Utilizing packet audio technology, the NX-300W ensures real-time transmission, allowing for flawless audio delivery without the need for additional wiring. This feature makes it an ideal solution for large-scale audio systems where maintaining consistent quality is essential, such as in broadcasting, industrial settings, and public address applications.\u003c\/p\u003e  \u003cp\u003eWith the ability to transmit audio and control signals simultaneously, the NX-300W is perfect for environments where both high-quality sound and control functionality are crucial. It supports up to 8 different priority levels for broadcasting audio files, enabling flexibility in managing audio content across multiple locations. The device’s dual-channel full-duplex capability allows for bi-directional transmission of dual mono signals, making it a versatile addition to any professional audio network. Whether used for system intercoms, announcements, or background music, the NX-300W provides the reliability and scalability needed for demanding applications.\u003c\/p\u003e  \u003cp\u003eAdditionally, the NX-300W offers exceptional scalability. Up to 500 NX-300 units can be interconnected via a single LAN, allowing for expansive audio networks. Each audio signal can be streamed to a maximum of 16 NX-300Ws using unicast transmission or 64 NX-300Ws using multicast transmission, ensuring that audio content can be delivered simultaneously across a vast number of devices. This makes the NX-300W a powerful choice for enterprises that need to maintain synchronized audio throughout a large facility or across multiple locations.\u003c\/p\u003e  \u003ch3\u003eKey Features\u003c\/h3\u003e \u003cul\u003e   \u003cli\u003e \u003cstrong\u003eAudio Input:\u003c\/strong\u003e 2 channels, balanced (transformer isolated)\/unbalanced changeable, volume adjustable.\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eAudio Output:\u003c\/strong\u003e 2 channels, balanced (transformer isolated), 600 Ω or less.\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eAudio Format:\u003c\/strong\u003e WAV file support, sub-band ADPCM encoding.\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eControl Inputs\/Outputs:\u003c\/strong\u003e 8 control input channels, open collector outputs, relay outputs.\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eNetwork Connectivity:\u003c\/strong\u003e 10BASE-T\/100BASE-TX, supporting TCP, UDP, HTTP, RTP, and more.\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eVoice Sampling:\u003c\/strong\u003e 8 kHz, 16 kHz, 32 kHz, and 48 kHz (software-controllable).\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eStorage:\u003c\/strong\u003e Supports up to 32 GB SD\/SDHC card for log storage (max. 10,000 entries).\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eMounting Options:\u003c\/strong\u003e Rack, desk, or surface mountable, with optional rack or wall mounting brackets.\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e -10°C to +50°C (14°F to 122°F).\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eScalability:\u003c\/strong\u003e Up to 500 units can be connected over LAN, with up to 1,000 links.\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eBroadcast Capability:\u003c\/strong\u003e Up to 16 NX-300W devices for unicast and 64 devices for multicast transmissions from one audio input.\u003c\/li\u003e \u003c\/ul\u003e  \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e \u003cp\u003e\u003cstrong\u003ePower Source\u003c\/strong\u003e: Supplied from an external 24 V DC (21.6 - 26.4 V) power supply or AC adapter AD-246 (option) or equivalent.\u003cbr\u003e \u003cstrong\u003eCurrent Consumption\u003c\/strong\u003e: 10 W (AC operation), 310 mA (DC operation).\u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eAudio Input\u003c\/strong\u003e: 2 channels, balanced (transformer isolated)\/unbalanced changeable, 2 kΩ, LINE\/MIC changeable, volume adjustable.\u003cbr\u003e \u003cstrong\u003eRated Input\u003c\/strong\u003e: -20 dB (*2) (LINE)\/-60 dB (*2) (MIC).\u003cbr\u003e \u003cstrong\u003ePAD Function\u003c\/strong\u003e: -16 dB (*2), removable terminal block (6 pins).\u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eAudio Output\u003c\/strong\u003e: 2 channels, balanced (transformer isolated), 600 Ω or less.\u003cbr\u003e \u003cstrong\u003eRated Output\u003c\/strong\u003e: 0 dB (*2) (unbalanced input)\/-2 dB (*2) (balanced input), removable terminal block (6 pins).\u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eFrequency Response\u003c\/strong\u003e: 50 Hz - 18 kHz (48 kHz sampling frequency, PCM, 0 to -6 dB deviation referred to 1 kHz).\u003cbr\u003e \u003cstrong\u003eDistortion\u003c\/strong\u003e: 0.2 % or less (1 kHz, LINE signal level, 48 kHz sampling frequency, PCM, BPF).\u003cbr\u003e \u003cstrong\u003eSignal to Noise Ratio\u003c\/strong\u003e: 73 dB or more (LINE signal level, at rated output).\u003cbr\u003e \u003cstrong\u003eSeparation\u003c\/strong\u003e: 70 dB or more (1 kHz, LINE signal level, BPF).\u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eAudio Format\u003c\/strong\u003e: WAV file.\u003cbr\u003e \u003cstrong\u003eNumber of Storable Audio Files\u003c\/strong\u003e: Max. 8.\u003cbr\u003e \u003cstrong\u003eStorable Time of Audio File\u003c\/strong\u003e: Max. 2 min. per audio file (16 kHz sampling frequency, sub-band ADPCM, monaural operation).\u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eControl Input\u003c\/strong\u003e: 8 channels, no-voltage make contact input, open voltage: 24 V DC, short-circuit current: 2 mA or less, removable terminal block (9 pins).
