The Clear-Com Encore intercom system delivers superb audio performance while offering a streamlined, user-intuitive design. All components are built to handle the roughest use in fast-paced, high-intensity applications. Even under the most challenging conditions, the noise attenuating headsets and noise canceling microphones, combined with anti-sidetone circuitry, minimize acoustic noise and feedback to provide superior sound quality. The Clear-Com MS-702 is a one-rackspace, two-channel main station with a regulated 1.2-amp fail-safe power supply, individual channel short-circuit protection and a versatile intercom monitoring system. It supports two intercom channels with up to 40 beltpacks or 10 speaker stations. It offers excellent speech intelligibility in both high- and low-noise environments.The Clear-Com MS-702 can monitor intercom activity on one or both channels with individual listen-level controls. Monitoring intercom activity is possible through a headset or the internal loudspeaker. The high-sensitivity internal speaker provides intelligible communication in the most active production environments. The Clear-Com MS-702 contains mic preamps with limiters, and speech-shaping circuits for enhanced intelligibility. An individual electronic momentary/latching talk button is provided for each channel. These buttons light dimly when latched – blue-color LED while in stand-by and amber-color LED when latched. The channels may be accessed separately or simultaneously without tying them together. An optional gooseneck mic is available.Main Features:Supports up to 40 beltpacks or 10 speaker stations on two channels and 12 headsetsSeparate short-circuit protection for each channelDual-action electronic momentary/latching talk buttonsProgram feed to both channels, with selectable Program Interrupt (IFB)Call signal buttons for each channelGlobal Remote Mic KillAnnounce output with relayMicrophone limitingVolume controls for each channelVisual and audible Tone Alert signalingChannels A & B Link switchBuilt-in speakerOptional gooseneck micExternal switchable line termination on each channelUniversal voltage power supply for 100-240 VAC operationSpecifications:Station Capacity: Up to 55 RS-701 beltpacks or 10 speaker stations or 12 headset stations distributed over both channelsPanel Microphone Input Input Type: Electret Input Impedance: >=2K Mic Limiter Threshold: 0dBu 3dB Mic Limiter Range: >= 20dBHeadset Microphone Input Input Type: Dynamic Input Impedance: >= 1K Mic Limiter Threshold: 0dBu 3dB Mic Limiter Range: >= 15dBProgram Line Input Maximum Level before Clipping: >= 20dBu Input Impedance: >= 5KHeadset Output Load Impedance: >= 8 Output Impedance: = 17dBuSpeaker Output Load Impedance: >= 4 Max Output Level before 1% Distortion: 20dBu 2dBuPartyline Output O Noise: < -74dBu Output Impedance: >10KPartyline Input Crosstalk: < -60dB Max level before Clipping: >= 12dBu Sidetone Null Capability: > 25dBStage Announce/Balanced Line Out Type: Balanced Output Impedance: >= 200 Load Impedance: >= 600IFB/Hot Mic Type : Unbalanced Output Impedance: 180 Load Impedance: >= 600Frequency Response Panel Mic – Partyline: 600 – 10kHz 3dB Headset Mic – Partyline: 200 – 12kHz 3dB Headset Mic – Line Out: 200 – 12kHz 3dB Program Input – Partyline: 100 17kHz 3dB Program Input – Headset Out: 200 – 10kHz 3dB Program Input – Speaker Out: 300 – 10kHz 3dB Partyline – Headset Out: 200 – 10kHz 3dB Partyline – Speaker Out: 300 – 10kHz 3dBMax Distortion Panel Mic – Partyline:
