Behringer Xenyx 1202 FX Power Supply Alternatives: DIY or Compatible Solutions

If you're in need of a replacement power supply for your Behringer Xenyx 1202 FX audio mixer but can't find the original power supply at a reasonable price, there are a few options you might consider. This article explores both DIY solutions and compatible power supplies that can keep your mixer up and running.

Original Power Supply Details

The original power supply for the Behringer Xenyx 1202 FX model is an AC transformer with the following specifications:

Output 1: 2 x 18.5 VAC at 2 x 250 mA Output 2: 3.0 VAC at 100 mA

Output 1 is the long wire with a 3-pin mini-DIN plug, which is actually a 37-volt 250 mA centre-tapped transformer winding, not two independent 18.5 V windings as the specifications might suggest. The output measures around 40 VAC between the two furthest-apart pins of the DIN-3, with about 20 V between the outer pins and the centre pin. This setup allows for a bipolar -25 V output for op amps in the mixer.

DIY Power Supply: A Possible Solution

If you're comfortable with DIY projects, you can create your own power supply for the Behringer Xenyx 1202 FX. Here’s how:

Selecting the Transformer: Choose a transformer that can provide around 36-40 V with a centre tap, capable of handling at least 250 mA at that voltage. If you want to use two independent 18-20 V windings, you can connect them in series to create a single 36-40 V output with a centre tap. Connecting the Transformer: Connect one end of the centre tap and the other end of the secondary winding to the pins of a male DIN-3 connector, ensuring the correct pin configuration. Providing Output 2 (Optional): If you need the additional 3 VAC, you can use a separate small transformer for this output.

This DIY approach gives you a lot of control over the design and can be more cost-effective than finding a replacement power supply.

Compatible Power Supply Solutions

Another option is to use a compatible power supply that matches the requirements of your Xenyx 1202 FX mixer. You can find suitable power supplies on platforms like Amazon or eBay at reasonable prices. Some users have also reported success with smaller Behringer mixers using the same power supply, so you might find a compatible model with the same specification.

For example, the Behringer Q802USB mixer has a similar power supply setup. If you can find a Q802USB power supply, it might be a more direct replacement. Simply use the same connectors as the original power supply and ensure that the output specifications are consistent.

Steps to Replace the Power Supply

Unboxing the Power Supply: Ensure that the new power supply matches the output specifications of your Xenyx 1202 FX. Double-check the voltage and current ratings. Removing the Old Power Supply: Carefully remove the old power supply from the mixer. Disconnect all wires and double-check that they are securely connected. Connecting the New Power Supply: Connect the wires from the new power supply to the corresponding terminals on the mixer. Ensure that the power supply is secured tightly and the connections are safe. Testing the Mixer: Power on the mixer and test all functions to make sure everything is working correctly.

By following these steps, you can ensure that your Behringer Xenyx 1202 FX mixer is back up and running without the need to purchase an expensive, discontinued power supply.

Conclusion

When faced with the challenge of finding a Behringer Xenyx 1202 FX power supply at a normal price, consider both DIY solutions and compatible power supplies. Both options can save you money and ensure your mixer functions properly. For those with the necessary skills and tools, building a DIY power supply is a viable option, while compatible power supplies offer a more straightforward solution.
