Choosing the Right Location

Choosing the right location for your speakers is crucial for optimal sound quality. Here are some tips to consider:

• Height and Positioning: Place the speakers at ear level when you’re seated in your primary listening position. This ensures that the sound waves reach your ears directly.
• Distance: Keep the speakers equidistant from each other and from your listening position to create a balanced stereo image.
• Surface: Use a stable surface to avoid vibrations that could affect sound quality. Consider using isolation pads to minimize surface resonance.

Connecting the Audioengine A2+ Speakers

Step 1: Connecting the Speakers

1. Place the Speakers: Position the left and right speakers in your desired locations. The left speaker is the powered speaker with the amplifier.
2. Connect the Speaker Wire: Use the provided speaker wire to connect the left speaker to the right speaker. Insert one end of the wire into the left speaker’s output terminals and the other end into the right speaker’s input terminals. Ensure the polarity (+ and -) is consistent on both ends.

Step 2: Powering Up

1. Connect the Power Supply: Plug the power supply into the left speaker’s power input.
2. Plug Into an Outlet: Connect the power cable to an electrical outlet. The left speaker will power on, and you should see a power indicator light up.

Step 3: Connecting Your Audio Source

The Audioengine A2+ offers multiple connectivity options. Choose the one that best suits your setup.

Option 1: USB Connection

1. Connect the USB Cable: Plug one end of the USB cable into the USB input on the back of the left speaker.
2. Connect to Computer: Plug the other end into a USB port on your computer.
3. Select the Audio Output: On your computer, go to the sound settings and select “Audioengine A2+” as the output device.

Option 2: 3.5mm Audio Cable

1. Connect the 3.5mm Cable: Plug one end of the 3.5mm audio cable into the input on the back of the left speaker.
2. Connect to Audio Source: Plug the other end into the headphone jack or audio output of your device (e.g., computer, smartphone, tablet).
3. Select the Audio Output: If necessary, go to your device’s sound settings and select the appropriate output.

Option 3: RCA Connection

1. Connect the RCA Cables: Plug the RCA cables into the RCA inputs on the back of the left speaker (red to red, white to white).
2. Connect to Audio Source: Plug the other end of the RCA cables into the RCA outputs of your audio source (e.g., turntable, TV).
3. Select the Audio Output: If necessary, go to your device’s sound settings and select the appropriate output.

Step 4: Adjusting Volume

The left speaker has a volume control knob. Start by setting it to a moderate level, and then adjust the volume on your audio source. Fine-tune the volume on the speaker for optimal listening.

Optimizing Sound Quality

Speaker Placement

Proper speaker placement can significantly impact sound quality. Here are a few tips:

• Distance from Walls: Position the speakers at least a few inches away from walls to reduce bass buildup and reflections.
• Toe-In: Angle the speakers slightly towards your listening position. This can help create a more focused stereo image.
• Subwoofer Integration: If you’re using a subwoofer, ensure it’s properly integrated with the speakers. Experiment with placement and crossover settings to achieve a seamless blend between the subwoofer and the A2+ speakers.

Acoustic Treatment

Consider adding some acoustic treatment to your listening area to further enhance sound quality:

• Absorption Panels: Place absorption panels on walls to reduce reflections and echo.
• Bass Traps: Use bass traps in the corners of the room to control low-frequency buildup.
• Diffusers: Add diffusers to scatter sound waves and create a more natural listening environment.

Equalization and DSP

Some audio sources and playback devices offer equalization (EQ) and digital signal processing (DSP) options. Use these features to fine-tune the sound to your preference. For instance, you might want to boost the bass or treble slightly to match your room acoustics and personal taste.

Troubleshooting Common Issues

Even with careful setup, you may encounter some common issues. Here’s how to address them:

No Sound

• Check Connections: Ensure all cables are securely connected and the power supply is plugged in.
• Select the Correct Output: Verify that your audio source is set to output sound to the Audioengine A2+ speakers.
• Volume Levels: Make sure the volume on both the speakers and the audio source is turned up.

Distorted Sound

• Reduce Volume: Lower the volume on both the speakers and the audio source to see if distortion persists.
• Check Cables: Ensure the cables are not damaged or improperly connected.
• Source Quality: Verify that the audio source is of good quality. Low-bitrate files can sound distorted.

Uneven Sound

• Check Speaker Placement: Ensure the speakers are equidistant from your listening position and properly angled.
• Balance Settings: Check the balance settings on your audio source to ensure it’s centered.

Interference and Noise

• Reduce Interference: Keep the speakers and cables away from sources of electromagnetic interference (e.g., routers, other electronics).
• Ground Loops: If you hear a hum or buzz, you may have a ground loop issue. Use a ground loop isolator or try plugging the power supply into a different outlet.

Advanced Setup Options

Using a Subwoofer

Adding a subwoofer can enhance the low-frequency performance of your Audioengine A2+ speakers. Here’s how to integrate a subwoofer:

1. Connect the Subwoofer: Use an RCA cable to connect the subwoofer’s input to the RCA output of your audio source or the preamp output of the A2+ speakers.
2. Adjust Crossover: Set the subwoofer’s crossover frequency to match the A2+ speakers. Typically, this is around 80Hz.
3. Positioning: Place the subwoofer in a location where it blends seamlessly with the A2+ speakers. Experiment with different positions to find the best sound.

Using an External DAC

An external digital-to-analog converter (DAC) can further improve sound quality by providing a cleaner signal. Here’s how to set up an external DAC with the A2+ speakers:

1. Connect the DAC: Use a USB or optical cable to connect the DAC to your audio source.
2. Connect to Speakers: Use an RCA cable to connect the DAC’s output to the RCA input on the left speaker.
3. Select the DAC: Ensure your audio source is set to output sound through the external DAC.

Wireless Streaming

While the Audioengine A2+ does not have built-in Bluetooth, you can add wireless streaming capability with an external Bluetooth adapter:

1. Connect the Adapter: Plug the Bluetooth adapter into the 3.5mm or RCA input on the left speaker.
2. Pair Your Device: Follow the adapter’s instructions to pair it with your smartphone, tablet, or computer.
3. Select the Adapter: Set your audio source to output sound to the Bluetooth adapter.

Maintenance and Care

To keep your Audioengine A2+ speakers in top condition, follow these maintenance tips:

Regular Cleaning

• Dusting: Use a soft, dry cloth to dust the speakers regularly. Avoid using abrasive materials that could scratch the surface.
• Cleaning Grilles: If the speaker grilles are removable, gently remove and clean them with a soft brush or vacuum with a brush attachment.

Protecting from Damage

• Avoid Overdriving: Don’t play the speakers at excessively high volumes for extended periods, as this can cause damage.
• Keep Dry: Ensure the speakers are kept away from moisture and direct sunlight.
• Handle with Care: When moving the speakers, handle them gently to avoid damaging the internal components.

Software and Firmware Updates

While the Audioengine A2+ speakers themselves do not have firmware or software that needs updating, the devices you connect to them might. Keeping your audio source devices updated ensures optimal compatibility and performance. For instance:

• Computer Updates: Ensure your computer’s operating system, audio drivers, and music playback software are up to date.
• Streaming Devices: If using a streaming device, check for firmware updates to maintain compatibility and performance.
• Bluetooth Adapters: If using an external Bluetooth adapter, periodically check for firmware updates from the manufacturer to ensure the best possible wireless performance.

Periodic Checks
