Troubleshooting:- If you observe hum/ noise in your monitors, check these scenarios:-
1. Grounding issue- if there is no proper ground/ reference connection; it may pick up the electrical interference from the atmosphere.
2. Avoid placing audio cables next to high-powered equipment and cables that can introduce the noise
3. Uncoil long audio cables and try to use shorter audio cables.
4. Test a diff. cable and try to connect your computer, interface and speakers to the same power outlet.

2 XLR hybrid inputs – Both channels of studio 2 have Mic/ Instrument combo jacks. This convenient connector accepts either a ¼-inch phone plug or an XLR plug
Microphone Inputs. The XLR inputs on channels 1 and 2 are equipped with two custom microphone preamplifiers.XLR Microphone Instrument inputs: 40 dB of variable gain (-10 to +30 dB).
Instrument Inputs. The ¼-inch TS connectors on channels 1 and 2 are for use with instruments (guitar, bass, etc.). When an instrument is plugged into the instrument input, the mic preamp is bypassed, and studio 2 becomes an instrument preamplifier. TS ¼-inch Instrument Level inputs: 60 dB of variable gain (0 dB to +60 dB)
48v phantom power – . Studio 2 provides 48V phantom power for the microphone input on each channel. Press the 48V button to enable phantom power for all microphone inputs. Note- Do not enable phantom power for a ribbon microphone.
MIDI I/O – MIDI inputs and outputs allow connection to, and communication with, external MIDI equipment. One function of these ports is MIDI sequencing but the MIDI protocol can be used for much more than instruments and sequencing.
Main output – The Main knob controls the output level for the Main Outputs on the back of studio 2, with a range of -80 dB to 10 dB
Headphone output – The Phones knob controls the volume of the headphone output on the rear of the unit. The headphone amplifier is quite powerful, and the volume goes to 11.
Clip Indicator – All channels feature clip LEDs next to the trim controls. The red clip indicator LED will illuminate when the channel’s input signal reaches 0 dBFS. At this level, your mic preamp/line trim signal will exhibit signs of clipping
Mixer – The Mixer knob allows you to blend your input signals with the playback streams from your computer. This allows you to monitor your input signal with zero latency. If the knob is positioned at 12 o’clock, the input signal and the playback stream will be equally balanced. Turning the knob to the left will increase the level of the input signal relative to the playback stream; turning to the right will increase the level of the playback stream relative to the input signal.
USB Port. This is where you connect the USB cable from your AudioBox USB to your computer. The AudioBox USB is bus-powered via this connection and does not require an external power supply. Studio 2 USB is compatible with all types of USB ports (1.1, 2.0, and 3.0).
