Für diese Testplatte hat Analogue Productions zahlreiche Fachleute
aus der Branche zu Rate gezogen, darunter Mastering-Ingenieure, Audio-
und Plattenspieler-Experten sowie audiophile Hörer. Das Ergebnis ist
eine erstklassiges Tool, um ihren Plattenspieler professionell zu
kalibrieren. Viele Testaufnahmen wurden in der Vergangenheit gemacht, um
eine Fülle von Geräten zu prüfen. Diese Schallplatte konzentriert sich
auf den Plattenspieler, den Tonabnehmer und die Abtastnadel und wurde
entwickelt, um die grundlegenden Signale zu liefern, die für eine
einfache Kalibrierung erforderlich sind. Hinter dem Projekt stehen Barry
Wolifson von Sterling Sound in New York City und Clark Williams von
Analogue Productions.
Wir empfehlen die Verwendung
von „L’Art du Son“- LP-Reiniger für die Nasswäsche Ihres Vinyls. Auch
neue Platten aus hochwertiger Fertigung profitieren davon noch einmal.

"Back
in the golden age of vinyl there were many different test LPs available
- all rather similar to one another. Analogue Productions decided to
create a modern test disc that hasn't been done before, and have
succeeded. It specifically addresses the turntable, cartridge and
stylus." - John Sunier, Audiophile Audition, February 21, 2010
"The
disc is indispensable for anyone who is dedicated to the most accurate
adjustment of his LP playback system and thus the best sound." - Harry
Pearson, The Absolute Sound Editor
"…The modern renaissance in
vinyl over the past decade, coupled with the startlingly high
performance of today's best LP front ends, has created the need for a
new standard in test records. And that new standard is undoubtedly The
Ultimate Analogue Test LP from Analogue Productions. This new disc has
been meticulously assembled in collaboration with some of the world's
greatest technical experts in record cutting…a 'must-have' for any
analog enthusiast." – Robert Harley, The Absolute Sound, October 2008
"The
speed stability of this test record is outstanding and below the
measurable threshold, that's what it's supposed to be. With most test
LPs, the speed is erratic caused by off center holes and warps in vinyl.
I have over 40 test records and for most functions they are useless.
You made a great test LP, I used it to set up and measure my new Rim
Drive and without it most of the testing would have been useless. It's
unbelievable, there is no wavering." – Harry Weisfeld, VPI Industries
"The Ultimate Analogue Test LP from Analogue Productions is something
that could only have been dreamed of a few years ago. Now it's a reality
and an indispensable tool for setting up and getting the most from your
vinyl rig. It's 'all about the music' for us vinyl lovers and I can't
imagine how we ever did without something like this for so long! Bravo
to Analogue Productions/Acoustic Sounds for making this the true
Ultimate set-up disk, a tool that will enable us to get the most music
and good sound from our record collections." – Steve Hoffman, mastering
engineer
"The Ultimate Analogue Test LP is a milestone and very
powerful reference for those truly concerned about getting the very best
performance from an analog (vinyl) front end and also for those
professionals who manufacture the related analog front end products. To
start with, Track One very accurately provides a 1kHz tone at 7 cm/s
mono (in-phase, lateral) NAB OVU standard reference level, which has
been the industry standard since 1964. This supercedes the long-outdated
RCA 5 cm/s (3.54 cm/s stereo) test level. Track One can also be used as
an outside track wow and flutter reference as will the inner Track
10…two ways to approach this measurement. A close look shows that each
track on this disc can be used in multiple ways far beyond the list
provided in the limited space on the record jacket. Hats off to all of
those involved in making this outstanding test LP." – Keith Herron,
Herron Audio
"The Ultimate Analogue Test LP from Analogue
Productions is the quintessential tool for setup and fine tuning of ALL
analog systems…Pure Science yields High Performance." – Dan Babineau,
Technical Editor, TONEAudio Magazine "First of all I have to say it
comes along in close to perfect manufacturing quality. In comparison to
lots of other test records available in the market there are nearly no
warps. So when it comes to talk about a test record, the first thing
that is absolutely necessary is perfect flatness of the disc. The second
and third tracks on the first side of this record are very good tools
to adjust azimuth to a certain degree without test-equipment. Track 10
is a perfect 3150 Hz tone that is mastered close to perfection. In
direct comparison to a German-made product, one can see that level is
kept in a much narrower band. So there is only very small amplitude
deviation visible. All of the other tracks are very useful as well. I
have to give my highest recommendation to this record – a must have for
any audiophile!" – Dr. Christian Feickert, Feickert Analog Products
"In
having created a special grinding system we at Basis have created
turntable drive belts precise to within a fraction of a Micron. Combined
with our similarly groundbreaking work in creating absolutely true
bearings and platters Basis has broken new ground in turntable speed
stability. The result is that the speed stability of Basis turntables
now exceeds the limits of the very test records used to test speed
stability. Only one out-of-print test record so far had been up to the
task. The recent test record you sent makes the second. The lack of
drift in the test tone makes this the most close to perfect speed check
we have found to date. Thank you for bringing this record to my
attention." – A.J. Conti, Basis Audio
"Yes, I'll occasionally set
up a cartridge visually to listen casually. However, all serious
listening is done by setting up with the 'Ultimate Test LP,' it's always
interesting to see how far off I am with a visual set up. Some of the
adjustments are very fine. I don't think one can be certain that their
cartridge is set up right without this disk." – Michael Yee, Michael Yee
Audio Analogue Productions set out to produce the ultimate test record.
We’ve consulted many experts in the field, including mastering
engineers, audio experts, turntable experts and audiophile listeners, to
create a test record that's never been made before. When Barry Wolifson
from Sterling Sound in New York City called us with the same idea we
had been thinking about – that being to create the ultimate test record –
he and our audio expert Clark Williams began to brainstorm and research
ideas until they were both completely satisfied with what should go on
the record. Most of the test records in the past have been made to test a
variety of equipment. This test record excludes silly cannon shots,
typewriters, voices on one channel and other useless fluff. This one
specifically addresses your turntable and cartridge. It’s designed to
provide the basic test signals necessary to calibrate a turntable or
cutting lathe as simply as possible. Most of the signals have specific
implications, but it is certainly possible to use them in any number of
novel ways. This record was pressed at Quality Record Pressings on 200
gram vinyl.
Side 1
General Reference Level This 1 kHz reference tone will allow you to establish a “base level” for all measurements.
Track 1
1Khz
reference tone 7cm/s Mono, in phase (Lateral) Basic reference for all
measurements, adjust meter for maximum convenience (in the studio 0VU).
Adjust preamp channel balance for equal output. Also used to check the
offset angle of the photo cartridge; L&R signals should be exactly
in phase as displayed on an oscilloscope. Azimuth Adjustment
Track 2
1kHz reference level Left channel only Measure Right channel output.
Track 3
1kHz
reference level Right channel only Measure Left channel output. The
object is to sit the stylus exactly perpendicular in the groove. Twist
cartridge about its radial axis until the measurements from Track 2 and
Track 3 are equal or very close to equal for both channels. High
Frequency Adjustment Tracks 4, 5 and 6 are used to calibrate the RIAA
high frequency equalizer of a phono preamp. This will be used to
calibrate a mastering lathe’s phono preamplifier or any phono
preamplifier that has these adjustments.
Track 4
1 kHz tone at -20 below reference level, Lateral Reference for High Frequency test.
Track 5
10 kHz reference tone at -20dbu, Lateral Adjust the high frequency until the output level equals that of Track 4.
Track 6
1
kHz to 20 kHz sweep at -20dbu, Mono (Lateral) The AC millivoltmeter
reading should stay constant across all frequencies. There are a number
of factors which can affect frequency response, including cable
capacitance, cartridge loading, tracking force and worn parts. Because
of this, it can be difficult to achieve perfectly flat frequency
response. Sometimes by making small compromises in the 10 kHz
adjustment, a better overall frequency response can be achieved. Low
Frequency Adjustment Tracks 7 & 8 are used to calibrate the RIAA low
frequency equalizer of a phono preamp.
Track 7
1 kHz to 20
Hz sweep at 0 VU (Lateral) Play Track 7 and measure the output with your
AC millivolt meter. Ideally, the output will be flat across all
frequencies. When viewed on an oscilloscope, the amplitude would remain
constant during the frequency downsweep.
Track 8
100 Hz reference tone at 0 vu (Lateral) Adjust LF Eq to reference (which is your reading from Track 1).
Track 9
VTA
adjust This is an IEC intermodulation distortion (IMD) test signal;
60Hz & 4kHz 4:1 ratio. Using an IMD tester, adjust VTA by raising or
lowering the tonearm for minimum distortion.
Track 10
Standard
Wow & Flutter test signal; 3150Hz The Wow & Flutter meter will
give dynamic speed variations as a percentage deviation from nominal.
Also, the frequency counter should read exactly 3150 Hz for nominal
speed. You can use the Hz function on your multi-meter (if so equipped)
to verify speed here as well. You can also use to find the measurements
at 45RPM. The correct reading at 45RPM would be 4253 Hz (45/33.33) x
3150.
Side 2
Track 1
Anti-skating test; 315Hz
amplitude sweep to +12dbu (Lateral) Signal should remain clean in both
channels up to the highest level, both audibly and as viewed on an
oscilloscope. In case of distortion, increase anti-skating force or
decrease anti-skate until breakup occurs equally in both channels. The
left channel information is inscribed on the inner groove wall, the
right channel information, on the outer groove wall. Because of the
offset angle of a pivoted tonearm, a constantly varying vector force
biases the arm towards the center of the record causing the stylus to
lose contact with the outer (i.e. right channel) groove wall. Both
linear and modulated groove velocity, tracking force, stylus profile,
and vinyl composition are contributing factors. The anti skating force
attempts to ameliorate this by applying an opposing similar force. It is
also accepted that the overall force vector increases as the tonearm
approaches closer to the spindle or end of the record.
Track 2
Pink noise lateral
Track 3
Pink
noise vertical Used for cartridge “demagnetizing” You can also use this
track to loosen up the cantilever’s suspension to help break in a new
cartridge. Play these tracks five to ten times after every 300 hours of
normal LP playback.
Track 4
1kHz @ reference level, vertical
This out-of-phase signal should cancel to nothing when summed to mono.
Any signals still present are distortion artifacts, lack of channel
balance, or timing (phase) anomalies. This test can be a second
confirmation of anti-skate adjustment.
Track 5
1kHz to 10Hz
sweep @ -20 below reference level, vertical Resonance anomalies in the
tonearm / cartridge interface will show up as amplitude peaks and dips
as the frequency sweeps down. Once again, by listening in ‘Mono’ it is
easier to hear the distortion artifacts.
Track 6
Silent
groove for bearing rumble and table isolation During playback of this
track, nothing should be transmitted from the turntable to the speakers.
Replay the track and gently tap on the rack or base that the turntable
is resting on. There should be little or no thump transferred to the
speakers. This track will help you experiment with turntable isolation
methods and products to be able to get the most out of your playback
system. You may want to use a closed or sealed headphone for best
listening results, or a stethoscope on the plinth.
