ORTOFON TEST RECORD

Thank you for purchasing the Ortofon Test Record.

Ortofon’s new Test Record is designed to allow you to verify your HiFi system in the most natural audio

surroundings at home. The Test Record contains special test signals developed for analyzing cartridge

performance as well as its interaction with your tonearm and turntable.

The Tests

Each side of the record consists of 15 tracks which have been cut from 1-4 and 5-15:

1. Frequency Sweep Left Channel 800 Hz – 50 kHz. Log. 28 sec. Linear cut* (800 – 20000 Hz ±1,5 dB)

2. Frequency Sweep Right Channel 800 Hz – 50 kHz. Log. 28 sec. Linier cut* (800 – 20000 Hz ±1,5 dB)

3. Frequency Sweep Left Channel 800 Hz – 50 kHz. Log. 28 sec. Linear cut* (800 – 20000 Hz ±1,5 dB)

4. Frequency Sweep Right Channel 800 Hz – 50 kHz. Log. 28 sec. Linear cut* (800 – 20000 Hz ±1,5 dB)

5. Reference tone 1000 Hz 5 cm/sec rms Left

6. Reference tone 1000 Hz 5 cm/sec rms Right

7. Reference tone 1000 Hz 5 cm/sec rms Left

8. Reference tone 1000 Hz 5 cm/sec rms Right

9. Tracking ability, lateral 50 μm peak

10. Tracking ability, lateral 60 μm peak

11. Tracking ability, lateral 70 μm peak

12. Tracking ability, lateral 80 μm peak

13. Tracking ability, lateral 90 μm peak

14. Tracking ability, lateral 100 μm peak

15. Square Wave Form 2.7 msec duty cycle 3:7

* The record has a constant velocity amplitude throughout the sweep.

Introduction

Before testing your cartridge, please verify the HiFi system’s functionality. The left speaker should be connected to the left ampliﬁer

channel and vice versa; both speakers should work in phase and be optimally positioned in the room.

The Test Record is designed to be played through your system with in-built RIAA equalization. Volume control is recommended to

be set at a moderate signal level.

Please refer to your turntable and tonearm’s instructions for correct installation and alignment, adjust tonearm to be parallel to

record surface, set Vertical Tracking Force and antiskating according to the cartridge’s recommended technical data, and adjust

stylus overhang.

Azimuth adjustment or vertical alignment of the cartridge is very important for optimal channel separation.

The checking is easily done by lowering the cartridge onto a thin mirror placed on the record surface and examining whether the

reﬂection lines up square with the cartridge, when viewed from the front. During this test the tonearm must still be parallel to the

record surface. If not obtainable because of mirror thickness, remove record and work directly on the mat. To adjust, check the

manual for the turntable or cartridge.

1-4 Frequency sweep – a tool for

checking frequency response

There are several 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 cartridge loading, a better overall frequency response

can be achieved. Considering the above the signal must be

clean throughout the sweep.

5-8 Reference tone for testing channel output

With this standard reference signal it is possible to check the

correctness of the connections of the left and right channels, channel

balance and speed of the turntable.

9 -14 Tracking ability test, 315 Hz lateral modulation

These tracks contain a 315 Hz signal, recorded at increasing pick amplitudes of

50, 60, 70, 80, 90 and 100 micrometers. Please refer to your cartridge’s tracking

ability value speciﬁed in the technical data sheet. Your cartridge should be able to track

the actual level without audible distortion. Inability to track can be heard as a departure from

a pure tone or a sputtering and intermittent tone. To determine if it is one or both channels, the

balance control can be utilized. In case of differing tracking ability in the left and right channels it is

probably necessary to readjust the anti-skating correction of the tonearm. If both channels fail to track

properly, then vertical tracking force should be increased until no further improvement of tracking force can be

obtained.

15 Square Wave Form 2.7 msec duty cycle 3:7

When monitoring the output of your cartridge with an oscilloscope you’ll then see a square wave located precisely above each

other if the connection from the cartridge is correct.

Conclusion

After successful completion of the above test procedures, you can ensure that your cartridge is optimized. Still the human ear is

very sensitive to difference in tone distortion; its level depends on the stylus condition and record wear. To maintain optimal sound

reproduction and to minimize wear on your records as well as on your stylus, we recommend the following procedure before and

after each playback:

Remove dust carefully from record surfaces by using a ﬁne antistatic brush or cloth before every use.

Please remember to remove dust from the diamond tip before and after playback of each record.

In order to keep electrical contacts clean and to lubricate the knurled nut on the tonearm, Ortofon

recommends occasionally a light spray of contact cleaner like DeoxIT

®Gold G-Series into the

tonearm socket.

It should be noted that some phono equalizers may generate some tone distortion, which cannot be

referred to the cartridge.
