Recording Studio (From CCRMA Recording Studio User's Guide)
The recording studio consists of a control room and an adjoining recording studio. Equipment available currently includes three Tascam DTRS 8-track digital recorders, an Ampex ATR-104 analog 1/2" 4-track recorder (with dbx and/or Dolby A), an Ampex ATR-800 analog 1/4" stereo recorder, a ProTools HD system, a Mackie Digital Eight Bus (D8B) mixing console, an Apogee Big Ben word clock system, a Presonus M80 eight-channel mic preamp, a Waves L2 Ultramaximizer digital limiter, a Panasonic SV-3800 DAT recorder, a Tascam CD-RW700 CD-R/RW recorder, a Lexicon 224XL digital reverberator, an Eventide Orville effects processor, Westlake BBSM-10 and JBL 4206 monitors, and outboard gear including equalizers, compressors (including Teletronix LA-2A and Universal Audio 1176), and other digital effects processors. All digital recorders and the mixer are synchronized to word clock from the Big Ben. All analog equipment in the control room is connected through a patch bay, and all connections are to be made through the patchbay: NEVER DISCONNECT ANY AUDIO CONNECTIONS IN THE RECORDING STUDIO. A Linux PC-based computer system is also available in the control room.

Microphones available in the recording studio include a Neumann TLM-193, two AKG C414B-ULSs, two Audio-Technica AT4049 omni condensor mics, 2 Josephson C42 cardioid condensor mics, a Beyer M-500, a Sennheiser MD-421, two Sennheiser E-604s, two Electrovoice RE-20s, an Electrovoice N/D868, two Shure Beta-57s, and several Shure SM-57s. Microphones are stored in the file cabinet in the control room closet; condensor mics in the top drawer and dynamics in the second drawer. There is a Yamaha C7 Disklavier MIDI grand piano in the studio. Two snakes connect microphone inputs to the console: one connects directly to the 12 Mackie mic inputs and the second connects to the Presonus mic preamp system. Channel 15 of the first snake sends headphone signals to the studio for monitoring. A talkback system operates between the control room and the recording studio, located on a panel in the patchbay rack. The talk switch is off in the center position and on in either the locking (up) or momentary (down) positions.

Equipments
2 x Audio-Technica AT4049, made in Japan
2 x AKG C414B-ULS, made in Australia
Mackie Digital Eight Bus (D8B) mixer
Pro Tools 6.9 / Max OS X 10.3

Mic Position
Goal is to capture clear piano sound without any effects, such as room reverberation, echo, etc., while too much hammer noise is not preferred. So I put two AKG-414 from a far field with the lib wide open, height is about 20” higher than the keyboard. And two AT4049 were placed inside the piano, position is approximately at 1/3 and 2/3 of the whole keyboard width. The height of the AT4049 is about 10” from the string.


Pro Tools
4 tracks (48,000Hz, 24Bits) are panned to mono separately and export to wav format file.
