Sound engineer's monitoring and HiFi + HT system with active Yamaha NS-1000x, multi-subs and FIR QSys processor in a particular and treated room
I am Igor Kirkwood, a French sound engineer, recording classical music with minimalistic techniques, natural acoustics, high quality microphones (mostly Neumann TLM 50), no DSP process in recording and mixing. I have also worked for the french hifi magazine DIAPASON, mainly reviewing loudspeakers.
A 10 years strong partnership with Jean-Luc Ohl for technical setup, programming and measurements, helped me to install an uncommon high-end monitoring system.
Some of my recordings
* Arvo Part, Deer's Cry, ECM records
* Music of "Ridicule", a movie of Patrice Leconte on DECCA label, recorded in 5.1 with a DECCA tree.
*The well known CHRISTUS REX soloist Herve Lamy, Jade/Universal
*Bach’ s integral DDD of the organist André Isoir, edited by CALLIOPE, re-edited by LA DOLCE VOLTA
*Bartok, Music for piano strings percussion and celesta, with the Saint Petersburg Orchestra, CALLIOPE
Audio system
For my work (editing and mastering) but also for my pleasure, I need a very high quality audio system : neutral, powerful and versatile.
Jean-Luc Ohl, a talented engineer (from company 44.1) did the setup, QSC programming and all measurements analysis.
The listening room is about 6m x 5m x 4m (120 cubic meters), high ceilings (3 m to 5.4 m), with few parallel walls, well treated with 2 to 10 cm rockwool on most walls (total of 4 cubic meters absorbing material). Measured reverberation time RT60 is 0.2s at 500 Hz and because the room is located in a very quiet place with no street nearby, its residual noise is low, 15.5 dB measured with NTI XL2 and class 1 microphone..
Audio system details
Schematics
1/ In-room MMM measurement without subs and without equalization, measured thanks to loudspeakers.audio method, score=7.3
2/ Same MMM measurement with multi-subs and with FIR equalization score=8.8
After this quick presentation, I’ll add technical details soon and explain some choices.
