Product Usage Instructions

To use the MINI Processor (ABOX 1004N) effectively, follow these instructions:

Ensure the device is connected to a suitable power supply with DC12V.
Connect your audio sources to the appropriate input channels, either MIC or LINE.
Adjust the input gain according to your requirements using the provided 7-level control.
If using condenser microphones, activate the phantom power by setting it to 48V.
Monitor the audio output levels and adjust the amplification accordingly. The maximum output levels are MIC Channel 18dBu and LINE Channel 24dBu.
For optimal audio quality, ensure the input and output impedance are balanced and set within the specified ranges.
To minimize background noise, keep the device away from electromagnetic interference sources.
When connecting multiple audio sources, maintain channel isolation to avoid interference by adjusting the settings as needed.
The MINI Processor supports a sampling frequency of 48KHz, providing accurate audio reproduction across the audible range.
For reference, refer to the provided dimensions (WxDxH) to determine the appropriate placement for your setup.
To measure the Total Harmonic Distortion + Noise (THD +N), use the specified input levels (MIC Channel 4dBu, LINE Channel 4dBu).
Take advantage of the wide dynamic range (114dB) for clear and detailed audio output.
If using A-weighted measurement, refer to the EIN values at 1KHz and 80Hz to assess the device’s noise performance.
Ensure the power consumption remains within the rated limit of 100W to avoid any issues.

The MINI Processor

Built-in echo cancellation, feedback suppression and noise algorithms.
Using a stable two-way simultaneous speech (Double Talk) detection method to effectively eliminate excess echoes even in strong background noise and non-linear distortion environments.
Noise suppression algorithm can quickly and accurately track environmental noise changes and maintain good output sound quality.
A total of 10-way input signal interface, full-featured audio adjustment module.
Providing eight MIC inputs + two line inputs + four outputs, supporting gain adjustment, 48V fantasy power supply, built-in preamplifier, signal generator, expander, compressor, 5-band parametric equalization, 31-band graphic equalization, delay, crossover, limiter and other functional modules.
Built-in PC-based control software.
