HOW TO SET UP

GETTING STARTED WITH WIIM ULTRA
Before using your WiiM Ultra, follow these steps to set it up:

1. Connect to Audio Device: Attach the WiiM Ultra to your audio device.
2. Power On: Turn on the WiiM Ultra.
3. Download the App: Install the WiiM Home App on your mobile device.
4. Network Connection: Use the companion app to connect the WiiM Ultra to your network.
5. Configure Settings: Adjust the settings within the app to suit your preferences.
   By completing these steps, your WiiM Ultra will be ready for use.

CONNECT WIIM UTRA'S AUDIO OUT PORT
The WiiM Ultra offers six distinct audio output interfaces to connect your DAC, amplifier, headphones, stereo receiver, and powered speakers. These include:

• Analog LINE Out
• Digital Optical (TOSLINK)
• Coaxial
• USB
• Headphone Out
• Sub Out

Please note that the WiiM Ultra outputs audio to only one of these interfaces at a time, aside from the optional Sub Out.

Setting Up WiiM Ultra's Audio Output:
(Note: Perform steps 3, 4, and 5 after installing the WiiM Home App)

1. Depending on your preferred audio equipment, select the appropriate connection method: RCA cable, optical cable (TOSLINK), COAX, USB, or headphone.
   1. For RCA cable, plug it into the LINE OUT port on the back of the WiiM Ultra.
   2. For optical cable (TOSLINK), plug it into the OPTICAL OUT port.
   3. For Coaxial cable, plug it into the COAX OUT port.
   4. For Sub OUT port, please connect 75-ohm impedance cable.
2. Connect the other end of the cable to your audio equipment (DAC, amplifier, Subwoofer, or powered speaker).
3. Within the WiiM Home App on your iOS or Android device, designate the desired output port. Remember that the WiiM Ultra only outputs audio through one of these options. If subwoofer is connected, please turn on the subwoofer in the device setting.
4. Enhance sound quality with customized sound equipment connection:
   1. EQ settings
   2. Calibration (latency from the WiiM Ultra to speaker)
   3. Test music playback to see the maximal audio resolution your downstream audio device supports.
5. You're now ready to begin playing audio on your selected output devices.

Notes:

• Selecting the appropriate audio output port is crucial to ensure sound output. Incorrect selection may result in no audio.
• For bit-perfect audio output, opt for the digital audio output and activate the fixed volume output, disable EQ and mono audio in the WiiM Home App's device settings.
• You have two ways to control the volume of your system:
  • Utilize your AVR or amplifier for volume control (When the 'Fixed Volume Output is set on the WiiM Ultra).
  • Control volume through the WiiM Home App, but remember to disable fixed volume output for this option. This is recommended way to control the volume of your system.

CONNECT TO WIIM ULTRA'S AUDIO INPUT
This step is optional. The WiiM Ultra features four distinct audio input interfaces: analog LINE IN, Phono IN, digital optical (TOSLINK) IN, and HDMI ARC.
This versatile device acts as both a preamplifier and a network audio transmitter via Wi-Fi or Ethernet. You can stream analog audio inputs from sources such as CD players, vinyl players, TVs, or computers to other WiiM devices (including Ultra, Amp, Pro Plus, Pro, or Mini), either individually or in multiple combinations.

Scenario 1: Analog Audio Source Input (CD Player, Vinyl Player, or Computer)
Connect your source device to the WiiM Ultra's LINE IN port using a line-in cable. One of two types' cable as the follows might be used, i.e., RCA to RCA or Aux to RCA.
Connect to WiiM Ultra's Line IN port

Connect to CD player, vinyl player, TV or computer
Setting Up WiiM Ultra with Line-In Input

1. Connect the Cable:
   • Insert the line-in cable into the LINE IN port on the back of the WiiM Ultra.
   • Connect the other end to the AUX or LINE OUT port on your audio source (CD player, vinyl player, TV, or computer).
2. Configure in WiiM Home App:
   • Open the WiiM Home app and navigate to the 'Browse' tab.
   • Select 'Select source on device,' then choose 'LINE IN' as your audio source.
3. Create Multiroom Group (Optional):

   • Select the WiiM Ultra linked to your LINE-IN device. o Tap the group button (link icon in a box) in the upper-right corner and select the WiiM devices to transmit audio.
4. Play Music:
   • The music from your connected device will now play across your multiroom music group.

Scenario 2: Setting Up WiiM Ultra with Optical IN or HDMI ARC (TV or PC)

1. Connect the Source Device:
   • Use an optical cable to connect your source device to the WiiM Ultra's Optical IN (TOSLINK) port, or an HDMI cable for HDMI ARC.
2. Configure in WiiM Home App:
   • Follow the same steps as for Line-In, replacing 'Line-In' with 'Optical IN' or 'HDMI.'

Notes:

• Enable Autosense:
  • Automatically play your Line-In, Optical-In, or HDMI source when a signal is detected. Enable this feature in the WiiM Home App.
• Built-in EQ:
  • Adjust audio input to your taste with the built-in EQ. Control audio volume remotely via the app without adjusting the input device.
