Frequently Asked Questions - 202 Go Audibax

How do I power the Audibax 202 Go mixer?

The mixer can be powered via the USB port using a computer or a USB mains adaptor (5 V / 500 mA, not supplied). Connect the [USB TO COMPUTER] port to a power source.

How do I pair a Bluetooth device?

Press the [PAIR] switch. The blue LED will blink once per second, indicating pairing mode. On your Bluetooth source, scan for devices and select 'Audibax 202 Go'. Once connected, the LED blinks once every 5 seconds.

How do I use phantom power?

Phantom power (+18 V) is permanently active on the XLR input of channel 1. It powers condenser microphones. Use only balanced XLR cables to avoid short circuits.

Can I connect a headset with microphone?

Yes, connect the headset to the [MONITOR - HEADSET] (headphone) and [MONITOR - MIC] (microphone) jacks. The microphone signal is processed via channel 1.

How do I use the mixer as a USB audio interface?

Connect the [USB TO COMPUTER] port to your computer. The mixer is USB 1.1 compatible with 16-bit/44.1-48 kHz audio. The main mix signal is sent to the USB output.

What do the EQ controls do?

Channel 1 has [HIGH] (treble ±15 dB @ 12 kHz), [LOW] (bass ±15 dB @ 80 Hz), and [PAN] (left/right balance). Channel 2/3 has similar EQ and a [BAL] control for stereo balance.

How do I assign signals to Monitor or Main Mix?

Use the [2-TK / BT TO] switch to send Bluetooth and 2-TK input signals to Monitor (pressed) or Main Mix (released). The [LINE / USB - TO] switch sends the channel signal to Monitor or Main Mix.

What should I do if the PEAK LED lights up?

The [PEAK] LED indicates overload in channel 1. Turn the [GAIN] control counterclockwise until the LED goes out to prevent distortion.

How do I clean the mixer?

Disconnect the unit from power. Use a dry, lint-free cloth to wipe the surface. Do not use liquids, solvents, or abrasive cleaners. Avoid getting moisture into openings.

How do I dispose of the device properly?

The product is subject to the WEEE directive. Do not dispose with household waste. Take it to an approved recycling facility or contact your local waste disposal service.

1 Signal
2 Ground, shielding

In a professional environment, therefore, the balanced transmission is preferred, because this enables an undisturbed transmission of signals over long distances. In addition to the conductors 'Ground' and 'Signal', in a balanced transmission a second core is added. This also transfers the signal, but phase-shifted by 180°.

Since the interference affects both cores equally, by subtracting the phase-shifted signals, the interfering signal is completely neutralized. The result is a pure signal without any noise interference.

7 Plug and connection assignment

Introduction

This chapter will help you select the right cables and plugs to connect your valuable equipment in such a way that a perfect sound experience is ensured.

Please note these advices, because especially in 'Sound & Light' caution is indicated: Even if a plug fits into the socket, an incorrect connection may result in a destroyed power amp, a short circuit or 'just' in poor transmission quality!

Balanced and unbalanced transmission

Unbalanced transmission is mainly used in semi-professional environment and in hifi use. Instrument cables with two conductors (one core plus shielding) are typical representatives of the unbalanced transmission. One conductor is ground and shielding while the signal is trans-mitted through the core.

Unbalanced transmission is susceptible to electromagnetic interference, especially at low levels, such as microphone signals and when using long cables.
