How do I match my speakers to my power amp?
A general rule for choosing an amplifier is to select an amp that provides 1.5-2 times the continuous power rating of your speaker. This will ensure the speaker has enough power while leaving yourself 3 dB of headroom.

How do STEREO, PARALLEL, and BRIDGE modes operate?

STEREO: Each channel operates independently. Input signal and attenuator are also separated between each channel.
PARALLEL: Input signal is connected to only a single channel, and the same output signals are obtained from two adjacent channels. Attenuator operates independently.
BRIDGE: Two channels of power amp output work as a single channel with doubled output. Only a single attenuator operates. The voltage gain will be increased by 6dB, and the minimum load impedance will be doubled. For details on connecting the speaker output, please refer to the manual that came with each power amp.

What is rated output power?

Rated output power is the RMS (root mean square) or effective value of electric power that can be delivered continuously for several ten seconds to few minutes. The unit is W (Watt).
It is not a value that can be output continuously for a long period, but it would not matter in a practical operation because music signal and voice speech signal are generally not constant in level. When a signal like continuous sine wave is continuously driven at the rated output, the thermal protection circuit will be activated, which will reduce the output power to around 1/8 (-9dB).

What is input sensitivity?

it is the required input signal level to obtain the rated output when attenuator is in its maximum (generally 0dB). It also means the output signal will be clipped if a signal larger than the input sensitivity is being input with the attenuator at maximum. When the voltage gains are the same, the larger output model is, the larger its input sensitivity is, too.
If the load impedance is halved, the output power will be almost doubled since the voltage gain is constant. In this case, however, the input sensitivity will be a little smaller because the actual rated output will not be doubled.

What is the maximum input level?

The maximum input voltage that can be applied to the device without any clipping. The unit is mostly dBu.
If the input signal exceeds the value, it will be clipped even when the attenuator is turned down.

What is S/N ratio?

The difference between maximum output level and the background noise level without input signal in the unit of dB. The larger the value, less affected by noise, ie. better performance.
Generally, there is not much difference between the noise levels in the same series of power amps, so the model with larger output has better S/N ratio.

When rack mounting multiple power amps, is it necessary to leave space between each amp for heat dissipation?

Current models for all Yamaha power amps have cooling fan installed. Therefore, as long as the front and back of the rack are open, it is not necessary to leave any space between each amp when mounting.

To connect multiple speakers, which of parallel or serial connection is recommended?

When connecting multiple speakers with a single power amp, either of parallel or serial connection can be used.
Generally parallel connections are more common, but the combined impedance of the speakers will become half for two speakers, and 1/4 for four speakers. Therefore, it is necessary to be sure that the impedance would not be lower than the load impedance supported by the power amp.
In serial connection, the combined impedance will be simply calculated by adding all the speaker impedances. In order to drive many speakers, it is recommended to combine serial and parallel connections.

What is damping factor?

It is a specification of power amps and calculated by the following formula: speaker load impedance / power amp output impedance.
Larger value is better. It is also said how efficiently the electric current flows into the speaker unit.
The damping factor in actual use can be calculated as follows: speaker load impedance / (power amp output impedance + (round trip) resistance of speaker cables)
This implies the cross-sectional area and length of the speaker cables significantly affect the factor.
Speakers produce sound by vibrating the diaphragm with the electric power from power amp. However, because of the vibrating part weight and the damper elasticity, it is like hanging a weight on a spring. Even if the audio signal is stopped, the vibration will not be able to stop so quickly. It is more obvious on the woofer with heavy weight. The vibration will produce electromagnetic induction and result in electric power, but the electric current caused by the induction will be counter force to the vibration. If the induced current is shorted with low resistance as much as possible to maximize the power to suppress the vibration and strengthen the power of spring, the unwanted vibration will be converged quickly which will produce a sharp sound.

What is voltage gain?

Voltage gain refers to the ratio of the output voltage to its input voltage when the attenuator of the power amp is set to its maximum (generally 0 dB).
As long as power amps have the same value, even if they have different rated output power, the same input level will generate the same output level until each power amp reaches the rated output. In this case, the different rated output causes the difference in input sensitivity.
When driving speakers in multi-amp mode with speaker processors, if the voltage gains for the power amps are different, the speaker preset recommended by the manufacturer will not function properly.

If my amp has both an XLR connector and a phone connector for the input, can I send a signal input from the XLR connector through the phone connector to the next amp?

Yes. Audio signal can be sent through either connector because the XLR connector and phone connector are internally connected in parallel. However, audio signals cannot be mixed by inputting the signals from both connectors. If your amp has an XLR connector and Euroblock connector for the input, audio signal can be sent through either connector as well.
