5. Setup Guide
5.1. Power Supply
The mixer can be powered in several ways:
- **Via Computer USB Port:** Connect the mixer directly to your PC's USB port using the provided USB cable.
- **Via Power Adapter:** Use the included power adapter (DC 5V/2.0A standard) to connect the mixer to a wall outlet.
- **Via Power Bank:** For portable use, connect the mixer to a compatible USB power bank.
5.2. Connecting Audio Devices
Refer to the diagrams below for typical connection setups. The mixers support various audio sources and output devices.
- **Microphones:** Connect XLR microphones to the MIC/LINE inputs. For condenser microphones, activate the 48V PHANTOM power switch (if available on your model and channel).
- **Instruments:** Connect guitars, electronic organs, or other instruments to the MIC/LINE inputs.
- **Playback Devices:** Connect CD players or other audio sources to the LINE inputs. USB drives can be inserted into the USB port for MP3 playback.
- **Computer/Laptop:** Connect the mixer to your computer via USB for use as a sound card for recording or playback.
- **Speakers/Amplifiers:** Connect your main output (MAIN OUT L/R) to a power amplifier and speakers.
- **Headphones:** Connect headphones to the PHONES output for monitoring.
- **Bluetooth:** Activate Bluetooth mode on the mixer and search for it on your electronic device to connect wirelessly for audio input.
6. Operating Instructions
6.1. Basic Controls
- **GAIN Knob:** Adjusts the input sensitivity for each channel. Start with a low setting and gradually increase until the signal is strong without peaking.
- **EQ (Equalization):**
- **HIGH:** Adjusts the treble frequencies (e.g., 10kHz for A6, 12KHz for A4).
- **LOW:** Adjusts the bass frequencies (e.g., 100kHz for A6, 80Hz for A4).
- **PEAK LED:** Illuminates when the signal approaches distortion (typically 3dB below clipping). Adjust GAIN to prevent this.
- **MAIN STEREO LEVEL Knob:** Controls the overall output volume. Green light indicates signal presence (-10dB), red light indicates signal near distortion (3dB below clipping).
- **48V PHANTOM Power:** Activates 48V power for condenser microphones. Ensure it's off when connecting dynamic microphones or other devices that don't require phantom power.
6.2. DSP Effects (A6/A4)
The A6 and A4 models feature 24 types of DSP effects, including various reverbs, electronic mixed sounds, and voice effects. Use the dedicated controls to select and adjust these effects.
- **Reverberation:** Simulates acoustic environments like concert halls, auditoriums, and theaters.
- **Electronic Mixed Sound:** Provides various key-based electronic sound effects.
- **Diacritical Synthesis Sound Effect:** Includes voice modulation effects such as female voice, uncle sound, children's voice, and magic sound.
6.3. USB Audio and MP3 Playback
The mixers are equipped with a USB interface for both audio playback and computer connectivity.
- **MP3 Playback:** Insert a USB drive containing MP3 files into the USB port. Use the display and navigation buttons (UP, DOWN, MODE) to select and play tracks.
- **Computer Sound Card:** Connect the mixer to your computer via USB. The mixer will function as a 2-in/2-out USB 2.0 audio interface, allowing you to record audio from the mixer to your computer and play computer audio through the mixer.
6.4. Bluetooth Connectivity
For wireless audio input, the mixers support Bluetooth connectivity.
- Switch the mixer to Bluetooth mode.
- On your electronic device (smartphone, tablet), search for available Bluetooth devices.
- Select the TEYUN mixer to pair and connect.
- Once connected, you can stream audio wirelessly to the mixer.
7. User Tips
- **Gain Staging:** If experiencing low sound levels, ensure all gain knobs (input, main output) are appropriately adjusted. Avoid setting them too high to prevent distortion (indicated by the PEAK LED).
- **Reverb Effects:** The mixers include built-in reverb and delay effects. Experiment with the DSP settings to find the desired ambiance for vocals or instruments.
- **Recording to PC:** When using the mixer as a sound card, ensure your computer's audio input settings are configured to recognize the mixer. The USB audio function typically records a stereo mix, not individual tracks.
- **Power Options:** For maximum portability, consider using a power bank to power the A4 mixer, especially for outdoor or remote setups.
- **XLR Microphones:** The mixers support XLR microphones, including condenser microphones when 48V phantom power is activated.
- **Versatile Use:** These mixers are well-suited for various applications, including podcasts, live webcasts, home music production, and connecting to a wide range of speakers.
8. Troubleshooting
- **No Sound Output:**
- Check all cable connections (inputs, outputs, power).
- Ensure the mixer is powered on.
- Verify that all relevant GAIN and volume knobs (channel, main, headphone) are turned up.
- Check if any MUTE buttons are active.
- **Low Sound Level:**
- Increase the GAIN for the specific input channel.
- Increase the MAIN STEREO LEVEL.
- Ensure the connected audio source (e.g., microphone, instrument) is producing a strong signal.
- **Distorted Sound (PEAK LED lit):**
- Decrease the GAIN for the input channel that is peaking.
- Lower the volume of the audio source.
- **No Phantom Power for Condenser Mic:**
- Ensure the 48V PHANTOM power switch is engaged for the relevant channel.
- Verify the microphone is correctly connected via an XLR cable.
- **Bluetooth Connection Issues:**
- Ensure the mixer is in Bluetooth pairing mode.
- Check that Bluetooth is enabled on your device and it's within range.
- Try unpairing and re-pairing the device.
- **Noise/Hum when connected to PC:**
- This could be a ground loop issue. Try connecting the PC and mixer to the same power strip.
- Ensure all cables are properly shielded and in good condition.
- Test with a different USB cable or port.
