ቦ CONTOUR switches provide three tapers for PGM 1 and
PGM 2 Program Faders. The numbers 6, 20 and 30
indicate the mid-point attenuation. Settings can provide
smooth fade or cut and scratch effects. Note from the graph
shown in Figure 2, that the 6 dB setting provides a quick on
contour for cut and scratch (0% travel is with Program Fader
up). When used with the HAMSTER reversal switch, the
Program Fader operates very similar to the Crossfader,
allowing the same hand motion for cut and scratch opera-
tion. The 20 dB setting provides a normal audio taper while
the 30 dB setting provides a more rapid fade out.
ቧ HAMSTER switches are provided for PGM 1 and PGM 2
Program Faders. These switches reverse the operation of
the adjacent Program Fader. When engaged, signal is off
with the Program Fader up, and maximum with the Pro-
gram Fader down.
ቨ PHONO / LINE source select switches are provided for PGM 1 and PGM 2. These are “clickless” switches suitable for
“transform scratch” applications. The switches are field replaceable and may be rotated in 45° increments. See Figure 4 on
page Manual-6 for rotation and replacement instructions.
ቩ Program Fader controls for PGM 1 and PGM 2 are ultra low noise, long-life, monorail devices. An ActiveFader™ design
completely isolates the control element from the audio, providing the highest reliability and performance. See page
Manual-6 for cleaning and replacement instructions.
ቪ PGM 1 and PGM 2 Meters provide true L+R Dual Mono indication of Post-Program Fader signal levels. Ten segment
resolution is provided with a one second peak hold indication. With the Program Fader set to maximum, the input GAIN
TRIM should be set to indicate an average level of about +4.
ቫ Crossfader control is implemented using Ranes’ proprietary ActiveFader™ design. As with the Program Faders, all
audio is isolated from the control element, greatly extending the life and performance of the control. See page Manual-6 for
cleaning and replacement instructions
ቭ CROSSFADER CONTOUR control allows adjusting the “shape” of the Crossfader response from a gentle curve for
smooth, long running fades, to the steep pitch required for top performance cut and scratch effects shown in Figure 3.
ቮ CROSSFADER HAMSTER control allows reversing the
operation of the Crossfader. With the combination of
ActiveFader™, CONTOUR control, and HAMSTER control,
the TTM 54 provides a level of flexibility and performance
previously unavailable.
