
IRN-10
Technical
Specs:
A lightweight, chest worn, microphone/transmitter, the IRN-10 comes
with an adjustable lanyard. It is both a microphone and infrared
transmitter which wirelessly "links" the teacher to the
IRr-15/IRR-30/IRR-30P receiver. It has a specially designed
internal microphone array which provides great sound pick-up. With
two switchable channels, a teacher can go from classroom to
classroom with the same microphone! With just two "AA" batteries
(Alkaline or rechargeable (1HR-3U only)) the microphone can be used
the entire school day without re-charging or changing
batteries.
Sub-carrier frequencies: 2.06MHz & 2.56MHz switchable
Modulation: FM
Microphone element type: Uni-directional electret x 2
Frequency response: 50-9kHz ±3dB
Ext Mic input imped.: 2.2k Ω Ext Mic input jack: 3.5mm
Ext. Mic Voltage/Current: 3.5VDC @ 1mA
Mic gain adjustment: +6dB to approx. –10dB
Battery type: 2-"AA" Alkaline (1.5V x 2) or
2-1HR-3U "AA" rechargeable Ni-MH (1.2V x 2)
Battery life: > 8hours w/alkaline batteries
Size: 3.15" H x 2.75" W x 1.06" D (80 x 70 x 27mm)
Weight: 4.3oz (120g) -w/alkaline batteries
IRD-60
Technical Specs:
The IRD-60 is an externally mounted infrared
sensor that is used with the IRR-15, IRR-30, IRR-30P receivers and
the APS 25 speaker system that has the APS-IRII installed. The
sensor is fitted with an "F" connector and comes with a ceiling
mounting bracket.
