About the Yamaha NAI48-ES
The Yamaha NAI48-ES is a digital audio network interface that uses the EtherSound protocol to carry up to 48 channels of digital audio in each direction over a single Cat-5 Ethernet cable, across distances of up to 100 metres with appropriate high-performance cables. Forty-eight AES/EBU inputs and 48 AES/EBU outputs are provided via 25-pin D-sub connectors, allowing direct connection to a wide range of digital front-end devices including the Yamaha AD8HR 8-channel remote head amplifier. EtherSound networking handles transfer of audio channels alongside remote control signals for compatible devices, and standard Ethernet hubs and routers can be used within the signal path. EtherSound capability can be added to compatible Yamaha digital mixing consoles via AuviTran AVY16-ES cards installed in Mini-YGDAI slots.
Yamaha NAI48-ES — buyer FAQs
What is the Yamaha NAI48-ES and what does it do?
The Yamaha NAI48-ES is a digital audio network interface that uses the EtherSound protocol to carry up to 48 channels of 24-bit 48kHz audio in each direction over a single Cat-5 Ethernet cable. It is designed to transfer digital audio between a console and a stage or any other remote location, with extremely low latency, across distances of up to 100 metres with appropriate high-performance cables.
What connectors does the NAI48-ES use for its audio inputs and outputs?
The NAI48-ES provides 48 AES/EBU inputs and 48 AES/EBU outputs, all via 25-pin D-sub connectors. This allows direct connection to a wide range of digital front-end devices, including the Yamaha AD8HR 8-channel remote head amplifier for line or microphone input.
How does the NAI48-ES connect to a Yamaha digital mixing console?
EtherSound capability is added to compatible Yamaha digital mixing consoles by installing one or more AuviTran AVY16-ES cards into the console's Mini-YGDAI card slots. A standard Cat-5 Ethernet cable is then run between the console and the NAI48-ES, carrying all audio channels plus remote control signals for compatible devices such as the AD8HR remote head amplifier.
Who makes the NAI48-ES and where does it fit in the Yamaha pro audio range?
The NAI48-ES is made by Yamaha, a Japanese corporation whose Pro Audio division produces equipment for live sound and installation, including mixing consoles, signal processors and amplifiers used across touring, broadcast and venue applications. The NAI48-ES sits within that ecosystem as a network interface designed to extend digital audio connectivity from Yamaha digital mixing consoles to stage or remote locations.
What should I check when buying a used Yamaha NAI48-ES?
Confirm that all 25-pin D-sub connectors are undamaged and that the EtherSound network connection is functioning correctly, as these are the primary signal paths. Check whether any AuviTran AVY16-ES cards or other accessories are included, since these are often required for full system integration. Used listings carry a 21-day warranty covering major functional faults; the buying guide at 10kused.com/used-av-equipment-guide/ covers the full purchase process.
