   2. Rec  - Recorder : The port connects to the input audio signal - Audio In of the receiver.
4. Pre Out : Audio output port as a pre-amplifier - small-level audio amplification, used to connect to other audio amplification devices.
5. Speaker Systems : Ports for connecting speakers.
6. AC Outlets : Power supply ports for other surrounding devices such as CD/VCD/DVD players,. these are power supply ports that are turned on/off through the Amply's On/Off switch.

How to connect Speakers to Hi-Fi Stereo Amplifier

Connect Speakers to Amply

The port to connect to the speaker, is divided into two connecting stations A and B, each station has 4 connection ports for Negative (-) and positive (+) signals of the two left channels - L/Left and right - R/ Right. When connecting to the speaker, you need to pay attention to connect the correct color or the correct symbol on the connection ports of the Amply and the speaker.

Two docking stations will allow connection to 4 speakers, 2 left speakers and 2 right speakers. If there are only 2 speakers, please connect to station A. 

1. This is just a normal speaker connection, other connections for more complex audio systems will be covered in other articles.
2. The position of the left and right speakers is calculated according to the position of the listener, not the position of the Amplifier.
3. It is necessary to use the right type of wire to connect the speaker to the Amplifier with the connection ports of the Speaker and Amply. Some connection ports allow the use of bare wire ends, just remove the plastic insulation at the end of the wire, then attach it to the connection port and tighten it.
