Shure SCM800 Microphone Specification

The Shure SCM800 is an eight-channel microphone mixer designed for a variety of professional audio applications, offering flexibility and superior sound quality. Each of its eight channels is equipped with a balanced XLR input, providing phantom power for condenser microphones, and a line-level input for versatile connectivity options. The SCM800 features a wide frequency response range from 50 Hz to 20 kHz, ensuring clarity and natural sound reproduction.

This mixer incorporates Shure's patented IntelliMix technology, which automatically adjusts microphone levels to minimize background noise and feedback, enhancing audio quality in live sound environments. Each channel has an adjustable gain control, allowing precise input level settings, and an LED peak indicator to prevent distortion. A master level control is provided for overall output level adjustments.

The SCM800 supports both manual and automatic mixing modes, enabling users to tailor its operation to specific needs. It includes a mix bus output for cascading multiple mixers, expanding the number of available channels for larger setups. The unit is housed in a rugged, rack-mountable chassis, ensuring durability and easy integration into existing audio systems.

Additional features include low-cut filters for reducing low-frequency noise, switchable mic/line level output, and an internal power supply for reliability. The SCM800 is designed for ease of use, with intuitive controls and clear labeling. Its robust design and advanced features make it suitable for conferences, broadcast, sound reinforcement, and other professional audio applications where reliable and high-quality sound mixing is essential.

Shure SCM800 Microphone F.A.Q.

How do I connect the Shure SCM800 to a mixing console?

To connect the Shure SCM800 to a mixing console, use balanced XLR cables. Connect the outputs of the SCM800 to the inputs of the mixing console. Ensure that phantom power is turned off on the console if it is not needed.

What is the best way to set gain levels on the SCM800?

Start by setting all channel gain controls to the minimum. Then, adjust each channel's gain while speaking into the microphone until the desired level is achieved without distortion. Use the peak LED as a guide to avoid clipping.

How can I reduce feedback when using the SCM800?

To reduce feedback, position microphones away from speakers, lower the gain, and use directional microphones. Additionally, adjust the equalization to cut frequencies that are prone to feedback.

What should I do if there's no sound coming from the SCM800?

Check all cable connections to ensure they are secure. Verify that the power is on and that the output level is not set to zero. Also, inspect the channel mute buttons and ensure they are not engaged.

Can I use the SCM800 with condenser microphones?

Yes, the SCM800 can be used with condenser microphones. Ensure that phantom power is enabled on the channels where condenser microphones are connected.

How do I perform a factory reset on the SCM800?

The SCM800 does not have a factory reset function. To restore default settings, manually adjust each control to its default position as specified in the user manual.

What maintenance is required for the SCM800?

Routinely clean the unit with a dry cloth to remove dust. Check all connections and cables for wear. Regularly test the unit to ensure all channels and functions are operating correctly.

Is it possible to link multiple SCM800 units together?

Yes, multiple SCM800 units can be linked together using the Link In and Link Out connectors. This allows for expanded channel capacity across units.

How can I improve the sound quality of my SCM800 setup?

Ensure proper microphone placement and selection for your specific application. Use high-quality cables and minimize interference by keeping signal paths clear of power cables.

What should I do if a channel on the SCM800 is not responsive?

First, check if the channel is muted or if the gain is set too low. Test the microphone and cable with another channel to rule out equipment issues. If the problem persists, consult the user manual or contact Shure support.
