Open System for Compatibility The 02R features an "open system" for compatibility with all major industry-standard digital audio formats: TASCAM (TDIF-1), ADAT, AES/EBU, and Yamaha. Optional I/O interfaces allow the 02R to be easily integrated with any digital recorders, whether tape-based, or Non-linear "Hard-disc or Magneto optical." *See Optional Accessories. Versatile 40-Input / 8-Buss Configuration The 02R features 40 input channels (24 analog and 16 digital), 8 output busses (analog/digital), 16 direct outputs, and 8 auxiliary sends for extraordinary signal processing power in remarkably compact dimensions. A single 02R can handle digital mixdown of up to 32-tracks. Individual Channel PEQ and Dynamics All input channels feature independent 4-band parametric equalization and dynamics for module functionality on a par with top-line professional consoles. On-board Automation The 02R offers real-time SMPTE or MIDI time-code based recording and mixdown automation without the need for add-ons or modification. In addition all console settings can be stored in snapshots, for instant re-set of every mix parameter. Twin RISC CPUs and 32-bit Processing Newly developed Yamaha custom 32-bit signal processing LSIs and twin RISC CPUs add up to unprecedented sound quality and response speed. Compatibility with All Major Digital Formats The 02R integrates seamlessly with digital recorders and other equipment using industry-standard digital audio formats. Simply select the appropriate optional I/O interface cards (8 channels per card) and plug them into any of the 4 YGDAI (Yamaha General Digital Audio Interface) slots provided on the rear panel for direct connection to a wide range of Modular Digital Multitrack recorders, Digital Audio Workstation, and other digital equipment. Interfaces Since the interfaces can be selected and purchased as required, you may pay for the interface according to the number of tracks you have. Card types can be mixed. AD/DA interface (8 channels per card) using high-performance 20-bit converters is also available for connection to analog MTRs. 40 Inputs, 8 Busses, 8 Aux Sends The 02R offers extraordinary input/output capacity for its size. 24 analog inputs and 16 digital inputs add up to a total of 40 channel inputs. Channels 1 through 16 16 of the 24 analog inputs feature high-performance head amplifiers for optimum matching with microphone or line sources. Channels 1 through 8 have balanced XLR type connectors (with phantom power) and TRS phone jacks with input A/B switching and insert patch points. Channels 9 through 16 have balanced TRS phone jack inputs. These 16 channels can also be configured for digital inputs (TASCAM, ADAT, YAMAHA format), providing a total of 32 channels for digital mixdown. Channels 17/18 through 23/24 Channels 17/18 through 23/24 accept line-level sources. 16 Digital Input Channels The 16 digital input channels (TAPE 1 to 16) accept digital input in TASCAM (TDIF-1), ADAT, or any YAMAHA digital audio format. With the addition of an optional AD/DA interface the output from analog MTRs can also be returned to these channels for full 40-channel analog input capability. 8 Auxiliary Sends 8 auxiliary sends provide versatile signal-routing capability. AUX 5 and 6 can be used individually or as a stereo control room or studio monitor send, or as a performer's cue mix send when recording. AUX 7 and 8 feed internal high-performance digital effect processors, and can be series-connected for sophisticated effect capability. The sends for each channel can be switched for pre- or post-fader operation, while 1/2, 3/4 and 5/6 can be used as stereo sends if required. Two Pairs of Analog 2-track Inputs Two pairs of analog 2-tract inputs (balanced TRS phone and unbalanced RCA pin jacks) and 3 stereo digital 2-track inputs (one AES/EBU and two COAXIAL S/P DIF inputs) are provided. Two of the digital inputs can be routed to stereo input channels 17/18 and 19/20 for recording or mastering applications. Multiple consoles can be cascaded for increased input capacity. Two 02R consoles, for example, can be connected to provide up to full-featured 80 inputs on 64 track digital mixdown. Full Processing On All Inputs The 02R provides extensive digital signal processing capabilities on all 40 channel inputs and 2 stereo effect returns for total creative control. Precise response tailoring is easy with 4-band full parametric equalization on all inputs: analog inputs 1 through 24, digital tape inputs 1 thrugh 16,and stereo effect returns 1 and 2. The LOW and HIGH bands can be used in shelving or HPF/LPF filters as required. A graphic display on the console's large LCD provides instantaneous visual feedback. Dynamics Processing Dynamics processing is also provided on all 40 input channels. 5 processor types are individually selectable for each channel: compressor, gate, ducking, expander, and a combined compressor/limiter/expander. Key-in and stereo link functions are also provided. Individual processing on each channel offers the type of extensive dynamics control previously only associated with much larger, extremely expensive high-end consoles. Other Important Channel Controls Include 20 dB pad switches on channels 1 through 16, detented trim controls (-16 to -60 dB on channels 1 through 16; +4 to -40 dB on channel 17 through 24), peak/signal indicators, phase switches, programmable channel delay up to 60 milliseconds, and direct outputs on channels 1 through 16. EQ, Dynamics and Effect Settings EQ, dynamics and effect settings can all be saved in memory for instant recall whenever needed. A large user memory area is provided in addition to a powerful preset library. These settings can also be handled as events within an automation program. An "undo" function instantly recalls the settings prior to a save operation, making it easy to try out new settings without losing all previous data. Up To 4 Fader Groups Up to 4 fader groups in which a single fader controls multiple specified faders, and 4 mute groups, can be set up as required. This allows convenient control of multi-source "sections" for significantly enhanced operation ease and efficiency. For convenient handling of stereo signals, the EQ and other channels parameters of adjacent channels (MIC/LINE 1 to 16, TAPE 1 to 6), can be linked for simultaneous control. Panning can be independent or linked, as required. "Virtual Control Section" In order to make control of a large number of channels with multiple module functions as easy and straightforward as on a traditional analog console, the 02R features a "virtual control section" and large 320 x 240 pixel backlit LCD panel. Routing, auxiliary send level, pan and EQ can all be accessed and adjusted with "analog ease". The appropriate display is automatically selected the instant any function is used for seamless operational efficiency. View Function and Channel Library Function A "view" function simultaneously displays all parameters for the selected channel. There's also a "channel library" function which allows all settings for a single channel to be saved and recalled as required. Data can also be copied from a source channel to any other specified channel. 100 mm Motor Faders 21 x 100-millimeter motor faders offer exceptionally smooth operation and precise control. Extra fader versatility is provided by FLIP keys which can be used to interchange the functions of the linear faders and rotary encoders on channels 1 through 16 for MIC/LINE or TAPE level control. Comprehensive Outputs and Monitor Functions The 02R supports both COAXIAL (S/P DIF) and AES/EBU digital stereo outputs. Balanced XLR type and unbalanced RCA pin-jack analog stereo outputs are also provided. Full 4-band parametric EQ is included in the stereo output stage for even further creative control. Dynamics processing is available on the 8 buss outputs as well as the stereo outputs. Both individual track processing and overall compression can be applied as required to satisfy any recording situation. Monitor Section with Studio and Control Room Monitor Outputs The 02R features a fully-equipped monitor section with studio and control room monitor outputs, each with individual level control. In addition to the 2-track inputs and stereo buss, auxiliary sends 5 and 6 can be used to create a performer's cue mix. Solo Signal: Recording Solo and Mixdown Solo The 02R solo signal is sent to only the control room monitor outputs in the recording solo mode, and to the main outputs in the mixdown solo mode.The solo signal can be taken either pre-fader or post-pan, as required. Summing Solo, Last Solo and In addition to the Summing Solo, a "Last Solo" mode is provided in which only the last pressed solo switch signal is monitored. In the mixdown solo mode a solo-safe function is available for all input channels, allowing monitoring of soloed channel plus associated effects. Built-In Oscillator A built-in oscillator provides 100 Hz, 1 kHz, and 10 kHz sine wave output as well as white noise. The oscillator can be routed to the 8 buss outputs, the stereo outputs, and/or the 8 auxiliary outputs. Time-Code Based Full Automation The 02R allows full automation of all faders (including the AUX send faders) as well as all mixing parameters without the need for add-ons or modification. Recording and mixdown automation can be synchronized to external SMPTE timecode (30f, 30df, 25f, 24f) or MIDI timecode. Dynamic Real-Time Automation Is available for the faders, channel on/off switching, panning, and EQ. Two on-line editing modes are provided: the "absolute" mode in which the written fader data corresponds precisely to the fader positions, and the "relative" mode in which previously written data can be trimmed as required (A "motor off" function stops fader movement for easy control in the relative mode). Snap-Shots 64 scene memories can be used to store "snap-shots" of all cosole fader and parameter settings, and these scenes can also be handled as events for automation. Off-line editing allows scene memory, EQ, effect, and channel library recall to be specified in precise frame increments. A fader recall safe function makes it possible to specify the faders which will be available for unaffected by snapshot recall, leaving them uninterrupted for real-time automation on manual control. Memory 512 kilobytes of automation memory is supplied as standard equipment. Up to two optional 1-megabyte expansion cards can be added as required (2.5 megabytes maximum). External MIDI or Direct Computer Control The 02R is equipped with MIDI IN, OUT, THRU and MTC IN terminals. MIDI program change numbers can be used to simultaneously switch 02R scene memories and programs on external effect devices, while system exclusive data can be used for precise sequence control of all mixing parameters. A "TO HOST" RS422 port is also provided to allow direct control from a personal computer running appropriate software. Precision 20-Bit AD/DA Converters All analog inputs employ high-precision, high-resolution 20-bit linear AD converters with 64x over sampling. The stereo and control-room monitor outputs feature 20-bit linear DA converters with 8x oversampling. Dynamic range at the stereo outputs is a very impressive 110 dB. 105 dB from the MIC/LINE inputs to the STEREO OUT connectors. This type of performance is what digital recording is all about.

Stupidest things you have ever heard during a session

...take him a few mins but he will be right back. Several mins later, he comes back carrying a Yamaha 02R, while his friend is carrying 4 or 5 rack pieces.... I notice this, so I tell them to set all this stuff in the studio, and I ask if there is any more to...

going through the D/A to A/D of the HEDD, lost 6 db of level

...once all your gear is properly calibrated, you can safely monitor the metering of just one of the devices (02R?), but keeping eye on the device with the lowest headroom, just in case (proper gajnstaging).
