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.
CROSSFADER HAMSTER control allows reversing the operation of the Crossfader. With the combina-
tion of ActiveFader™, CONTOUR control, and HAMSTER control, the TTM 54i provides a level of flex-
ibility and performance previously unavailable.
PHONES LEVEL control adjusts the loudness of the Headphone output signal. Always start with the
LEVEL at minimum (CCW) and increase to a comfortable level with signal present and your headphones
on. is prevents tearing them off after you plug them in with the level set too high. is Headphone
Amplifier delivers very high sound pressure levels (SPL) into most headphones. Because of the high current
and low output impedance, never short one side to ground or short left and right together as is possible
with mono cup headphones. Note: Low power headphone stages typically use large resistors on their
outputs, which allow shorting, but prevent high power. e TTM 54i gives you high power but does
not allow shorting.
MASTER / CUE switch selects the HEADPHONES monitor source:
• Use MASTER to rehearse your performance. is signal is the same as that at the MASTER OUT, but is
not affected by the MASTER LEVEL control.
• Use CUE to monitor the Program Input signal, so you can “Cue” a signal before fading it in. is signal is
not affected by the Program Faders or Crossfader.
PHONES PAN control is only active when CUE is selected. is control allows you to PAN between
PGM 1 or PGM 2.
HEADPHONES jack provides a high current output, capable of driving headphones between 8 Ω and
600 Ω. Because the amplifier is capable of high current drive, it is important that the outputs are not
shorted together or to ground. Do NOT use single cup phones that short tip and ring.
MASTER LEVEL adjusts the MASTER OUTPUT level for both the balanced and unbalanced outputs.
