HUMAN EXPOSURE COMPLIANCE STATEMENT..............................................16 2 1. General Description SoundCast is a complete point-to-point and point-to-multipoint wireless audio solution. SoundCast digitizes a 2-channel stereo input signal, sends it across a robust radio frequency link, and then converts it back to a stereo analog signal for use at a remote location. SoundCast is ideal for home theater rear speakers, headphones, public address systems, and outdoor speakers. SoundCast wireless audio product family has two members. SoundCast G2 has 25 meter indoor range while SoundCast G2-ER has 50 meter indoor range. Figure 1 and 2 are the system block diagrams for SoundCast G2 and SoundCast G2-ER modules. Figure 1, SoundCast G2 system block diagram 3 Figure 2, SoundCast G2-ER system block diagram 4 2. Features v Stereo Analog In/Analog Out, Digital In/Digital Out; v 92.4 dB SNR, 0.065% THD+N; v Digital volume control; v Auto Mute; v Digital Noise Gate; v 2.4 GHz wireless link, 1.536 Mbps data rate; v 25 m indoor range for the SoundCast G2 module and 45 m indoor range for the SoundCast G2-ER module; v Each transmitter supports two receivers with stereo output from both receivers; v Up to 6 transmitters in one area; v Low latency (15 ms – 64 ms selectable); v Low power consumption; v Best in Class quality of service (QoS); v Duplex utility control channel; v Modules come with antenna soldered on for easy integration 5 3. Electrical Specifications 3.1 Operating Conditions – SoundCast G2 Transmitter Note: All Min/Max characteristics and specifications are guaranteed over the Specified operating conditions. Typical performance characteristics and specifications are derived from measurements taken at typical supply voltages and TA=25oC. 3.2 Absolute Maximum Ratings – SoundCast G2 Transmitter 6 3.3 Operating Conditions – SoundCast G2 Receiver 3.4 Absolute Maximum Ratings – SoundCast G2 Receiver 7 3.5 Operating Conditions – SoundCast G2-ER Transmitter 3.6 Absolute Maximum Ratings – SoundCast G2-ER Transmitter 8 3.7 Operating Conditions – SoundCast G2-ER Receiver 9 3.8 Absolute Maximum Ratings – SoundCast G2-ER Receiver 10 4. Audio Characteristics This table describes the audio characteristics of SoundCast (5.0V supply applied to the DAC on the SoundCast G2 Receiver). Note: 1. All measurements are for 5 bit HFADPCM encoding. 2. Relative to Full Scale Output at RX Line Out, Left Channel. 3. RX Line Out into a 10 k? load. 11 5. RF Characteristics The SoundCast RF algorithm is described below paying special attention to include information pertinent to FCC and ETSI regulations. The SoundCast software operates by selecting a palette (or group) of 15 random channels out of the total 38 to hop on. For the 15-channel palette, any channels with poor transmission rates are replaced with better channels from the remaining 23 unused channels. The hopping pattern from channel to channel is a random pattern. The following table describes some important aspects of the channel-hopping algorithm: 12 13 5.1 RF Characteristics - SoundCast G2 Transmitter and Receiver 5.2 RF Characteristics - SoundCast G2-ER Transmitter and Receiver 14 6.
