* The record has a constant velocity amplitude throughout the sweep.
Same program on both sides.
Each side of the record consists of 15 tracks which have been cut from 1-4 and 5-15.
No timings for tracks 5-15.
Tracks 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.
Tracks 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.
Tracks 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.
Track 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.
In order to ship your records to you in the safest way possible, and to avoid seam splits, we recommend removing the record from the jacket when shipping. That said, we will never open sealed records and do this without your permission. If you would like your records shipped to you this way, please request this in the notes section of checkout.

Darkside Records - How We Ship
Please review our shipping policy (link above) for information on our shipping rates and import fees.
All domestic Vinyl orders ship via UPS Ground (with the exception of PO Boxes, APO/FPO where we must choose USPS Priority) for a flat rate of $7.99 + $1 for each additional item. We take great care in our packaging to ensure orders arrive to you quickly and safely. Most orders are shipped within 24 hours of your order being placed (with some exceptions, e.g. post RSD when we have a massive influx of orders) and are packaged in Whiplash LP mailers that are specifically designed to protect your records. We use 100% recyclable packing materials, from paper tape to HexcelPack, to do our small part to cut out single-use plastics.
International Orders: Please note that we are not charging/collecting import fees/GST. These fees will be determined by your country upon entry of your package. Please keep this in mind when ordering that these extra fees will most likely apply. We know and agree that international shipping rates are incredibly expensive. Unfortunately at this time we do not feel that USPS is a reliable option for us to ship international orders so our prices exclusively reflect those of UPS. Please reach out to us with any questions.
