Setting Up Your Speakers

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.
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.
YU4 is designed to perform optimally positioned at least 8” from the rear wall in an average listening room. However, it may not be possible to install the speakers in this position and since rooms vary in shape, size, and furnishing, a certain amount of experimentation is necessary to determine the most suitable position.
Moving the speakers very close to the rear wall will enhance the bass frequencies but will tend to reduce soundstage depth, while moving the speakers away from the rear wall will tend to have the opposite effect. Avoid positioning the speakers close to or in the corners of the room, as this will excite undesirable room coupling in the low and middle frequencies. If the width of the rear wall is limited then toe-in the speakers slightly to reduce reflections. Room characteristics and positioning have a profound effect on the performance of the speakers, so time and effort devoted to achieving the optimum positions will be rewarded.
Ensure that the ON/OFF Switch is in the OFF position.
Connect the two speakers together as shown below using the supplied speaker cable. Connect the RED (+) and BLACK (−) terminals from the active speaker (left channel) to the corresponding terminals on the passive speaker (right channel). If you wish to place your speakers farther apart than the supplied cable will reach, we recommend that you purchase a heavier gauge of speaker cable to minimize signal loss.
Follow the instructions on the ensuing pages to connect your audio sources to YU4.
Connect the power cord from YU4’s active speaker to the wall outlet.

ATTENTION
When connecting audio cables the ON/OFF Switch must be turned OFF. After connecting all cables, the unit can be turned ON.
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

YU4 features a high quality DAC (digital-to-analog converter) for the optical inputs that supports data streams up to 24-bit/96 kHz resolution.
YU4 supports Bluetooth 4.0 with Qualcomm® aptX™ technology.
Use the appropriate audio cable to connect your audio source components to your speakers.

• 3.5 mm stereo mini-jack AUX cable
• Stereo RCA to 3.5 mm stereo mini-jack ‘Y’ cable
• Optical Toslink cable

Connecting a Turntable

YU4 features a built in Phono Pre-Amp that allows you to connect directly to a turntable.

• connect your turntable to the RCA L/R inputs on the back of the YU4
• connect your turntables grounding wire to the grounding post (not all turntables feature a ground wire)
• If your turntable does not have a built in Phono Pre-Amp, use the “Phono” setting on the Phono switch.
• If your turntable has a built in Phono Pre-Amp, use the “Line” setting on the Phono switch.

ATTENTION
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

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.
We recommend the Kanto sub6, sub8, or YURI powered subwoofer with crossover and volume controls. Most quality subwoofers offer these controls, which allow you to customize the amount of bass you will experience.
Look for details on the Kanto website at: www.kantoaudio.com

Auto Power-up / Auto Power-down

The YU4 is designed to save power when not in use. When no audio signal has been detected for 15 minutes, the YU4 Amp will put itself into stand-by mode. If the audio signal returns via the same input that the YU4 was playing when it entered standby, the YU4 will wake up and resume playing. It can also be woken up manually by:

• Pressing the Standby Button on the Remote
• Pressing the Control knob

If you do not find the Auto Power-up (APU) feature useful, you can disable it by pressing the Balance Reset button on the remote and holding it for 5 seconds. The Status LED will blink once to indicate that you have disabled the APU feature. To enable the APU if you have disabled it, simply press and hold the Balance Reset button again for 5 seconds. The Status LED will blink twice to indicate that you have enabled the APU.
Note that APU is always turned on when power is applied, but will only work after automatic power down. APU will not work if unit is manually switched to standby using the remote or control knob.
Note that APU function will not work when using the Bluetooth input.

Bluetooth® Pairing

YU4 features Bluetooth 4.0 with Qualcomm® aptX™ technology and can be paired with many devices for wireless audio playback from your phone, MP3 player or tablet. Pairing is easy.

1. Press the Bluetooth button ( ) on YU4’s remote to select it as the input source. The Bluetooth LED (blue) will flash to indicate that YU4 is in pairing mode.
2. Enable your Bluetooth device to search for a new device to pair with. Select ‘YU4 by Kanto’ from the list of Bluetooth devices available for pairing.
3. If pairing is successful, the Bluetooth LED (blue) will remain solid. You will not need to pair the same Bluetooth device again – ‘YU4 by Kanto’ will remain on your device list until you remove it from the list.
4. If the device does not pair with YU4, turn the speaker’s ON/OFF Switch to the OFF position, then repeat Steps 1 to
5. Alternatively, you can press the Bluetooth reset button ( ) on the remote or turn off Bluetooth on your device and turn it back on again.

Bluetooth® Operation

1. We recommend keeping a maximum distance of 10 meters between the speaker and your device.
   The best signal fidelity is within this range.

2. You can stream audio from your device to the speaker using either the player control buttons of your device or the control buttons of the remote control (see diagram of Remote Control on page 5 of this manual – buttons #20, #21, and #22).

3. Take note of the following behavior and functionality during Bluetooth operation. When you are successfully connected, the Blue LED will be lit solid, and your device will show as connected to ‘YU4 by Kanto’.
   • 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.
   • When the speaker is put in Standby mode or powered OFF, Bluetooth connection with the device is lost. When the speaker returns to Playback mode, the Bluetooth connection between the speaker and device is re-established. However, you may notice a choppy playback signal for approximately 30 seconds after reconnection. It will normalize.
   • While the speaker can be paired with more than one device, only one device can play and transmit audio signal at a time.

4. The YU4 remote control features a Bluetooth Reset button to quickly disconnect a paired device and allow a second device to pair with the speaker (button #7 on the Remote Control diagram on page 5).
   • Press Bluetooth Reset button to disconnect a paired device.
   • Follow the pairing instructions to pair another device.
   • The same behavior and functionality apply to the second device.

USB Charging Operation

YU4 features one 5V 1.0 A USB charging port on the back panel. This is a convenient power source to charge your devices.
When YU4 is in Playback Mode (LED White) and Standby Mode (LED yellow), the port is active, and whatever device is connected is able to draw up to 1.0 A of power.
