Manual-3
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. This prevents tearing them off after you plug them in with the level set too high. This 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. The 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. This 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. This signal is
not
affected by the
Program Faders
or
Crossfader
.
PHONES PAN
control is only active when
CUE
is selected. This 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.
