Inside the Session
As many of my family and my most tolerant friends will tell you, I am a ‘nerd’ when it comes to engineering recordings, choosing and setting up microphones, cabling, mixing… in fact anything to do with the entire process. When I was asked to engineer a project that featured an entire symphony orchestra in an iconic venue and with the aim of capturing the performance as cleanly as possible, simultaneously to analogue and digital, well… the whole experience was one I will treasure.
The two people who were the driving force behind it were Mike and Françoise Valentine from ‘Chasing the Dragon’ I have worked with them before but we were all determined that this recording of Rimsky-Korsakov’s ‘Scheherazade‘ with the National Symphony Orchestra conducted by John Andrews, Leader Katerina Nazarova would be the ultimate illustration of our joint philosophy.
So below is a detailed description of how we went about it, the pleasures, the pitfalls, the problems, but overall the absolute joy of recording ‘Scheherazade.’
1. Recording Scheherazade with the National Symphony Orchestra Microphone Layout & Setup
Both Mike and myself are obsessive about mic choices and placement, and this session was no exception.
Details on main stereo pair, outriggers and spot mics placements
- Main stereo pair: Flea M251s on a Jecklin disc, giving both warmth, top-end detail and stereo separation across the orchestra.
- Outriggers: Two Flea C12s, strategically placed to support width and sectional definition for the bass and violin sections.
- Spot mics:
- Neumann KM184 as an accent on tuba
- Neumann U89s on the brass section and french horns
- Neumann U47 FET on harp
- Neumann TLM67s on lead cello and timpani
- Flea C12 on woodwinds back row: clarinets, oboe and fagotto for definition and accent
- Neumann KM184 on woodwinds front row: flute & piccolo for extra accents
- Flea C12 on percussions provided loads of dynamics
- One dedicated Flea C12 on Katerina Nazarova solo violin providing extra definition and accent
- Binaural: Neumann KU-100 on the main stand, underneath the Main stereo pair.
Details on amplification and signal routing
The microphones were captured using Focusrite RED 1 microphone preamps, while the Neumann KU-100 was captured by a Neumann preamp. Some of the re-amplified signals were then split into two parallel chains:
- Analogue: Studer A820 ½-inch, running 30 ips. Recording The Masters SM900 tape stock was used for masters and LPR90 for copies. We carried out full alignment (bias, azimuth, and level 320 nWb/m) on site, ensuring maximum headroom without pushing noise up.
- Digital:
- Two Zoom F8N recorders at 32-bit/192 kHz, timecode-locked to expand channel count.
- Two Tascam DA-3000s capturing both 24/192 PCM and DSD128, for the KU-100 binaural feed.
- One Nagra VI where the Zooms were connected to for additional monitoring/recording and playback.
This wasn’t about over-miking — it was about options. Every mic placement was chosen to preserve tonal balance, separation, and orchestral texture while allowing the mix engineer to adjust levels in mixdown. I could commit the main stereo pair to tape while knowing I had pristine digital stems for further work. It’s belt-and-braces, but it means no sonic detail is left behind. On the next session I am going to try and do some comparison with the BAT 1588.

2. Cabling & Power Management in the Scheherazade Session
How mains distribution, grounding, and high-spec cabling protected the recording chain.
Valve microphones prefer stable mains feeds. To deal with this we split the power distribution, one feed for mic power supplies and another isolated feed for the recording system. Heavy-gauge CY cables reduced voltage sag and helped suppress induced hum.
Signal cabling was also carefully specified:
- Vovox between valve mics and power supplies
- Nordost Odin 2 and Zensati Zorro XLRs were deployed on the most critical analogue lines, for extremely low capacitance and dielectric loss.
Cable runs were laid with grounding discipline in mind, keeping mains away from signal cable therefore keeping RF pickup as low as possible.

3. Henry Wood Hall: Acoustic Space & Orchestral Recording Advantages
Why the hall’s architecture supported natural dynamics and reverb.
Henry Wood Hall’s high ceiling and broad dimensions worked in our favour, giving a long but controlled reverb tail. The Flea M251s with the Jecklin disc locked down a stable stereo image, the outriggers added lateral spread and the spot mics gave definition without collapsing depth. Playback reveals clean sectional separation—strings, brass, winds—and a natural sense of the Hall’s air.

4. Recording Scheherazade with the National Symphony Orchestra Post-Production & Mixing
Neve console at AIR Studios, producer/engineer collaboration, mastering workflow.
Mixing was completed at AIR Studios on their custom Neve A7971 console engineered by Jake Jackson with Mike and Françoise producing. Decisions on takes and sectional balances were made in consultation with John Andrews and Katerina Nazarova.
For vinyl, mastering engineer John Webber cut lacquers on a modified Neumann VMS-80 lathe working half-speed from high-resolution sources. Half-speed cutting stabilises HF phase and transient accuracy, which was particularly important for string tone and percussion detail.
5. Key Technical Challenges in Recording Scheherazade
Flux levels, valve PSU hum, synchronisation, cable routing and logistics.
- Dynamic range: Orchestral tuttis pushed flux close to tape limits. We calibrated carefully to keep hiss low while holding enough headroom for peaks (320 nWb/m).
- Valve PSU noise: Valve mic power supplies were isolated on their own mains feeds to prevent hum coupling into signal chains.
- Synchronisation: Timecode-locked Shure F8Ns ensured accurate alignment of digital channels and enabled direct comparison against tape captures.
- Cable routing: With costly, high-spec cables in play, the routing was meticulously executed to prevent induced noise.
- Logistics: Running a tape machine, digital rigs, and valve mics in a live hall under time pressure required strict workflow discipline.

6. Recording Scheherazade with the National Symphony Orchestra Comparing Analogue vs Digital Formats
Tape (SM900), PCM (192 kHz), DSD128, and half-speed mastered vinyl.
- ½-inch Tape (SM900 at 30 ips): Most natural transient handling and hall decay. No NR required. Wide headroom.
- PCM (192 kHz, 32-bit float): Accurate, clean, and edit-friendly. Reverb tails slightly less continuous than tape.
- DSD128 (DA-3000): Smooth and analogue-like especially in string harmonics. Less flexible for editing due to the lack of editing software.
- Vinyl (half-speed mastered): Preserved hall energy with extended HF accuracy. Playback system dependent but musically convincing.

8. Why This Orchestral Recording Matters
The importance of a consistent signal chain from capsule to playback.
Capturing Scheherazade this way for Chasing the Dragon reinforced a point for Mike, Françoise, and myself – orchestral recording isn’t about any single component. Success comes from a consistent, interference-free chain from capsule to final medium. When mains, cables, alignment, sync and mastering are all controlled, the result is a recording that presents both the smallest detail and the full dynamic sweep of an orchestra in its natural acoustic space.

9. Conclusion: Format Comparisons & Audience Response
Benefits of parallel analogue/digital recording, sales success, and listener reception.
The Chasing the Dragon Scheherazade sessions showed us the real benefits of running tape, PCM, DSD and then a mix down on vinyl. It allowed us to compare formats directly under controlled conditions. Each medium revealed its own strengths, from the headroom and transient response of analogue tape to the precision and editability of high-resolution PCM, and the smooth tonal continuity of DSD. By aligning these chains carefully Mike, Françoise and I could deliver releases that play to the strengths of each format rather than forcing a one-size-fits-all solution. The proof has been in the response: the vinyl editions have sold strongly, the tapes continue to attract collectors, and listeners report that the recording captures both the drama and intimacy of Scheherazade. That tells us the effort spent on cables, power, tape alignment and synchronisation translated into what matters most—music that people actually enjoy playing back.
