Rane TTM 54I User Manual
OPERATORS MANUAL
Quick Start
For experienced turntablists, ninety percent of
the operation of the TTM 54i Performance Mixer
is obvious — however, the TTM 54i also has many
unique features. ese new features will be mastered more
quickly if you read the entire manual. Right! We know some
of you can’t resist jumping right in, so please read at least this
portion of the manual. It will help you get a good start.
• GAIN TRIM: ese controls are intended to set the signal level
before the Crossfader. Always set the GAIN TRIM controls to
indicate an average signal level of +4 on the meter with the Program
Faders set to maximum. Never use the GAIN TRIM controls to set the
output level. Always use the MASTER LEVEL control to set the output
level. is is a very simple thing, yet makes a huge difference in the performance
of your mixer.

• EFFECTS: e assignable effects loop allows insertion of a stereo effects processor into:
• Pre-Program Fader PGM 1....... Engage PGM 1 EFFECTS only.
• Pre-Program Fader PGM 2....... Engage PGM 2 EFFECTS only.
• Post-Crossfader MASTER........ Engage both PGM 1 and PGM 2 EFFECTS switches.
• Read sections and for more information.
• PHONES: e headphone output of the TTM 54i is a high power output stage (unlike most you have used before). ere are
some notable differences…
• e headphone output of the TTM 54i delivers very high volume into your headphones.
• To avoid pain, never put headphones on your head and then plug them in.
• Always start with the PHONES LEVEL turned down and then turn it up to the desired level.
• 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.
• MIC LEVEL: For best performance, keep this control at 0 when not in use.
• For instructions on rotating Phono/Line switches to the desired location, see page Manual-6.
• Do not spray cleaner or lubricant into the front of the Program Faders or Crossfader. e fluid will just run out the bottom of
the unit. Never use unapproved cleaner or lubricants such as skateboard wheel lube, as corrosive damage may result, voiding the
warranty. See page Manual-6 for cleaning and replacement instructions and cleaner recommendations.
• Never connect anything except an RS 1 Rane AC power supply to the thing that looks like a telephone jack on the rear. is
is an 18 VAC center-tapped power unit. Consult the Rane factory for replacement or substitution.
• WEAR PARTS: is product contains the following wear parts subject to the ninety (90) day warranty period described on page
Warranty-1: FT 45 Crossfader & Channel Fader Assembly(3); ST 2 Phono/Line Switch Assembly (2).

PGM 1 and PGM 2 input GAIN TRIM controls adjust the input level. With the
Program Faders () at maximum, set GAIN TRIM to give a peak reading of +4 on
the meter. Set the MASTER LEVEL () to minimum while adjusting). It is always
best to run the input level at +4 to +7. Use the MASTER LEVEL to adjust the volume at the MASTER OUT ().
BASS and TREBLE controls provide deep cut, Accelerated Slope™ EQ for PGM 1
and PGM 2. is unique EQ design makes it possible to eliminate the “sizzle” or
“bass beat” without changing the vocal range. e graph in Figure 1 indicates the
response of the filters.
BALANCE controls are used for LEFT/RIGHT balance of PGM 1 and PGM 2 or
for LEFT/RIGHT Pan effect. Push the control to the left and sound moves to the
left channel. Push the control to the right and sound moves to the right channel.
EFFECTS engage switches are provided for PGM 1 and PGM 2. ese two switches
determine the location of a single, assignable, stereo EFFECTS LOOP.
• PGM 1 & PGM 2 EFFECTS both out: EFFECTS is not engaged.
• PGM 1 EFFECTS switch in only: EFFECTS inserted pre-Program Fader PGM 1.
• PGM 2 EFFECTS switch in only: EFFECTS inserted pre-Program Fader PGM 2.
• PGM 1 & PGM 2 EFFECTS both in: EFFECTS inserted post-Crossfader Master.
CONTOUR switches provide three tapers for PGM 1 and PGM 2 Program Fad-
ers. e numbers 6, 20 and 30 indicate the mid-point attenuation. Settings can
provide smooth fade or cut and scratch effects. Note in Figure 2, 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
operation. e 20 dB setting provides a normal audio taper while the 30 dB setting
provides a more rapid fade out.
HAMSTER switches reverse the operation of the adjacent PGM 1 and PGM 2
Program Faders. When engaged, signal is off with the Program Fader up, and
maximum with the Program Fader down.
PHONO / LINE source select switches are provided for PGM 1 and PGM 2. ese
are “clickless” switches suitable for “transform scratch” applications. e switches
are replaceable and may be rotated. See page Manual-6 for rotation and replacement
instructions.
Program Fader controls for PGM 1 and PGM 2 are ultra low noise, long-life,
monorail devices. e control element is completely isolated from the audio using
VCA circuits (voltage-controlled amplifier), providing the highest reliability and
performance. See page Manual-6 for cleaning and replacement.
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, set the input GAIN
TRIM to indicate an average level of about +4.
Crossfader is implemented using Ranes’ VCA 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.
