Technical Specifications
Connectivity
• Genelec measurement microphone connector.
• Headphones output (6.3 mm stereo jack).
• Stereo analogue balanced line outputs (6.3 mm tip-ring-sleeve connectors).
• Stereo analogue balanced line inputs (6.3 mm tip-ring-sleeve connectors).
• XLR digital audio output, supports AES/EBU (AES3) format.
• XLR digital audio input, supports AES/EBU (AES3) format and SPDIF format when used with a separate 75 to 110 ohm impedance converter.
• GLM management network connection (bottom connector) and GLM network terminator connector needed for long networks (top connector).
• USB type C auxiliary power input for use when the computer USB output cannot supply sufficient power for 9320A.
• Kensington compatible anti-theft lock opening (top).
• USB type C computer interface, used for management, audio input, and power supply for 9320A.
The 9320 uses power from one USB connector at a time. When both connectors are connected, the PWR connector is used for power. The computer USB-C power input limits to 2.5 W input power (500mA input current). When the PWR connector is in used, the output power available to the headphone is
slightly higher; the benefit is +0 dB to 2.5 dB more output, depending on the load impedance. The PWR input connector is designed to work with a standard 5 V 1A USB power adapter.
