3HPF 20 switches These switches are used to turn on and off the HPF (High Pass Filter) for each channel. When set to ON, frequencies below 20 Hz are filtered using a 12 dB/ octave high pass filter. 8 9 4SPEAKERS jacks • These are Speakon type output jacks. Speakon type cable plugs can be connected here. • These are five-way binding post output jacks. 5DATA PORT jack An amp control device, such as the ACD1 or ACU16-C, can be connected to the DATA PORT jack for monitoring or controlling the amplifier from the external device. 6AMP ID switch When an amp control device, such as the ACD1 or ACU16-C, is connected to the DATA PORT jack 5, the AMP ID switch can be used to set the amplifier’s ID. 7Euroblock connector This is a balanced input jack. The included Euroblock connector can be used to make connections here. 8AC inlet Connect the socket of the included AC cable to this inlet. Connect the plug of the AC cable to an AC outlet that meets the power supply conditions printed below this inlet. 9GROUND Screw terminal If you are having a problem with hum or noise, use this terminal to connect to ground or to connect to the chassis of the mixer, preamp, or other device in your system. ¦ ¦ Speakers can be connected to the amplifier as shown below. Note that speaker impedance will vary according to the connection method and the number of speakers. Please be sure that your speaker’s impedance is not less than the relevant minimum value indicated below. Connection configurations for STEREO and PARALLEL modes When using 5-way binding post output jacks When using the Speakon connector or Minimum speaker impedance: 4 . Minimum speaker impedance: 4 . Minimum speaker impedance: 4 . Minimum speaker impedance: 4 . Connection configurations for BRIDGE mode When using 5-way binding post output jacks When using the Speakon connector Minimum speaker Minimum speaker impedance: 8 . impedance: 8 . When connecting high-impedance speakers in parallel (PC3301N only) The number of speakers that can be connected varies depending on the rated input of the speakers. The PC3301N can be connected to speakers with a total rated input of up to 625 W. For example, if you connect five speakers with a rated input of 5 W (25 W), thirty speakers with a rated input of 10 W (300 W) and twenty speakers with a rated input of 15 W (300 W), the amplifier can be used with a total rated speaker input of 625 W as shown below: CAUTION Be sure to use speakers that support the PC3301N’s line-out voltage of 100 V. 5W 10W 15W 5 1 30 1 5 W x 5 speakers (25 W) 10 W x 30 speakers (300 W) 1 20 5W 10W 15W 15 W x 20 speakers (300 W) Total rated input of speakers: 625 W (maximum) Connection ¦ Using a Euroblock connector If cables will be frequently connected and disconnected, as in the case of a portable installation, we recommend that you use ferrules with insulation sleeves. Use a ferrule whose conductor portion has an external diameter of 1.6 mm or less, and a length of approximately 7 mm (such as the AI0,5-6WH made by the Phoenix Contact corporation). 1. If the wire insertion ports are closed, turn the screws on top of the connector counterclockwise to open the ports. 2. Insert the wires into the appropriate ports, following the indication of the pole on the input terminal, turn the screws on top of the connector clockwise to fix the wires. 3. Attach the Euroblock connector to the input terminal on the Use a screwdriver to fix the wires. unit. ¦ Speaker Connection 5-way binding post 1. Turn off the POWER switch. 2. Remove the cover attachment screws and remove the protective cover from the speaker terminals. Screw 3. Remove about 15 mm of insulation from the end of each speaker cable, and pass the bare wire through the holes in the appropriate speaker terminals. Tighten the terminals to securely clamp the wires. Refer to page 8 for speaker polarities. 15mm* * Actual size Speaker cable Be sure that the bare wire ends do not jut out from the terminals and touch the chassis. The following shows how the cable should look when correctly attached. Chassis Bare wire Note to users in the USA: Please use Class 3 wiring. (PC9501N, PC6501N, PC4801N) Please use Class 2 wiring. (PC3301N, PC2001N) 4. Reattach the protective cover over the speaker terminals. Speakon connector 1. Turn off the POWER switch. 2. Insert the Neutrik NL4FC plugs into the Speakon connector on the rear of the amplifier, and turn clockwise to lock.
