The optional RTA-M real time audio analyzing mic is the perfect accessory tool for the DriveRack PA series (PA, PX, PA+, PA2) and 260. Used in conjunction with the System Setup Wizard and Auto EQ Wizard the RTA-M is ideal for optimizing the sound quality of even the most difficult of acoustic environments.

The RTA-M is an omni-directional, flat frequency measurement microphone specially designed for the Driverack series to pick up all frequencies from 20 Hz to 20 kHz , ensuring accurate "pinking"/real-time analysis of your audio. It runs on phantom power (supplied by the Driverack units) and comes with a clip and case.

Recommended for: Studio, Tour, Portable.

What is the differenece between the dbxRTA-M and the M2 microphone (which ships with the DriveRack PX)?

The RTA-M is an accessory, which can be purchased separately. The M2 microphone is not sold separately and ships with the Driverack PX. The M2 microphone uses the same element as the RTA-M, but has a plastic housing where the RTA-M's housing is metal, so the M2 is not quite as rugged as the RTA-M. Also, the RTA-M comes with a hard-cover case. However, the specifications on these two microphones are very similar.

Note: You can use these two microphones interchangably between the different DriveRack models.
