Multi-zone is a function that allows a home theater receiver to send a second, third, or fourth source signal to speakers or separate audio systems in different locations. This is not the same as connecting additional speakers and placing those speakers in another room, nor is it the same as wireless multi-room audio.

The Ω symbol is often used instead of writing “ohms”. If both speakers are 8 ohms or more, then the speakers can normally be wired in parallel. If the speakers are less than 8 ohms, then to be safe, you should wire them in series.

Connecting two amplifiers takes only three basic steps: Run speaker wire from the back of one amplifier into input A on the back of the switch box, making sure to connect right to right and left to left, and positive to positive and negative to negative.

The zone 2 feature allows this receiver to send a second source signal to a separate audio system in another location. For example, you can watch a DVD in the main zone, while others can listen to a CD in zone 2 at the same time. An additional audio system (for example, an amplifier) to output the sound in zone 2.

Even if the internal power amp’s impedance is lower than normal, it makes no difference whether speakers are connected or not. It probably is just a reminder for people who have both connected, so that they wouldn’t end up using both at the same time unintentionally.

Pre-outs are used to connect an external amplifier to your receiver so they can power speakers in your Home Theater system. An array of pre-outs allows you to turn your receiver into an exclusive pre-amp/processor by using external amps to power all your speakers.

Distinguished Member. All the pre outs are live regardless of the amp assignments. Simply connect the power amps to the relevant pre outs and the associated speakers to the power amps prior to running the calibration. You do not need to set the receiver up to use the pre outs and the pre outs are always live.

A pre-out allows you to connect an external power amplifier instead of using the amp that’s built into the receiver. It allows a signal to pass through the receiver without amplification, and to instead be amplified by another power source.

Yes, if the receiver has pre-outs (line level outputs). only pre amps work to power a receiver with pre-outs it turns out…. Preamps do not power anything. They have only line level operations.

Most home theater receivers already have a preamp fitted, so a dedicated preamp isn’t necessary. However, if you’re a dedicated audiophile and want to get the best out of your setup, then a preamp would be a good investment.
