Thank you, Dennis. This will help

Listening to the CD and reading instructions that are legible. There is info in the booklet complementary to but not in the audio tracks: Track 1 Inroduction: Introduces the C-4000 & congratulates you on "the ultimate listening experience" afforded by SH. The recorded tracks will help set up the system with SH but will benefit users of ordinary playback equipment. Be sure to set your system controls to stereo operation! Track 2 Loudspeaker Phasing Instructions: How to determine by listening to the track; how to correct. Even if you do not understand speaker phasing, one can just listen and know whether or not a problem needs attention. Track 3 Absolute Phase: Ditto above. Track 4 & 5 Frequency Response: tones to check speaker frequency response (and the listener's hearing!): 1 kHz, 15 kHz, 10 kHz tones–the 15kHz tone is very hard for me to hear unless close to & on axis to the speaker; ambient household & environmental noises compete. Yikes! Then: 5kHz, 100 Hz, 50 Hz. Then: 1000Hz, 24 Hz, 16 Hz. Check your subs, your hearing & room vibrations! Track 6 Log Sweep: sci-fi spacecraft taking-off sound effect with low-to-high frequency sweep. Cats think it is creepy. Track 7 Electrical Balance: switch Stereo/Mono switch on & off; the sound volume should diminish in mono mode. Track 8 Autocorrelator Adjustment: I hear nothing on this (using CT-7). Track 9 Peak Unlimiter Adjustment: ditto above. Love the name. Track 10 Time Delay & Echo Density: nothing for the CT-7 to attend to. Track 11 Introduction to Tracks 12, 13 & 14: Designed to be used with SH; noise bursts on the left channel, then the right; these noise bursts are guides for adjusting speaker toe-in, speaker placement and optimum listening position (left-right, front-back). Properly set-up, the sound appears to be coming from over there (point 45 degrees out to the side), not from the speaker. Leaning the head towards the side of the speaker (leaning right with the tone only from the right speaker) shifts the image left towards the middle, between the speakers; leaning left shifts the sound, in this case, towards the right speaker. Back in optimum position, the sound is way off to side, out there somewhere, definitely not from the speaker. This could be a party trick! Track 13 Music Track 14 Holographically encoded music: if you do not have SH. Track 15 Pink Noise: Yes, but don’t know how to use this. Cannot read the instructions.

The printed instructions to my SH Holography Demonstration-Calibration Test Disc (CD) are tenaciously stuck together. The top halves of pages have yielded to patient separating but the bottom halves are losing print. I do not see the instructions in the Database. If it is available, please point me in the right direction. Much obliged, friends.

I am # 1 Godzilla fan; reruns of the classics, especially with Raymond Burr, captivate me. Will be looking for this at an iMax theatre-big, BIG, BIG! .

Hello, Bob. Thanks for the pictures sans cats. I've got them–so does my ALSs. Polk SDAs… Your fluffy white companion looks great company for music from a great system. By the way, your are entering here the OCCD Reality Distortion Field. Might as well surrender.

All of the early Pat Metheny'Group recordings on ECM are on my remaster wish list. Nonesuch is issuing remasters of the later work. Mahavishnu Orchestra recordings could use a redo, the sound is a compressed muddy mess.

Bowers & Wilkins offers Society of Sound, a music subscription curated by Peter Gabriel & Real World Studios and the London Symphony Orchestra. Trial members can try out the music for free & download selected tracks. Members receive two hand-picked studio-quality album downloads each month plus a selection of catalogue albums; all available in Apple Lossless or FLAC 24-bit. I am doing the trial; the catalogue offers artists & music I would not normally consider or even know of and so far have been pleasantly surprised. The FAQs were helpful for me now just getting into digital downloads, a new dimension in my music library.

In, thank you very much.

From what I am learning in the forum, tightening too much the screws may damage the ribbon assembly and too little allows buzzing. How does the original factory assembly avoid this? I would be in interested in learning how the factory assembles the ribbon components. My imagination runs off to some miniature torque wrench that should be in my tool kit. Perhaps someone in-the-know here would like to share insight into this matter. Back to listening again today and minimal (1/8-ish) turns. So far each screw1/8 turn has met no resistance of the kind sensed when a screw has reached or is very near the stop point. Pat Metheny recordings, his electric guitar tone, reliably buzzes, so it will be Pat & me today.

Thank you, makes sense, but being cautious comes with inexperience on my part. How far has any one particular screw been turned been by anyone doing this procedure? I've done 1/8 so far and not resolved the buzz sites. 1/4? 1/2? Proceeding with caution (jeez, you'd think I was doing touch-and-go brain surgery). Thank you for ongoing support.

Regarding tightening slightly the screws at the level of buzz, may this be performed whilst music is playing or is it to be done with no audio signal. I have identified at least two, maybe three, buzz zones.

You fellows are sharp. Back to the second hand store for another wine rack.

I will apply delicate attention to the screws this weekend, thank you for the emphasis on minute turns. As things stand now the components hide out of sight behind the left speaker, the True Sub Jr. behind the right speaker.

Thank you for the warm welcome, that is very nice. I will review the posts regarding ribbon buzz & selecting appropriate screws to minimally tighten, as well as humidity, although I think it is a low humidity situation indoors this winter–but humid summers in Northern Virginia. We tend to keep the windows open spring through autumn. What would be the benefit, if any, to running a hair dryer set to low heat & low speed from a distance, not close, over the buzzing area? Bad idea? Not trying to shrink wrap the ribbons like the window insulation treatments I put up in winter. Future plans: perhaps introduce the second M1.0T into the system, both set mono, driving their own speaker. I have yet to top-out the M 1.0T LED lights, so would there be any real sonic benefit? My guess is probably not. These, as I have learned here, are the non-inverting models so a flip of the switch on the back panel would precede a new hook-up. Still experimenting with the Sunfire True Subwoofer Jr. crossover level & volume. The ALS's bass is incredible, more so than in the past and I attribute that to room placement, having back and side walls walls not opening into another room or hallway. I have set the crossover at 35 Hz and the volume rather low and the low end is very nice. My wife said it is good to have Big Music (her words) again, meaning the sound & soundstage of the ALSs. I will post an update as things proceed. And to correct a mistake, that is a CT-7 in the system, not TFM-35. Thank you once again for the cordial advice and hospitality.

The old ALS Silver Mk IV s had lost all 6 subwoofer surrounds (literally all the way around) and one ribbon was buzzing. Ugh. In came the Polk SDA-SRSs hooked to M 1.0T amp, TFM-35 preamp and a Yamaha 5-disc changer. A pair of Bose 901 Mk IVs sat on the sideline needing speaker replacements. A fortunate situation indeed but I sighed at the thought of giving up the Darth Vaders in spite having the Big Coffins in their place. Luck enters the scene: I discover The Carver Site. Eureka! Following the forum discussions I ordered 6 woofers from Dynavox months ago, Over the weekend my wife and I replaced all the degenerate woofers. Needed to drill new mounting screw holes, three of four for for each woofer, and make ugly solders that actually got better by the end. Holding our breathes the ALSs were plugged into a Denon multi-channel receiver that was powering Mirage Nanostat 5.1 speaker set-up. The surgery worked! Not as astonishing as I had remembered but a start. Today the M 1.0 T/TFM-35 combo was connected via a Sunfire True Subwoofer Junior line level high-pass output set to approx. 40 Hz. The room is 25 L x 12 W with ALS at one of the 12 wide sides and out three feet from the back wall. At first, no sound whatsoever. The fault was Tape Monitor buttons pushed in whilst cleaning the TFM-35 face. One click and voilà! My mouth dropped open, my breath stopped. Oh my, my, my – this was astonishing! It was My Mourning Jacket's Evils Urges slamming sublimely . I had forgotten how astonishing music-at-home can be. There is a ribbon buzz and a subwoofer hum to sort out so back to the Forums for collective wisdom. My sincere appreciation goes out the Carver Site Forum members for their help. And my wife.
