Greetings Peter! excellent frequency response result! I have a reference speed and detonation cassette, 4.76 cm/sec 3150 Hz. 0.025% (DIN) The tape was recorded on special equipment, "Studer" with quartz speed stabilization! The tape was recorded in 1991 and it's new! But by the way, Tascam 112 mk2 has fairly stable speed indicators, so you can measure a tape length of 4.76 cm × 100 seconds = 476 cm, or 480 cm from leader to leader and record any signal from 300 Hz to 1000 Hz and this the signal must travel exactly 100 seconds during playback! Record it on your computer and run the test several times and it will be the most accurate test! Well, of course, you need to warm up the engine on the Tascam 112 mk2, about 30 minutes. Then you can use the same Tascam, a signal of 3000 or 3150 Hz. and there will be a test tape of our own production!👌👍
