Rehearsal: Connecting a Phone or Laptop via AUX

🎒 What to bring

To connect your phone or laptop to the mixer, bring an RCA-to-3.5mm cable (AUX cable) to your session.

• Lite rooms with the Allen & Heath ZED-6FX mixer: you'll need a 2TS-to-3.5mm cable instead.
• iPhone users: you'll also need a Lightning-to-3.5mm adaptor to connect the AUX cable.

⚠️ Please note

• While we try to provide AUX cables where possible, we can't guarantee availability on the day and can't provide spares. If you need this cable, bring your own.
• Bluetooth connection to the mixer or speakers isn't possible — the only way to connect a phone is via the AUX cable method.

🎚️ If the mixer is an Alto Live 1202

1. Make sure the mixer is switched on and the blue power light is lit. Check its power cable is properly plugged in.

2. Make sure the speakers are on and showing the power light. Check their power cable is properly plugged in and they're switched on at the wall sockets.

3. Using the RCA-3.5mm jack (AUX) cable, plug your device into the "2Track IN" port at the back of the mixer.

4. On your laptop's audio settings, make sure the Output device is set to "Built-In Output" or "External Audio/Headphones".

5. Below the FX section, look for the "2Track IN" blue knob. 
Make sure the button next to it is unpressed (set to "Main Out") and the blue knob is turned up to a reasonable level while playing audio.

6. Turn up the MAIN slider on the mixer — the last slider on the right. Set it to a reasonable level, about ¾ of the way up.

Your device is now ready to play through the speakers.

🔧 Common fixes if it's still not working (Alto Live 1202)

• Make sure the RCA (red and white/black) cables are connected into the "2 Track IN" inputs, not "2 Track OUT" — if connected to OUT, you'll get very quiet playback.
• Double-check the "2 Track In" button is set to the MAIN OUT position (not pressed in).

🎚️ If the mixer is a Proel MQ12USB

1. Repeat steps 1 and 2 from the Alto Live 1202 section above (mixer and speakers power check).

2. Using the AUX cable, plug your device into Channel 9/10 or 11/12's red and white sockets. On 11/12, make sure the grey button is unpressed (set to "Line").

3. On your laptop's audio settings, make sure the Output device is set to "Built-In Output" or "External Audio/Headphones".

4. Turn up the grey Volume slider at the bottom of the channel while playing audio from your device.

5. Turn up the Main Mix slider on the mixer — the last one on the right.

Your device is ready to play through the speakers.

🎚️ If the mixer is an Allen & Heath ZED-6FX

1. Repeat steps 1 and 2 from the Alto Live 1202 section above (mixer and speakers power check).

2. Prepare your 2TS to 3.5mm cable (also called a double large jack to small jack AUX cable). We don't provide extra cables — bring this one from home.

3. Connect the small jack end into your device and the 2 large jacks into ports L and R of Channel 4 on the mixer. Turn up the volume knob at the bottom, making sure the headphones button is unpressed. Turn up the MAIN MIX fader — music should now be playing.

🎚️ If the mixer is an Alto 802 Live

1. Repeat steps 1–3 from the Allen & Heath ZED-6FX section above, including preparing the 2TS to 3.5mm cable.

2. Connect the small jack end into your device and the 2 large jacks into ports L and R of Channel 5/6 on the mixer. Turn up the volume fader at the bottom of the channel and the MAIN MIX fader — music should now be playing.

🎚️ If the mixer is a K-MixerPro 8 Channel

1. If connecting with an AUX cable, plug into the red and white IN sockets near the top right of the mixer.

2. Alternatively, you can connect via Bluetooth or a USB stick.
