Pro audio with Hauptwerk

PostThu Jun 03, 2021 11:02 pm

Recently I had the opportunity to transport my converted Schober Recital model to a couple of venues to be used for "Recitals" :). The first was for an our local AGO Chapter. The original plan was for an outside event. We found a small park downtown and using a barrage of speakers would create an outdoor acoustic cathedral if you will. Mother Nature had other plans so we moved the program, keeping the original audio design, to a nearby school gym. The second recital also took place in a school gym. This one had acoustic panels very high up the walls which cut the reverb down to maybe 1.5 seconds. For both gigs I resorted to pro audio powered stage monitors. I'm not a fan of using these for HW since they color the sound too much. However they do solve lots of logistical problems. Setting up a temporary Hauptwerk rig is met with similar challenges stage bands and club musicians face when bringing in their own sound equipment to a venue. It's too bad they don't have a stage monitor with the fidelity and flat response of a studio monitor . . . hum :? .

Well I think I found something, the QSC K10 and CP8 series of powered speakers! I have done several remote Hauptwerk 'gigs' where I have to setup either a single keyboard or a full console. I've tried Yamaha, Yorkville, Peavey (yuk!), Rockville (worse!), JBL, and Mackie. The results were all the same . . bad. For these recent two recitals I went with QSC equipment and was pleasantly surprised. In fact for the this last one, the compliment was:
8 QSC K10s,
2 QSC CP8s,
1 QSC KS112 sub,
1 Rythmik audio FV15HP.

The K10s have an onboard DSP tied to EQ presets as well as a parametric EQ. My personal HW setup consists mainly of Behringer 2031As. I used it as my sound reference point working a bit with the QSC DSP functions but mainly the MOTU's built in EQ to bring them up to a respectable 'studio monitor' sound. The Schober console and the whole QSC rig with subs was setup in my garage. So, with identical organs and registrations loaded on each, I got a work out running back & forth between garage and studio (2 different levels) for a true A/B comparison. Ah, what us sound geeks go through to achieve convincing audio! The result, I'm happy to report, is I got it to a studio quality level of about 91%. For some ranks I feel I was right at 100%.

The second recital was given by a young, Julliard hopeful, whiz kid. He has a nice Hauptwerk system at home and is very astute with the rank voicing tools He has a keen ear of what ranks should sound like individually and in an ensemble. We set this 10.2 audio channel on the stage in the gym a few days before the recital with all speakers in the final concert position. Using the Hauptwerk voicing tools, he fine tuned the sound even closer to the proverbial 100% golden audio mark. I have to admit I don't think 20 channels of studio monitors would have sounded that much different, especially to the audience! I have to give kudos to this QSC equipment as did a couple of other organist who were in attendance. I believe a contributing factor is the treble driver isn't a horn or placed in a conical shaped enclosure.

The sample sets were played back in stereo due to some L & R voicing tweaks done on many notes. I keep reminding myself that this is a temp setup and we need to have a big sound that isn't complicated.
Here the routing design:

Pedal division -
Right - K10 + KS112 sub (Line out of K10 to LFE input of sub, cut off frequencies adjusted accordingly)
Left - K10 + Rythmik Audio sub (Line out of K10 to LFE input of sub, cut off frequencies adjusted accordingly)

Main organ ranks - (1 group with HW default algorithm)
3 stereo pairs of K10s

En Chamade and other select solo voices -
1 pair of CP8s (highest speaker elevation)

All L&R stereo pairs were respectively left and right of the console. I received many compliments on the over all sound. The star was the F15 Rythmik Audio sub that aptly conjured up frequencies in the teens when needed. I had couple inquires after the recital about how that was achieved. Sample sets used were Friesach & Bellevue Casavant.

I wanted to share this experience with the forum. When the need arises for a 'Hauptwerk to go' solution, don't hesitate to consider these QSC powered speakers! Here is a shot of the final setup on the move in day:

Congrats, good work. As always, it's all in the ears of the beholder. Voicing controls are seriously important. While the current version of HW is a great improvement over what was previously available, I'm hoping for more (improvements) in future versions,

Along those lines, some tutorials on the how to would be (essentially) welcome. Likewise a hardwired "device" to connect externally to these voicing controls would make real time adjustments much easier to deal with vs a mouse or even a touch screen. Altho a large touch screen devoted to voicing schemes on a rank by rank basis?

I can confirm that the QSC K 8.2 is a reasonable speaker model, if you need a lot power with a reasonable (but not perfectly) flat frequency curve. These speakers offer digital signal processing (DSP) and I use ten of them in the "Monitor" pre-set, bus have switched the high-shelf filters to -3 dB for frequencies at 8 kHz and above.
I have installed four front pairs and one rear pair in an adio studio and needed to mount two pairs approx. five meters above the ground. So, it was essential that I chose speakers suitable for permanent mounting.
The QSC K 8.2 and K 10.2 are basically PA equipment with better frequency reproduction. However, other than studio monitors they do hard with silent sounds (they do not fade-out smoothly, but retain some noise). The decision to install them was mainly based on their high max. volume (which I needed for this room) and their mounting options. For at home I do recommend less output power with better frequency curve, i.e. very good studio monitors.

Thanks for posting, I’m glad to hear that there are good pro audio options for Hauptwerk out there. I have had two Yorkville nx25’s for many years, and I have been very happy with them. I’m not sure my ear is sensitive enough to detect how flat the frequency response is, but it sounds “flat” enough for me. I only use them L and R for stereo audio however, and usually only fairly dry sets. I’m quite happy with them though, and have had compliments from many musicians visiting my house how good they sound. I usually only listen to them at fairly low volume however, never loud or maxed out.
