(5)-2 2/2 Introduction Thank you for purchasing a Yamaha PC9501N, PC6501N, PC4801N, PC3301N, or MK-100 Series Power Amplifier. The PC Series of power amplifiers was developed from Yamaha's wealth of experience in building PA equipment and its tradition of careful attention to every detail of circuit design. These power amplifiers feature high power and superb quality together with superior reliability and stability, guaranteeing the highest possible audio performance. Main features include · Three modes are provided to support a broad range of applications: STEREO mode which can be driven by two independent sources, PARALLEL mode in which a monaural source drives both channels, and BRIDGE mode in which the two internal amps function as a single mono amp. · Balanced XLR connector and Euroblock connector inputs, and Speakon connector and five-way binding post outputs are provided. · A high pass filter switch that cuts frequencies below 20 Hz, and detented attenuators and level meters for channels A and B are provided. · Metering and indicators include easily visible two-channel level meters, a PROTECTION indicator that shows the state of various protection systems (power on/off detection, output protection, DC detection), a TEMP indicator that indicates heat sink overheating, and a REMOTE indicator that indicates the external remote status. · PARALLEL mode In PARALLEL mode, the channel A input signal will be sent to the channel A power amp and to the channel B power amp. · BRIDGE mode In BRIDGE mode, channels A and B will operate simultaneously, functioning as a single mono amp. 7 Euroblock connector This is a balanced input jack. The included Euroblock connector can be used to make connections here. 8 AC 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. 9 GROUND 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. 3 HPF 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. 7 Speaker connections 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 impedance: 8 Minimum speaker 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. 1 5W 5 5W 1 10W 30 10W 1 15W 20 15W 5 W x 5 speakers (25 W) 10 W x 30 speakers (300 W) 15 W x 20 speakers (300 W) Total rated input of speakers: 625 W (maximum) 8 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). Use a screwdriver to fix the wires. 1. If the wire insertion ports are closed, turn the screws on top of the connector counterclockwise to open the ports. [. . . ] The wire which is coloured BROWN must be connected to the terminal which is marked with the letter L or coloured RED. · This applies only to products distributed by Yamaha-Kemble Music (U. K. ) Ltd. (3 wires) This mark indicates a dangerous electrically live terminal. When connecting an external wire to this terminal, it is necessary either to have "a person who have received appropriate guidance on handling" make the connection or to use leads or a cord that have been manufactured in such a way that the connection can be made simply and without problem.
