With the hardware machine, these controls enable compensation for any
tape frequency loss or head wear. Under hardware use, the Sync and Repro
playback heads are calibrated to normal operating standards and are nearly
identical when set correctly. However, they may be tuned incorrectly to
achieve a desired sound. Sync EQ and Repro EQ are used as filters to shape
the frequency response of the system in maintaining a flat response, but they
may be used on their own for high or low frequency adjustment.
Sync HF EQ
Adjusts the high frequency content when Path Select ( page 546 ) is set to
Sync. When Path Select is not set to Sync, the control has no effect.
Sync LF EQ
Adjusts the low frequency content when Path Select ( page 546 ) is set to Sync.
When Path Select is not set to Sync, the control has no effect.
Repro HF EQ
Adjusts the high frequency content when Path Select ( page 546 ) is set to Re-
pro. When Path Select is not set to Repro, the control has no effect.
Repro LF EQ
Adjusts the low frequency content when Path Select ( page 546 ) is set to Re-
pro. When Path Select is not set to Repro, the control has no effect.
Noise
The Noise controls allow the user to control the Hum and Hiss
elements found on the original hardware. Separate controls
for Hum and Hiss are available and each can be adjusted for
creative purposes.
Tip: Click the control label text to return to the Hum or Hiss
value to 0.
Hiss affects the signal at the tape head; Hum is added after the
tape circuitry. Hum and Hiss values default to comparative lev-
els found on the original hardware. The available range for
both controls is ±25 dB.
The global Noise Enable control ( page 550 ) must be ON for the Hum and
Hiss parameters to have any effect.
