ESI planet 22c — Compact Dante Audio Interface with Reference-Quality Sound

The ESI planet 22c is a network audio interface made for those who need clean, low-latency audio over Ethernet. With its 2x2 analog I/O, you can connect standard studio or live equipment to a Dante network without complication. The planet 22c stands out for its sturdy construction and straightforward installation, offering all the essentials for modern digital setups.

Professional Features in a Portable Format

BurrBrown PCM1804DB ADC and PCM1796DB DAC chips deliver reference-grade audio conversion in this model. Installation is easy, even in remote racks, thanks to Power over Ethernet (PoE), and the device lets you switch between pro and consumer levels for compatibility with different gear.

Precise Audio Conversion and Flexible Connectivity

For technical users, connecting analog and digital devices reliably is essential. The planet 22c provides high-end conversion and balanced TRS jacks for consistent signal quality throughout studio or venue networks.

• Inputs/Outputs: 2-in/2-out analog balanced TRS — integrates with mixers, instruments, or monitors
• Converters: BurrBrown 24-bit/96kHz PCM1804DB (ADC), PCM1796DB (DAC) — delivers accurate, detailed sound
• Adjust the interface to either professional or consumer signal levels, so you always match your other equipment requirements.

Performance and Audio Quality for Demanding Setups

In demanding AV and studio environments, you benefit from long cable runs and ultra-low latency. The planet 22c transmits lossless audio far beyond USB or standard analog cables, maintaining 20Hz–20kHz ±0.1dB frequency response and dynamic ranges of 110dB/120dB (input/output) for critical listening and measurement needs.

• Use sample rates of 44.1, 48, 88.2, 96 kHz to fit any digital project or workflow.
• Latency: as low as 1 ms — provides real-time performance for live or studio use
• Dynamic Range: Input: 110 dBA, Output: 120 dBA — ensures clean, quiet operation

Practical Design and Power Options

Planet 22c operates via PoE or 12V DC and fits tight spaces at 110 x 110 x 25 mm, weighing only 236 g, so it works for mobile, permanent, or desktop AV setups.

• Power: PoE or 12V DC — select whichever setup fits your installation
• At just 110 x 110 x 25 mm and 236 g, this interface is easy to place or transport for any scenario.
