• INPUT (LINE 1, LINE 2, LINE 3): RCA stereo input jacks for connecting external audio sources (e.g., CD player, mixer).
• OUTPUT (LINE 1, LINE 2, LINE 3): RCA stereo output jacks for connecting to other amplifiers or recording devices.
• DIRECT SPEAKER OUTPUT (COM, 4-16 Ohm, 70V, 100V): Terminals for connecting speakers. Use COM with 4-16 Ohm for low impedance speakers, or COM with 70V/100V for constant voltage systems.
• 70V SPEAKER ZONE OUTPUT (COM, Z1-Z6): Screw terminals for connecting 70V speakers to individual zones.
• POWER SELECT (110V/230V): Voltage selector switch. Ensure this matches your local power supply before connecting.
• AC IN: Power cord inlet.
• FM ANTENNA: Connection for the included FM antenna.

5. Setup

5.1 Placement

Place the amplifier on a stable, flat surface or mount it in a standard equipment rack. Ensure there is adequate ventilation around the unit to prevent overheating. Avoid placing it near heat sources or in direct sunlight.

5.2 Power Connection

1. Verify the POWER SELECT switch on the rear panel matches your local power voltage (110V or 230V). Incorrect selection can damage the unit.
2. Connect the provided power cable to the AC IN port on the rear panel and then to a suitable wall outlet.

5.3 Speaker Connections

The PAC360-6 supports both low impedance (4-16 Ohm) and constant voltage (70V/100V) speaker systems. Do not mix these types of connections on the same output terminals.

5.3.1 70V/100V Speaker Zone Output

This method is ideal for multi-room applications using multiple speakers. Ensure all speakers have a 70V or 100V transformer.

1. Connect the negative ends of your speakers to the 'COM' terminal on the 70V SPEAKER ZONE OUTPUT block.
2. Connect the positive ends of each speaker to the designated zone terminals (Z1, Z2, Z3, Z4, Z5, Z6) to create independent zones.
3. The total wattage of all connected speakers in a 70V/100V system should not exceed the amplifier's rated power (360W).

5.3.2 Direct Speaker Output (4-16 Ohm / 70V / 100V)

Use these terminals for direct connection to a single speaker or a series of speakers. Note that the 4-16 Ohm output does not have separate zone volume control.

1. For 4-16 Ohm speakers: Connect the negative speaker wire to the 'COM' terminal and the positive speaker wire to the '4-16 Ohm' terminal.
2. For 70V speakers: Connect the negative speaker wire to the 'COM' terminal and the positive speaker wire to the '70V' terminal.
3. For 100V speakers: Connect the negative speaker wire to the 'COM' terminal and the positive speaker wire to the '100V' terminal.

5.4 Input Connections

1. RCA Line Inputs: Connect external audio sources (e.g., media players, mixers) to the LINE 1, LINE 2, or LINE 3 RCA input jacks on the rear panel.
2. Microphone Inputs: Connect microphones to the MIC 1 or MIC 2 1/4-inch jacks on the front panel. MIC 1 has priority over other inputs.
3. FM Antenna: Connect the included FM antenna to the FM ANTENNA terminal on the rear panel for radio reception.

6. Operating Instructions

6.4 Microphone Usage

1. Connect your microphone(s) to the MIC 1 or MIC 2 inputs.
2. Adjust the MIC VOL knob to control the microphone volume.
3. Use the ECHO and DELAY knobs to add effects to the microphone signal.
4. Note that MIC 1 is a priority input, meaning it will automatically lower the volume of other audio sources when used.

6.5 Zone Volume Control

Each of the six zones (Z1-Z6) has an independent volume control knob on the front panel. Adjust these knobs to set the desired audio level for each specific zone.

6.6 Master Volume, Bass, and Treble

• MASTER VOL: Adjust this knob to control the overall output volume of the amplifier.
• BASS/TREBLE: Use these knobs to fine-tune the low and high frequencies of the audio output to suit your preference or room acoustics.
