Frequently Asked Questions

Yes, optional rack mount kits are available for these models. The part number is IRK-44-3 and it works for either model. The kit can be used to rack mount one or two units. It is a 1U rack mount.

The MCA1120 and PCA1120 can be stacked using the IRK-44-3 rack mount. Please allow a minimum of 1-inch if free space on each side of the unit for proper ventilation.

It has a built in forced air cooling fan system. Please make sure both sides of the amplifier have space available for adequate intake and exhaust when installing this unit.

It means that the MCA1120 and PCA1120 are capable of driving speakers with a combined impedance as low as 2 ohms. For example, four sets of 8 ohm speakers can be connected parallel as they would have a combined impedance of 2 ohms. You could also connect three sets of 6 ohm speakers (2 ohms combined) or two sets of 4 ohms speakers (2 ohms combined) in parallel.

Yes. However, when speakers are connected the total impedance cannot be less than 2 or 4ohms (depending on setup SW #9). For example, if you connect two of 8 ohm speakers, you can't connect 70V speakers using the 4 ohms setting. If you connect two of 8 ohm speakers, you have 60w of power remaining for 70V, at the 2 ohm setting.

You can daisy chain up to ten PCA1120 units in total. That is you can have one MCA1120 and ten PCA1120 connected together.

Yes. But we recommend using microphones with ON/OFF switch. When using Microphone Ducker function, please switch to the microphone to OFF doesn't collect and amplify unwanted noise.

Only one Bluetooth device can be connected to this unit to play back music. Multiple Bluetooth devices can not be connected at the same time. However, the MCA1120 will memorize the last eight paired devices, so it will be easier to connect in the future. If you have paired more than nine Bluetooth devices the oldest device will be deleted from memory.

The MCA1120 uses works in the 2.4 GHz frequency band for Bluetooth communication. This frequency band is shared by other devices such as microwave ovens and routers. If you experience interference you may need to relocate something.

No, the USB jack found on the MCA1120 is to supply power (5V/2.1A). It cannot be used to play back music.

Stereo play back is not possible. This unit is designed for monaural playback only.

There are 4 modes; "Natural" mode is for general background music playback for most environments, "Calm" mode is for a relaxing atmosphere, "Lively" mode for upbeat sound that is great for a gym or club and OFF mode. The MCA1120 will create an optimized sound field for each environment utilizing psychoacoustics and our proprietary acoustic technology and know-how.
