The dBbox3 is a portable test instrument for monitoring, metering and generating analogue, AES/EBU and S/PDIF audio.

Its five-button interface combines audio, timecode, MIDI and cable-testing tools in a unit with a built-in loudspeaker, microphone and battery or mini-USB power.

Features

• Monitoring of line- or microphone-level signals through the built-in loudspeaker or headphones.
• AES sample-rate, status and error analysis, plus steady tone, sweep, GLITS, EBU and pink or white noise generation.
• LTC reading and generation at 24, 25, 29.97 and 30 fps, with up to 80 ms mono or 40 ms stereo audio delay.
• Phantom-power testing and two-wire audio monitoring.
• MIDI transmission, reception and analysis, and XLR, BNC and MIDI cable testing.
• A/D and D/A conversion, microphone preamplification with 48 V phantom power and four-wire-box operation.
