Configuració

Follow these steps to set up your Nobsound G2 PRO ampmés viu.

1. Connexió d'alimentació:

1. Assegureu-vos el ampL'interruptor ON/OFF del lifiler està en la posició OFF.
2. Connect the provided 32V 5A power supply to the DC24V-48V input on the rear panel of the ampmés viu.
3. Connecteu la font d'alimentació a una presa de corrent adequada.

2. Audio Input Connection:

Connect your audio source (e.g., smartphone, computer, CD player) to the AUDIO IN RCA ports on the rear panel using appropriate RCA cables.

3. Speaker Output Connection:

The G2 PRO can be configured for different speaker setups:

3.1. 2.0 Channel Setup (Using two G2 PRO units for stereo):

For a stereo setup, two Nobsound G2 PRO units are required. Each unit will drive one channel (left or right) independently, minimizing mutual interference.

Figure 7: 2.0 Channel Stereo Setup Diagram.

1. Connect the left channel output from your audio source to the AUDIO IN of the first G2 PRO unit.
2. Connect the right channel output from your audio source to the AUDIO IN of the second G2 PRO unit.
3. Connect your left passive speaker to the SPEAKER OUT terminals of the first G2 PRO unit.
4. Connect your right passive speaker to the SPEAKER OUT terminals of the second G2 PRO unit.
5. Ensure both G2 PRO units are set to PBTL (full-frequency) mode using the front panel switch.

3.2. 2.1 Channel Setup (with active or passive subwoofer):

The G2 PRO can be integrated into a 2.1 channel system. The diagram below illustrates two common methods.

Figure 8: 2.1 Channel Setup Diagrams (Way 1 & Way 2).

• Way 1: Using one G2 PRO for full-frequency speakers and SUB output for active subwoofer.
  1. Connect your audio source to the AUDIO IN of the G2 PRO.
  2. Connect your passive full-range speakers to the SPEAKER OUT terminals of the G2 PRO.
  3. Connect the SUB OUT of the G2 PRO to the input of your active subwoofer.
  4. Set the G2 PRO to PBTL (full-frequency) mode. The SUB output will still function.
• Way 2: Using multiple G2 PRO units for full-frequency and passive subwoofer.

  This setup requires an audio switcher/splitter with multiple outputs or a DIY audio input cable to split the signal.

  1. Connect your audio source to an audio switcher/splitter.
  2. Connect the split audio signals to the AUDIO IN of two G2 PRO units for left/right full-range speakers (set to PBTL mode).
  3. Connect another split audio signal to the AUDIO IN of a third G2 PRO unit for the passive subwoofer (set to SUB mode).
  4. Connect the respective passive speakers/subwoofer to the SPEAKER OUT terminals of each G2 PRO unit.

4. Ajust de guany:

The G2 PRO has gain setting DIP switches on its bottom panel. Adjust these switches (SW1 and SW2) to select between 32dB and 36dB gain settings based on your audio source's output level and desired volume.

Refer to the "Gain Setting Table" in the "Product Overview" section for switch configurations.

Instruccions de funcionament

Once all connections are made, you can begin operating your Nobsound G2 PRO ampmés viu.

1. Encendre/apagar:

Flip the ON/OFF switch on the front panel to the "ON" position to power on the amplifier. The power light will illuminate. Flip it to "OFF" to power down.

2. Selecció del mode de funcionament:

Use the PBTL/SUB switch on the front panel to select the desired operating mode:

• PBTL (Full-Frequency) Mode: For driving full-range passive speakers. The amplifier will output the full audio spectrum.
• SUB (Subwoofer) Mode: For driving passive subwoofers. The amplifier will apply a low-pass filter, allowing only low frequencies to pass through.

Note: The dedicated SUB OUT RCA port for active subwoofers functions regardless of the PBTL/SUB switch setting, allowing simultaneous output of SUB signal and ampàudio lificat.

3. Control de volum:

Rotate the VOLUME knob clockwise to increase the volume and counter-clockwise to decrease it. Start with a low volume and gradually increase it to a comfortable listening level.

4. Subwoofer Frequency Adjustment (SUB Mode only):

Quan el amplifier is in SUB mode, use the SUB FREQ knob to adjust the crossover frequency for the subwoofer. This allows you to fine-tune the bass response and seamlessly integrate your subwoofer with your main speakers.
