YU4 is equipped with a RCA connector to provide output signal to a powered subwoofer. Simply connect a single RCA cable from the SUB OUT connection on the YU4 to the AUDIO INPUT on your subwoofer. If your subwoofer has a stereo L/R RCA input, either input will work.

The YU4 has power-saving features with its efficient Signal Detection that will automatically place the unit on standby or to power up when in use. Use the knob at the front of the remote control that comes with the speakers. The remote lets you control volume, tone, inputs, and balance when you connect your devices via Bluetooth. Value for Money – 4.8 out of 5 The connection between speaker and device remains active even if input source has changed. For instance, you can switch to another input source (e.g. RCA) and return to Bluetooth operation without losing signal connection and, therefore, do not need to pair with the device again. The Edifier R1280DB is a Bluetooth 5.0 speaker made for audiophiles. It comes with high-end components, the latest Bluetooth version, and plenty of inputs (optical audio, coaxial and line-in inputs).

Many factors will help you say that a desktop speaker is easy to use. First, it should be easy to assemble or install on your PC or audio equipment. Next, it has to provide easy access to cords and cables. Also, the speaker should be easy to adjust with controls at the front or with remote control. Lastly, the speakers should be easy to prop up, install on a bookshelf or wall. Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited. The space between the two speakers and the distance from the listener is important. If the speakers are positioned too close or too far apart, stereo imaging will not be fully developed. Here we place the Kanto YU4 virtually next to a standard width amplifier and turntable on a BDI Octave Media Cabinet to get a better idea about the size. One of the natural alternative to the Kanto YU4 is the YU6 which is located one step higher in Kanto's Powered Bookshelf selection.

Controls are limited and may take time to learn. We recommend using the remote control instead of the knob. Adjacent to it is an LED light that tells you that the speakers are powered on. Design – 4.8 out of 5 Reconnect the speaker wire between the active speaker and passive speaker and ensure the ends of the speaker wire are fastened securely through the binding posts.When using AUX with a PC, reduce the volume of the speakers and increase the PC volume. Also try connecting the speaker ground terminal to the PC chassis ground if noise persists. Some models of turntables include a built-in Phono Pre-Amp. If your turntable has a built in Phono Pre-Amp, DO NOT use the Phono setting on the RCA switch. Doing so will void your warranty and could cause severe damage to your speakers. Connecting a Subwoofer Set the volume of the source to its highest level. Low source volume can negatively affect dynamic range.

While the speaker can be paired with more than one device, only one device can play and transmit audio signal at a time. We recommend keeping a maximum distance of 10 meters between the speaker and your device. The best signal fidelity is within this range.When the volume is high, this system can produce noise levels that could permanently damage your hearing. YU4 is a self-powered speaker system. Do not connect the speaker terminals to the speaker intputs of a stereo amplifier. Damage may occur. Use only the power cord provided with the speakers. Connecting Audio Sources

Kanto YU4 comes with a handheld remote which is obviously very useful to control your powered speakers from a distance.Verify that the volume of the speaker is not at its minimum level. Turn the volume up using the knob on the front or the volume controls on the remote. The Audioengine HD3 wireless speaker can connect to any Bluetooth-capable device even from 100 feet away. This works with all types of devices and equipment including old-style turntables, TVs, laptops, desktops, and gaming consoles. Verdict The YU4 powered speaker system is designed for either bookshelf or stand mounting. The stands should be of rigid construction, between 26" to 32" high. We recommend the Kanto SP26 speaker stands to go with your YU4.
