Check the listing for details. Studio Technologies MODEL-372A Intercom Beltpack with Dante. Condition: New. Listed at 465.00 USD. Combining a single channel of talk and two channels of listen capabilities, Studio Technologies' Model 372A Intercom Beltpack is a highly compact user-worn device that starts off with the features you'll find onboard traditional analog party-line (PL) intercom user devices, then adds a range of newer capabilities, as well as the advanced performance and versatility that Dante® audio-over-Ethernet brings. Over a standard IP network, multiple Model 372A units and other compatible Studio Technologies' beltpack devices can be used to create party-line intercom applications with assistance from an external Dante-enabled audio matrix such as the Studio Technologies' Model 5422 Dante Intercom Audio Engine (sold separately). Alternately and additionally, these can be used "point-to-point" or interfaced with Dante-compatible matrix intercom systems too.Key FeaturesDante audio-over-Ethernet technologyOne talk and two listen channelsSupports dynamic and electret microphones5-pin female XLR headset connector3.5mm 4-conductor TRRS headset connectorCall receive and display functionExcellent audio qualityUses STcontroller software app for configurationAES67 and Dante Domain Manager™ (DDM) supportPower-over-Ethernet (PoE) poweredSpecificationsGeneral:Audio Channels: 1 talk, 2 listenMicrophone Input:Compatibility: dynamic or electret (low-voltage DC-powered) microphonesType: unbalancedElectret Microphone Power: 3.3 volts DC via 2.00 k resistor, selectable on/offImpedance: 1 k ohms, nominal, microphone power off; 690 ohms, nominal, microphone power onGain: 24, 30, 36, 42, or 48 dB, selectable, ref. –60 dBu input to Dante output (–20 dBFS nominal)Frequency Response: 40 Hz to 20 kHz, –3 dBDistortion (THD+N):Dynamic Range: 91 dB of dynamic rangeConnectors:Headset A: 5-pin female XLRHeadset B: 4-conductor (TRRS) 3.5 mm jack, per Japanese standard JEITA/EIAJ RC-5325AEthernet: Neutrik NE8FBH etherCON RJ45 receptacleUSB: type A receptacle (located inside Model 372A's enclosure and used only for application firmware updates)Configuration: requires Studio Technologies' STcontroller software application, version 2.01.00 and laterPower Source:Power-over-Ethernet (PoE): class 1 (very low power, ≤ 3.84 watts) per IEEE® 802.3afNetwork Audio Technology:Type: Dante audio-over-EthernetAES67-2013 Support: yesDante Domain Manager (DDM) Support: yesBit Depth: up to 24Sample Rate: 48 kHzNumber of Transmitter (Output) Channels: 1Number of Receiver (Input) Channels: 2Dante Audio Flows: 4; 2 transmitter, 2 receiverNetwork Interface:Type: 100BASE-TX, twisted-pair Ethernet, Power-over-Ethernet (PoE) supportedData Rate: 100 Mb/s (10 Mb/s and 1000 Mb/s "GigE" Ethernet not supported)Compatibility – Headset A: single- or dual-ear broadcast-style with dynamic or electret (low-voltage DC-powered) microphone: pin 1 mic common; pin 2 mic; pin 3 phones common; pin 4 phones left; pin 5 phones rightCompatibility – Headset B: CTIA™/AHJ configuration (typically uses electret powered mic): tip phones left; ring 1 phones right; ring 2 common; sleeve micNote: Specifications and further information can be found within the items located under the "Documentation" tab above.
