Control and Interface Description

Bluetooth Audio control

• The 4 zones of CL-4 share the same Bluetooth audio input, and the controls related to Bluetooth audio are displayed on the CL-4 Tool public area interface. As shown below：
• The display status area shows the Bluetooth working status: “pairing”, “connected”, and “playing”.
• While Bluetooth is working, you can control and click the previous song, play, pause, and next song.
• The  “Enter pairing” button can disconnect the current Bluetooth connection and re-pair Bluetooth.

Microphone Audio Control

• The 4 partitions share the microphone audio input, and the microphone-related parameter settings are displayed on the CL-4 Tool common area interface. As shown below:
• Microphone 1/ Microphone 2: Shows the microphone connection status.
• Mic pairing: Control the microphone receiving module to enter the pairing state
• Reset button: will reset the microphone configuration parameters to the factory default state
• Volume: Microphone input volume level, range 0~32
• Bass: Microphone audio Bass level, range -5~5
• Treble: Microphone audio Treble level, range -5~5
• Reverb: Microphone audio percentage of reverberation output、Damping、density of reverb tail、decay of reverb tail、the ratio of wet (reverberated) signal to the mixed output, and other parameters to adjust; the level range is 0~32
• Echo: Adjust the attenuation value of the microphone audio echo, the level range is 0~32, the lower the level, the greater the attenuation value, until there is no echo
• Delay: Adjust the interval between microphone echoes. It is valid when ECHO is turned on. The level ranges from 0 to 10. The higher the level, the longer the echo delay time

Public Mute Control

• In the public display interface area, the audio output of all zones can be muted, and the microphone audio can be muted.

Zones overview and basic control

• In the display interface of the public area, you can see the audio source, volume level, and mute status of each zone. Can also click the corresponding button to adjust the volume, mute the audio, or mute the microphone the certain zones alone; the mute status will stay on the interface. Details as shown below：

Zones’ information display and modification

• In the zone’s display interface, its name, firmware version number, and LAN IP address, network module firmware version number, and network module MAC addresses are shown; The “Refresh” button can refresh the displayed content, and the “Modify device name” can modify the zone’s name, after modification, the network module will automatically restart to take it works.

Zone audio Source display and switching

• The audio source of each zone includes BLUETOOTH, RCA IN, HDMI, OPTICAL, COAXIAL as the public functions, and the independent components of each zone: LAN, LINE IN, OPTICAL, USB. You can click to select the audio source of this area, and the audio source icon will be shown on it. When the audio source is playing, the audio output area shown “Playing”, but when there is no audio signal playing, the audio output area shows “Pause”.

Zone audio output adjustment

• In the audio adjustment area of each zone, you can adjust its: audio output volume, BASS level, and TREBLE level. Which is shown as below:
• Volume: Source audio output volume level, range 0~32

When clicked “Mute L” or “Mute R” buttons are clicked, the power output of the left Channel or right Channel can be muted, respectively, andthe button will turn red to indicate it, as shown below:

Zone restore factory settings operation
Click the “Factory Reset” button of the zone to restore the factory settings of its following parameters：

1. Reset the output audio volume level to 10/32
2. Reset the output audio BASS and TREBLE levels to 0
3. Reset custom SSID
4. Reset EQ to Flat

EQModulation interface operation

• Each zone’s interface supports the EQ of the modulated audio output, but only supports up to 10 EQ filters. The modulated EQ curve is displayed on the graphical interface in real time. And its EQ graphical interface is shown below：

The parameter editor has the following features：

1. Support mouse drag and wheel to set filter parameters
2. Support direct input of filter parameters
3. Support EQ parameter configuration export, save, and import application
4. Support the operation of synchronizing the EQ parameters of this zone with other zones
   • When designing EQ, you can add or delete filters by clicking the f0~f9 option boxes. The filter type is selected through the drop-down box. Filter parameters (center frequency f0, gain, Q) can be edited directly or by dragging the mouse or scroll wheel. The editable range of f0 is 20Hz~24KHz, and the editable range of gain is 12dB~+12dB. Note that the value of f0 cannot be set too small, otherwise the IIR filter is prone to distortion, and the gain cannot be set too large, which will easily cause data saturation.
   • In the parameter editor interface, Pre Gain adjustment is supportedranging from -10db to +3db.

In the EQ parameter editor interface, the functions of each button are described as follows：

• • Reset： Reset the EQ curve to Flat
  • Read： Read the EQ in the real-time application of the device
  • Sync： Synchronize the EQ parameters of the current zone with other zones and apply
  • Save： Save EQ parameters to a local folder
  • Apply： Apply EQ parameters to devices
  • Lo ad： Load the locally saved EQ parameters, click Apply after loading to take its effect

EQ preset interface operation

• Each partition page supports the selection of preset EQ, and the preset EQ interface has multiple preset options.

The preset EQ graphical interface is shown in the following figure:

In the EQ parameter editor interface, the function descriptions of each button are as follows:
