Frequently Asked Questions - S2-CT Sonifex
How do I connect a microphone to the Sonifex S2-CT?
Connect the microphone to one of the XLR mic inputs on the rear panel. Use a balanced XLR cable for best signal quality. After connecting, gradually increase the channel gain until the input level LED shows a healthy signal.
Can I use condenser microphones with this mixer?
Yes, the phantom power switch provides +48V to power condenser microphones. Make sure the switch is enabled on the channel you are using. Always disable phantom power when connecting dynamic microphones to avoid damage.
How do I prevent audio feedback in live applications?
To minimize audio feedback, keep microphones away from speakers, reduce the gain on channels that are likely to feed back, and use the equalizer to cut resonant frequencies. Also, lower the master volume before making any adjustments.
What is the proper way to set input gain levels?
Start with the channel fader at unity gain (marked 0 dB). Gradually increase the input gain knob until the signal peaks around 0 dB on the LED meter. Avoid pushing into the red, as this can cause distortion.
Can I mount the S2-CT in a standard 19-inch rack?
Yes, the S2-CT is designed for 19-inch rack mounting. It includes rack ears on both sides. Use four screws on each front ear to secure it in a standard equipment rack.
How should I clean and maintain the mixer?
Disconnect the power before cleaning. Use a soft, dry cloth to wipe the surfaces. Never use solvents or abrasive cleaners, as they may damage the front panel. Regular dusting keeps the controls free from debris.
What should I do if the mixer is not powering on?
First, check the mains power cable and the outlet. Then verify that the power switch is in the ON position. If it still doesn't power up, inspect the fuse inside the power inlet and replace it if necessary. If the problem persists, contact a qualified service technician.
Are spare parts available for this mixer?
Yes, Sonifex provides replacement parts such as knobs, faders, and power supply units. Contact your local authorized Sonifex dealer or the manufacturer's support team to order the specific parts you need.
Does the mixer have a built-in power supply?
Yes, the S2-CT includes a built-in universal power supply that accepts 90-240 V AC. This simplifies installation and eliminates the need for an external power adapter.
Can I record the output directly to a computer?
You can connect the balanced XLR main outputs to an audio interface or a computer with a line input. Use high-quality cables to avoid noise. The mixer does not have a built-in USB interface, so an external audio interface is required.
