Frequently Asked Questions [+]

Where can I obtain the Live Drive app?

The Live Drive iOS app is available from the Apple App Store: Alto Professional Live Drive iOS App

How does the Live Drive iOS app connect to Black series loudspeakers?

The Live Drive iOS app connects to Black series loudspeakers using Bluetooth. The Live Drive app can be run from your Bluetooth-capable iOS device so that you can wirelessly level-match, EQ, time-align, and more. This connection sends control data to the speaker's internal Digital Signal Processor (DSP).

Can I stream music via Bluetooth to my Black series loudspeakers?

The Bluetooth connection is exclusively intended for control and visual signal monitoring from within the Live Drive iOS App. Audio cannot be streamed via Bluetooth to the Black series loudspeakers.

What is the range of the Bluetooth signal?

The typical range is up to 80 feet (25 meters) indoors with a clear line of sight. However, the range may vary depending upon your source device and the environment.

What type of EQ is available on the Black series speakers? How does it work?

Press the DSP button on the rear of the Alto Black series speaker to set the loudspeaker's internal DSP to any of the following settings:

  • Flat: No change to the audio.
  • Contour: Boosted bass and treble with a gradual cut of mid-range frequencies—a useful setting for most contemporary music.
  • 80Hz HP: Applies a high-pass filter. This is useful when using the Black 15 as a crossover with a subwoofer that does not have a high-pass output. This setting is also useful for cutting all bass frequencies (e.g., for in speech-only applications, or when used as a delay or fill loudspeaker where the extra bass frequencies are not needed).
  • Ext LF: Extends the loudspeaker's low-frequency response, providing increased output of bass frequencies.
  • Custom: Applies your custom DSP mode, set in the Live Drive app.

Additional control of the DSP is also available using the Live Drive app.
