RADAR (Random Access Digital Audio Recorder)[1][2] is a product line of professional digital multitrack recorders capable of recording and playing back twenty-four tracks of audio.


The first model, the Creation RADAR I, was released in 1993. RADAR I was manufactured in North Vancouver BC by Creation Technologies(iZ Technology Corporation), but marketed and distributed in 1994 by Otari under an exclusive license. Creation/iZ also produced the RADAR II. iZ Technology terminated Otari's RADAR distribution agreement in 2000.[3]

In October 2000, iZ Technology released RADAR 24 under the iZ brand, [4] which was based on BeOS 5.[5] In 2005, iZ released RADAR V.[6] In 2012, iZ released RADAR 6 at the October 2012 AES show in San Francisco

Parallel to the development of the various hardware models, there have been many revisions to the RADAR system software.

Hardware Models[edit]

RADAR I[edit]

The RADAR I was the first model released, under the Otari brand in 1994. It was capable of recording and playing back twenty-four tracks of 16 bit, 48k audio.[1] It also was available with 24 Adat I/O Card.

RADAR II[edit]

The Otari RADAR II, released in 1997, was capable of recording and playing back twenty-four tracks of 24 bit, 48k audio on a single hard drive, editing and multiple-machine linking for up to 192 tracks.[2] Until April 2000, the RADAR II was branded as the "Otari RADAR II." After April 2000, it was sold by iZ Technology as the "iZ RADAR II."[7]

RADAR 24[edit]

RADAR 24, released in 2000, was the first new model branded by iZ Technology,[4] and brought many hardware improvements including: sample rates up to 192k, networking, a faster processor, and ADAT I/O.[8]

RADAR V[edit]

RADAR V, released in 2005, added many capabilities to the RADAR 24 including the ability to record on all 24 tracks at high sample rates of 96k and 192k; direct recording to industry-standard Broadcast WAV files; Dual Disk and Span modes for recording to multiple drives; File Flattening options to consolidate audio for handoff; and Gigabit Ethernet file transfer.[9][10] The model name "V" is pronounced "Vee," not "Five."

RADAR 6[edit]

RADAR 6 was released in October 2012, with an entirely new, smaller, lighter and quieter form factor. The new model had a touch-screen interface and tactile transport keys on the front of the unit, and offered new storage options such as solid state drives, USB 3.0 drives and SD cards.[11] At this time iZ also improved their AD/DA converter cards and consolidated to two card choices instead of three.[12]

RADAR studio[edit]

RADAR studio, released in 2015, incorporated a 'Workstation' platform alongside the original RADAR software, allowing industry standard DAWs to be run on the RADAR, using RADAR as the host computer.[13][14]

Software Versions[edit]

As of 2012, two RADAR software systems have been developed for RADAR V and RADAR 24. Software version 4.0 and up is currently under development for the RADAR 6 platform. 3.5x, iZOS, the first version of which was released in July 2008, requires a new system drive and a processor rated at a minimum of 800 MHz, and is no longer being developed. 3.4x is the older BeOS version of the operating system, which is also no longer being developed.[15]
