The picture above was just a table of contents of the reference signal so confusing. Differences between

the reference signal at the output of a stereo cartridge was not allowed to check. Sweep in the 1kHz

signal is as described in the above reference levels are slightly lower than the rate constant amplitude

over the full 4kHz 35.4mm / s has. RIAA has constant properties except when recording high-frequency

characteristics of the recording. Sweep Pilot Signal 1kHz signal prior to each recording level than the

reference signal level is low because each Sweep in 1dB 1kHz are explained according to the same level for the signal.

1kHz REFERENCE LEVELS OF TRS-1007



TRS-1007 1kHz reference frequency in the frequency response measured at 1kHz at the level of surfing the net, so I bought there was a question whether the same recording level (like the above conclusion is

only a difference of about 1dB I understand that.) ー things like shopping was high on themselves, we

have quite the thing. Sony XL-55mono because sensitivity is equipped with a table display properties

(1kHz 5cm/sec, 45 ° in) and there, TRS-1007 is the 1kHz peak 3.54cm/sec 45 ° is supposed to be.

PICKUP DATA stereo converted for a vote because of H (horizontal) seems to forget correct. CBS

STR-100 test record the way the 1kHz peak 5cm/sec, 45 ° was a reference level (for a stereo cartridge

in fact do not believe more than there used to believeー.) Note: Sony's XL55mono twin coil power has

become a figure eight mechanism. "To play to do is build a true record monaural, the ideal is not to

determine the composition vertically unwanted by the effect, pinch, and the warping of vinyl cartridge" for the stereo, so you and XL55 not appear to be the same ( structure is expected to change the

alignment of the lower left stereo figure eight coil). XL-55mono see at first glance from side to side

across the coil width, cantilever, as in 8 ● 8 (bottom right image).

Six Right (R) 2.5 3.54

Seven Lateral (L + R) 3.54 5

Eight Vertical (LR) 3.54 5



Using the following TRS-1007 Dynavector DV-50A is a table of properties. Degrees 45 peak 3.54cm /

s horizontal peak 5cm / s are displayed in terms of (or honestly horizontal peak 5cm / s and I used to

watch the band.) Rectifier: RMS output level to understand description of the value that has been shown

effective. The sensitivity of this stereo cartridge IEC notation of 0.2 * 1.4142 / 3.54 = 0.08mV/cm/s be.

55 XL-sensitivity stereo 1kHz peak 5 cm / sec, 45 ° in 0.2 * 1.4142 / 5 = 0.057mV/cm/s. 0.2mV output

actually see it the same as it is different.

I did not have confidence in April 1978 AES JVC Yohodo of this Convention TRS-are described as

follows: the technical characteristics of 1007. interferometry (interference of light) there is a strange



word, Buchmann-Meyer (1930) well-established method to measure the velocity amplitude of the old grooves with the interference of light developed by the [band of light] of is.

New Approach for Sweep Frequency Test Record: A low cross-talk precision sweep frequency test record is mastered by the half-speed cutting system, which uses an advance-ball and the technique of synchronizing frequency sweep speed with platter revolution. The amplitude is calibrated by the interferometry method. The resulting test record has specifications of frequency response, 20 Hz to 20kHz + 0.5 dB; separation over 25 dB below 50 Hz and above 10kHz; and separation over 35 dB in the mid-range.

Frequency record is very likely spot fine, while maintaining the accuracy of 20Hz-20kHz sweep DGG recording DIN 45543 (1984) too much and do not like this record.

TRS-1005 with characteristic example of the table

Like the JVC TRS-1005 Sutereotesutorekodo of 1kHz-50kHz Sweep L, R AB 9 was repeated to test the difference between the inner and outer cross talk and high frequency characteristics of the signal was

recorded on the same side . Here is none of DENON DL-103C1 (characteristic for each table has about

needle exchange.) The test records the signal level degrees 45 peak 3.54cm / s But as usual horizontal

peak 5cm / s has been translated into view. JIS C5503 (1979) "pick up" The recommendations are:

output voltage measurement cartridges "for the velocity amplitude mono 50mm / s, the velocity amplitude for the stereo record 35.4mm / s must be converted to" to that I have not converted to the opposite view.

four channels are stamped on the back of the Onkyo Kobe office this record is like a white jacket was

distributed applications to service companies. Test Record 4-Channel JVC TRS-or seems to be part of

the 1006 prototype. 4 channels, so I started collecting records since the 4-channel turbulent

Demodulator luckily do not have. Content of each band roughly 2channel stereo on a speculative play

(especially behind the RG-1257 is uncertain.)

Toshiba EMI Germany of course, not intended for older DIN test record. JVC TRS-1001 standard is a

mono record that conforms to JIS C5507 Toshiba EMI LF-measuring overall performance characteristics similar to the 1003 RIAA seems to also include signals Spot (The recording level 1kHz 5cm / s lower should have been recorded level.)





German version IEC98 (1987), Appendix to the frequency list of records found: 1kHz reference signal in / between left and right output (channel balance) / measurement frequency and output frequency

response and crosstalk separation. "Characteristics of normal play recording characteristics (RIAA =

IEC = BS = DIN = JIS) is different from that required to compensate play" notes are. IEC in the way of

the reference signal level 1kHz (0dB) is different from the reference level, so each record has not been

identified. In Japan the past JIS records standard (C5507 & C5514) mono in accordance with (H, V)

velocity amplitude of the peak 50mm / s, the direction of 45 degrees stereo (L, R) velocity amplitude of

the peak 35.4mm / s employ seems. These records were in any event they are now out of print in the

new is unavailable. EIAJ SS41 Teichiku the signals of the 3.15kHz WOW / FLUTTER Test Record

(Level: peak 8cm / s lateral = effective 5.6cm / s lateral) Why do not you heard it was that made us

"know that the old not in stock anyway, "was said. JIS C5521-1975 (final) test method Honomota the

JIS C5514 (record standard stereo) at 3kHz band (SS-2) was supposed to use, DIN has 45545 IEC and CCIR international standards adopted by The auxiliary system himself so as to make a record 3.15kHz

signal measurements. WowFlutter common reference frequency meter is ± 10% at 3kHz because it

allows essentially 3.15kHz reference signal which can measured by the assay is the same.





Age was 60 CBS STR-popular recording characteristics 100 (L / R spot frequency) Concept of.

Constant velocity amplitude above 500Hz, 500Hz, so the amplitude less constant rate proportional to trace the ideal type of pickup to play RIAA RIAA frequency curve will be the difference between the pink line recording characteristics.

DENON has also put a few test records in PCM technology used in DENON AUDIO TECHNICAL

TEST RECORD 1976-1979 is well known. Japan Audio Society The XG-AD-1 was a 7001 reprint.

However, XG-7001 (released August 1976) and XL-7004 ~ is the first released single of the album
