High durability, Space saving and Quality sound Mono power amplifier


With the High quality sound development philosophy which Onkyo has cultivated through its 70 years over experience in consumer audio business, this air-forced ventilation adopted 120 watt mono power amplifier is designed for longevity, adding the high durability designing standards necessary for professional use, such as protection circuit guards against heat and overcurrent etc. Also, it cares about flexibility in the installation place, having the side air-forced ventilation allowing the direct stacking for rack mount setting etc.




Various speaker connection possible by Lo-Z and Hi-Z compatibility


Compatibility with High impedance connection (100V/70V selectable) and Low impedance connection (2/4/8 ohms selectable). Flexible selection of the number of speakers and type (Hi-Z/Lo-Z), depending on the size, purpose and category of the installation location.




Flexible system expansion to cater for various size shop fronts


Each commercial space are different and sometimes walls and pillars might create dead space where sound can not be reached. Additional number of speakers can be connected by adding PCA1120 to MCA1120(sold separately) and make daisy-chained connection to solve these dead space problem and realize comfortable music playback. Multiple connection of Mono power amplifier PCA1120 is possible (e.g. 2sets expansion, 3sets expansion), so its easy to cope with future expansion of the store spaces.




Speaker EQ for optimized music playback adapting to various speaker characteristics


Speaker EQ has preset EQ optimized for various manufacturers commercial speakers. Optimization of non preset speakers are also possible by utilizing DSP functions such as 12 band Parametric EQ, HPF(High Pass Filter) and LPF(Low Pass Filter). ※Speakers for Preset EQ are planned to be updated.

■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 PCA1120?


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.




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.




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)
