Break-in period

Your speakers will sound great out of the box and will get better over time. No need to do anything else but listen to them, however, we do recommend that you give them at least 40 to 50 hours break-in time before doing any critical listening.

Cleaning

We don’t recommend using any solvents or cleaners. Just wipe down the cabinets with a soft, dry cloth.

Other features

Variable audio output

The A2+ Wireless Powered Speakers include a variable full-range preamp audio output so you can connect a subwoofer. You can also stream music to other systems around your house by using our W3 wireless adapters. This output is adjustable so the volume level of this output can be controlled from the A2+ volume control.

Speaker placement

Although your A2+ Wireless speakers are very forgiving with regards to where you place them, it’s true that proper speaker location can have an impact on sound quality. Even though there are different theories on correct speaker placement, rooms and tastes are different so it’s difficult to recommend a perfect setup. We do suggest you feel free to experiment to see what works for you.

As a general rule of thumb for the best soundstage and imaging, tweeters should be at about eye-level in your most frequent listening location. For the best bass response we recommend at least 6 inches of clearance between the rear of the speakers and the wall behind them.

Here are a few more suggestions, assuming you have some flexibility regarding where you place your speakers. No need for concern if your listening space dictates the speakers’ position.

Both speakers should be equal distance from your primary listening position.

Placing the speakers at least 6 feet (l.8m) apart usually provides the best imaging.

Allow at least 6 inches of clearance between the rear of the speakers and the wall or surface behind them.

If you need to turn the speakers on their sides, position the tweeters toward the outside.

If used on a desktop for computer or multimedia speakers, the more solid the surface the better.

A2+ Wireless Troubleshooting Tips

The following troubleshooting tips can help diagnose and correct most concerns with the A2+ Wireless. We have attempted to make this list as comprehensive as possible, so some of these may not apply to your issue, but please go through each tip.

If the power indicator on the A2+ external power supply unit is not illuminated, try these tips:

Make sure the AC power cord is connected to the power supply unit and to a working AC power outlet.
Check that the cable at the other end of the power supply is correctly connected to the rear panel of the left speaker.

If the power supply light is on but you are experiencing an audio-related issue with a wired connection, try these tips:

Verify that the volume/power control on the rear panel is not turned all the way down or powered off (we recommend setting the volume to at least the 10 o’clock position)
Check that the volume level of your audio source components or devices is not set to minimum volume or powered off.
Check speaker wire connections from the left (powered) speaker to the right (passive) speaker. Confirm this by removing the speaker wire from on each speaker and reconnecting. Also check the speaker wire polarity by verifying that the wires are going to same terminals on both speakers.
Check that the cables from your audio sources to the speakers are properly connected. Confirm this by unplugging the audio cables and then reconnecting.
Decrease the volume of the input audio source and increase the volume of the speakers.
Try using different audio input sources and/or devices to see if the problem follows.
Try swapping your left and right speaker via the RCA left and right inputs to see if the issue remains in the same channel or follows the speaker.
If you are using a computer with your A2+ Wireless, make sure the volume is up on your media players, internet radio, master control, device volume, etc. and the balance control is centered.

If your input source has its own EQ, please make sure the low end is at a moderate level, as having too much bass can cause distortion.

If you are using a wireless adapter, preamp, or external DAC with these speakers, remove them (temporarily) and connect the audio input source directly to the speakers.
Move your speakers to a different location to see if something is causing interference in the current setup. Something as simple as a wireless internet router, cordless or mobile phone, or halogen lamp near the speakers can cause interference.

A2+ Wireless troubleshooting tips – internal USB digital-to-analog converter

Try these tips if your computer is not recognizing the speaker through your computer’s USB input or the sound through USB isn’t functioning correctly.

If you are using a Windows computer, uninstall the USB driver from your computer. Then disconnect the USB cable to remove the A2+ from your computer and plug it back in to allow the USB driver to re-install automatically. You can find complete instructions from Microsoft on how to reinstall a plug-and- play device under Windows here.

If you are using a Mac, try a NVRAM/PRAM reset. This resets the system configurations for some audio and video related items and can many times help clear up problems related to audio. See Apple’s support page for information on how to do this.

A2+ Wireless troubleshooting tips – Bluetooth

Verify that the A2+ is connected to power and that the front volume knob is turned clockwise past the detent position (you should feel a click). If you haven’t already, power-cycle your speakers by switching them off and back on.
If your A2+ is already connected to a device via Bluetooth, the Bluetooth pair light on the back panel of the left speaker will be on and solid (note that if your A2+ has been idle and not connected to a device for more than 2 minutes, the Pair light will automatically turn off). Tap the Pair button and it should begin blinking (or pair to your A2+ using your source device, and the LED will go from off to on and solid).
Try playing audio from more than one application on your phone/tablet, or computer.
Check to make sure your source device (computer, tablet, phone, etc) is running the most up-to-date version of software available. For Mac OS users, be sure to check the App store to see if there’s a newer version of Mac OS you could be running.
Try disconnecting from and forgetting the A2+ through your device’s Bluetooth settings, and re-pairing to the A2+.
Try using a different source device with your A2+ to see if the issue follows. Also be sure to test your A2+ using the analog input as well.
If possible, try your A2+ in a different location to see if something is causing an issue in the current setup. Something as simple as a wireless internet router, cordless or mobile phone, or halogen lamp near the speakers may be causing interference in your setup.
