POWER connector. is is not a telephone jack! Connect only the Rane RS 1 power supply included with your TTM 54i.
MASTER OUT includes two sets of stereo outputs:
• e ¼" TRS jacks provide high current BALanced output, which should be used whenever driving equipment with a balanced
input or running distances greater than about 10 feet (3 meters). Due to the high drive capability and low impedance, never use a
mono ¼" Tip/Sleeve (no ring) cable in this jack; this grounds one side of the balanced output.
• Use the UNBALanced output for shorter runs, such as connecting to a recorder, looping to another mixer, or to other local signal
processing or amplifiers.
EFFECTS jacks are unbalanced mono ¼" Tip/Sleeve. is stereo loop is inserted in the signal path as in section .
• e SEND jacks provide the output to your effects processor.
• e RETURN jacks provide an input for the signal returning from your effects processor.

PGM 1 and PGM 2 inputs include both PHONO and LINE input.
• PHONO 1 and PHONO 2 inputs are RIAA compensated inputs with 18 dB per octave, 20 Hz rumble filters.
• LINE 1 and LINE 2 inputs are unbalanced line level inputs with a nominal sensitivity of -10 dBV.
• PHONO/LINE selection is made as described in .
• PGM 1 inputs are sent to the left side of the Crossfader. (HAMSTER switch out)
• PGM 2 inputs are sent to the right side of the Crossfader. (HAMSTER switch out)

PHONO GND terminals provide an independent ground connect point for two turntables. It is very important that each turn-
table have a very good ground connection to one of these terminals. e thumb screws are not captivated, so use care not to spin
them off and lose them.
Important Note
CHASSIS GROUNDING
If your system exhibits excessive hum or buzzing, there is an incompatibility in the grounding configuration between units some-
where. Here are some things to try:
1. Check that the turntable grounding wires are connected to the PHONO GND posts (
22
).
2. Try combinations of lifting grounds on units that are supplied with ground lift switches or links.
3. If your equipment is in a rack, verify that all chassis are tied to a good earth ground, either through the line cord grounding pin or
the rack screws to another grounded chassis, or tied to the ground screw located just above the POWER jack.
4. is unit’s outboard power supply does not ground the chassis through the line cord. Make sure that this unit is grounded either to
another chassis which is earth grounded, or directly to the grounding screw on an AC outlet cover by means of a wire connected to
a screw on the chassis with a star washer to guarantee proper contact.
Please refer to RaneNote “Sound System Interconnection” (supplied with this manual and available at our web site) for further
information on system grounding.
