Page 7: Operation
Audio Amplifier AD301R TEMA TELECOMUNICAZIONI SRL 5. OPERATION Please refer to the following block diagram of the device to describe the system. The "Equalizer" block realized with analog technology manages the inputs, the tone controls, the level signaling on the LED and passing the signals to the final stage of amplification, completely digital, in D class. -
Page 8: Description Of The Connection Terminals
*** Note. The playback will take place on the only SPK output in mono mode because AD301R will add the channel L (IN1) and the R channel (IN2) input, ensuring the exact reproduction of the content of the stereo source. -
Page 9: Installation Examples
Note that the connection of the speakers in parallel (could be the model AD333/30T) reduces the total impedance of the speaker system to 4Ω that however is perfectly suited to the output impedance of AD301R by being able to take all the available power. MAS-AD301R-REV01EN... -

Audio Amplifier AD301R TEMA TELECOMUNICAZIONI SRL 7.2. Basic connection with 4 horn speakers 15W-8 Ohm It is possible to double the number of speakers compared to the previous example in order to have a better sound distribution. However, to comply with the characteristics of the minimum output impedance of the system (minimum 4Ω) it is necessary to adopt a series/parallel connection of the speakers, it is not... -
Page 11: Basic Connection With Use Of The Aa-10/Pa And Aa-11/Pa Interfaces To Send Announcement From Telephone/Pbx
Basic connection with use of the AA-10/PA and AA-11/PA interfaces to send announcement from telephone/PBX An interesting application can be the use of the TEMA AA-10/PA or AA-11/PA interfaces as the audio source, allowing to interface a telephone system with the paging sound system. -
Page 12: Connection With Different Power Speakers On The 100V Speaker Line
Audio Amplifier AD301R TEMA TELECOMUNICAZIONI SRL 7.4. Connection with different power speakers on the 100V speaker line This connection example uses the output transformer AD320/30 which allows to exceed the 30mt limit of cable between the amplifier and the speakers suitable to be connected to the 100V line such as horn loudspeakers AD330/15T and AD330/40T and the rectangular or round speakers AD332/60T and AD333/30T.
