To connect the adastra A22 amplifier to your speakers, follow these steps:
1. Identify the speaker outputs on the amplifier. There are two speaker outputs, each labeled with a positive (+) and negative (-) terminal.
2. If you are using two 8Ω speakers, connect one speaker to each output by inserting the positive wire into the positive terminal and the negative wire into the negative terminal. Ensure that the polarity is correct for both speakers.
3. If you prefer to use a single 8Ω or 4Ω speaker, connect it to either one of the speaker outputs. Again, make sure to connect the positive wire to the positive terminal and the negative wire to the negative terminal.
4. If you plan to use the FM tuner, it is recommended to connect an external FM aerial to the "FM ANTENNA" F-connector on the amplifier. This will improve the reception of FM radio signals.
5. The A22 amplifier offers multiple line inputs for connecting various audio sources. You can connect devices such as a CD player, laptop, mp3 player, or TV tuner to the RCA sockets labeled "AUX 2" and "AUX 3".
6. Additionally, there is an extra line input labeled "AUX1" on a 3.5mm stereo jack located on the front panel. You can use this input to connect another audio source using a compatible cable.
7. If you need to make announcements or use a microphone, the A22 amplifier has a 6.3mm mono jack that accepts a microphone input. Simply plug your microphone into this jack to use it.
8. If you want to connect the A22 amplifier to another amplifier or audio system, there are a pair of RCA connectors on the rear panel labeled "LINE OUT". You can use these connectors to link the signal mix of the A22 onto the input of the other amplifier.
