A volume above 80 decibels can be harmful to hearing. When the volume exceeds 120 decibels, direct damage can even occur. The chance of hearing damage depends on the listening frequency and duration.
Yes, bluetooth is a universal method that allows different devices equipped with bluetooth to connect to each other.
Bluetooth is a way of exchanging data wirelessly between electronic devices via radio waves. The distance between the two devices that exchange data can in most cases be no more than ten metres.
HDMI stands for High-Definition Multimedia Interface. An HDMI cable is used to transport audio and video signals between devices.
A slightly damp cleaning cloth or soft, dust-free cloth works best to remove fingerprints. Dust in hard-to-reach places is best removed with compressed air.
Dolby Atmos is a technology that ensures that the sound is reflected from the ceiling to where you are listening. This makes it possible to create a 5.1 effect with only 1 speaker.

To ensure a safe and efficient connection, start by disconnecting the negative terminal of the car's battery. Then, follow the provided wiring diagram in the manual to connect the power, ground, and remote-on wires to their respective terminals on the amplifier.
The Pioneer GM-A4704 is capable of delivering up to 520 Watts in total (130 Watts x 4 channels) when connected to a 4-ohm load. However, do refer to the manual for specific power output details at different impedance levels.
The gain controls are essential for achieving clean and distortion-free sound. Start by setting all the amplifier's gain controls to their minimum position. Then, gradually increase the gain until you reach the desired output level without introducing any distortion. Consider consulting the manual for detailed instructions on gain adjustments.
Yes, you can bridge the GM-A4704 to combine two channels and power a subwoofer. By bridging channels 1 and 2, or channels 3 and 4, you will effectively create a more powerful 2-channel amplifier. Ensure you follow the bridging instructions in the manual to avoid damage and optimize performance.
If you encounter any issues, start by checking the basics such as ensuring the power and ground connections are secure. Next, examine the fuses to ensure they are intact. If the problem persists, consider verifying your speaker connections and consulting the troubleshooting section of the manual for further guidance on identifying and addressing the specific issue.
Yes, the Pioneer GM-A4704 has a high pass filter. This means that it can filter out low-frequency signals, allowing only high-frequency signals to pass through. This can be useful for eliminating bass frequencies from smaller speakers.
Yes, the Pioneer GM-A4704 has a low pass filter. This means that it can filter out high-frequency signals, allowing only low-frequency signals to pass through. This can be useful for sending bass frequencies to a subwoofer.
The total harmonic distortion (THD) of the Pioneer GM-A4704 is 0.05%. This is a relatively low value, indicating that the amplifier produces a clean and accurate sound.
The maximum power output per channel at 2 Ohm for the Pioneer GM-A4704 is 130W. This is a decent amount of power, allowing for loud and clear sound reproduction.
The Pioneer GM-A4704 has 4 audio RCA inputs. This is convenient for connecting multiple audio sources, such as a CD player, MP3 player, or smartphone, to the amplifier.

Question and answer
Number of questions: 1What does Pioneer mean on their speaker wiring diagrams with 2 channel mono and 2 channel stereo? I'm trying to figure out 2 channel bridged operation of a GM-A4704 and they don't specify which diagram to use for bridged operation. Also in this operation, do I wye each L and R RCA so both L inputs channels A and B have that channel's input filled?
