■[Details of the 3 new features]

1)Bluetooth® Master Mode

This mode allows only certain device to connect (e.g. Café owner’s tablet).

2)Bluetooth® Hotel Mode
Like in hotel rooms where you can playback your favorite music as a background music, this mode will erase all previously paired device history when the customer check-out from the hotel and leaves the room.
It will avoid unintended connection with the amplifier in the room they have stayed in the past, even when the same customer comes back and stays in another room within the Bluetooth® connection range. 
3)Bluetooth® Friendly Name changing function
Installers can change the amplifier’s preset name [Onkyo MCA 1120] displayed on the customer’s device to any preferred name, when connecting to Bluetooth® (Pairing). Facilities like hotels where multiple amplifiers are installed, it will be easier for the customers to identify the unit by replacing the Friendly name to [Hotel name + room number] etc.

■Frequently Asked Questions

Can it be purchased by ordinary general users?

This is a commercial use equipment and can only be purchased by special dealers with installation capability.

Are there any rack mount kits available for the MCA1120?

Yes, optional rack mount kits are available for these models. The part number is IRK-44-3 and it works for either model.

What type of cooling does this amplifier use?

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.

What is the meaning of low impedance drive capability down to 2 ohms?

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.

What is the difference between Mic Ducker function and Mute function during Microphone usage?

When there is an input signal from the microphone (MIC), Mic Ducker function will automatically lower 20dB from other inputs and recovers the volume level when there are no MIC input (can be used on both MIC1 ands MIC2 input). It will be useful to use this Mic Ducker function if you are using this unit for back ground music playback in the store. Microphone Mute function can be used when connecting normally open contact closure equipped microphones, and will manually mute (totally off) other inputs. Please refer to the Q&A below for more details.

Can you mute (totally off) the background music when using the microphone equipped with talk switch?

Mute function can not be used with ordinary microphone with ON/OFF talk switch function. Mute function can be used only with microphones having special wiring with talk switch linked remote terminal (non-voltage dry make contact) often used in broadcasting facilities. Function name depends on each microphone brands, so please check with your microphone manufacturer for details. This function is only available for MIC 1 input. It will be useful to use this mute function if you are using this unit for announcement in the office etc.

Can I use an ordinary hand-held microphone (without push-to-talk switch)?

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.

How many Bluetooth devices can be connected simultaneously?

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.

Can you play back music stored inside the USB memory device using this the MCA1120's USB jack?

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

Can you supply power to Laptop PC etc. using this unit's USB power supply terminal?

Power supply capability is up to 5V/2.1A, and can be used to supply power to ordinary tablets and portable players. It can not be used to supply power to USB 3.1 Laptop PC etc.

Can I play back music in stereo?

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

What kind of function is Speaker EQ?

Speaker EQ is a function that has preset high pass filter settings optimized for various speaker characteristics of standard speakers popular in the professional market. Compatible models are planned to be updated and added from time to time. Simplified model list is described inside this unit's leaflet, but please contact our sales person for more details. Standard high pass filter setting is prepared for other speakers not listed, so you can rely on having a non distorted sound from any speakers connected.

How does the BGM sound mode work?

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.

How to use Remote Volume function?

This function is to control volume from distant location apart from this unit's installed place. Please connect external variable resistor type (10k ohms type) volume controller. Control from external controller and main unit will be linked and not mutually exclusive.

How to use RS232 terminal?

This is a designated terminal to send touch panel etc...'s wireless control command from PC to this unit. It can be connected using PC's RS232 to stereo mini plug ( 3 pole, 3.5mm) conversion cable. Please contact your system integrator who can setup UART control system for more details. For system integrators, please contact us so that we can supply details of the command information.

How to use IR terminal?

This terminal is for using ordinary remote controller (infra-red type) to control this unit. Connect the external remote receiver (IR emitter) using monaural mini plug (2 pole, 3.5mm). There are no power supply function for the external remote receiver, so please prepare it separately. Please contact us for details of this unit's remote control signals. There is no remote controller receiver built into this unit, so remote controller is not supplied as accessories. IR terminal control can not be used together with UART control of the RS232 terminal. (UART control will be the priority)
