These P-series amplifiers fully incorporate Yamaha's renown technological expertise, and offer high reliability, rock-solid stability, and superb acoustic characteristics--all in a trim, 2U-sized package. Features · With two types of input jacks (balanced XLR and balanced phone) and three types of output jacks (Speakon, 5-way binding post, and phone), the P series is suitable for a wide variety of applications and installed systems. · The unit offers three operating modes: STEREO (where Channels A and B operate independently), PARALLEL (where the unit outputs a mono source through twin amplifier systems), and BRIDGE (where the unit operates as a single high-power amp). · Each channel is equipped with an independent OFF/LOW CUT/SUBWOOFER switch--where LOW CUT engages a high-pass filter, and SUBWOOFER engages a low-pass filter. (The Channel B frequency controls are disabled. ) sleeve (ground) tip (hot) 7 4 STEREO/PARALLEL/BRIDGE switch Use this switch to select the operating mode. · STEREO mode Channels A and B operate independently (as with a conventional stereo amplifier). The Channel A input goes to the Channel A output jacks, and the Channel B input goes to the Channel B output jacks. · PARALLEL mode The Channel A input signal is output through both the Channel A and Channel B output jacks. · BRIDGE mode The Channel A input signal is output from the BRIDGE output jacks. To adjust the volume, you must use the Channel A volume control knob. 5 SPEAKER jacks Neutrik NL4FC Speakon output connectors, 5-way binding post output jacks, Phone output jacks For minimum speaker impedenance values, see page 9. 6 GND terminal This is a screw-type ground 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. 8 Speaker Connections Speaker impedance 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 speakers' impedance is not less than the relevant minimum value indicated below.
