Especially notable for a wireless system at this price point is that both the DWZ-M70 and DWZ-B70HL packages have advanced digital signal processing to minimize audio feedback and 128-bit AES data encryption for secure audio transmission.

Ideal and totally flexible for modest installed sound applications, houses of worship, corporate board rooms or night club stages, the DWZ systems have two methods for 2.4GHz frequency selection and the rack-mountable receivers have an integrated color LCD and a built-in digital program EQ. The receivers connect easily using either balanced and unbalanced audio outputs and the handheld mics support both Sony's or any third-party's interchangeable mic capsule.

The DWZ-M50 Vocal Set includes an interchangeable cardioid dynamic microphone capsule for its handheld transmitter and a half-rack size receiver while the DWZ-GB30 Guitar Set goes with a body pack transmitter with guitar cable tone control and compact size receiver powered by an AC adapter, 9V battery or external DC.

The DWZ-M70 Vocal/Speech Set includes an interchangeable cardioid dynamic microphone capsule for its handheld transmitter and half-rack size receiver and the DWZ-B70HL Headset and Lavaliere Set uses either a cardioid condenser headset microphone or uni-directional condenser lavaliere mic, body pack transmitter and receiver with advanced DSP functions.
