NOTE: it is normal for the Br Mono indicator LED to transition slowly. •STEREO MODE (Green LED). Each channel operates independently, as usual. •PARALLEL INPUT MODE (Orange LED). The inputs of both channels are hard-switched together, but all controls and speaker connections work as usual. Do not attempt to parallel the output channels to the same load. INPUT SENSITIVITY SWITCH, 3-POSITION: 26dB, 32dB, 1.2V •The 26dB (Orange) and 32dB (Green) settings provide the same voltage gain for all models. When using these settings, all models will sound equally loud, but the more powerful amp will have more headroom. •The 1.2V setting provides the same input sensitivity for all models. Larger amps will sound proportionally louder, with the same amount of headroom. •The resulting input sensitivities and gains for each model are shown in the Specs. SPEAKER CONNECTIONS – SPEAKONS •Ch1 provides “4-wire” access to both channels using the standard convention: Ch1 uses 1+, 1-, and Ch 2 uses 2+ and 2-. •Ch 2 provides “2 wire” access to Ch 2 only, using 1+, 1-. SPEAKER CONNECTIONS – BINDING POSTS •WARNING: use safe wiring practice as peak output voltages can be hazardous. AC POWER CABLE AND AC VOLTAGES. •PL3 Series amplifiers are configured for specific AC voltages. The products operate safely over the normal range of AC line variation but rated performance applies only at rated voltage. •Where regulations permit, products feature locking detachable cordsets, and are shipped with AC plugs suitable for the intended AC voltage (see Specs). 10 AC Mains Current Draw This table provides typical current draw for each model as a function of load and output power level. Units of measurement are amperes rms. NOTE! Current draw shown is for 120 VAC line. For 230 VAC models, multiply values shown by 0.5. •1/8 power (pink noise) represents typical program with occasional clipping. Use this rating for most applications. •1/3 power (pink noise) represents severe program with heavy clipping. •Full power (sine) is continuous sine wave driven at 1% clipping. * Burst mode only. Protective limiting will reduce long-term AC current Model Load Idle Current (Amperes) 1/8 Power Pink Noise BTU 1/3 Power Pink Noise BTU Full Power Sine Wave BTU PL325 8 ohms x 2 4 ohms x 2 2 ohms x 2 1.0 5.2 A 8.5 A 12.6 A 792 1387 2178 8.6 A 14.3 A 22.0 A 893 1981 3339 17.0 A 28.3 A 45.3 A 1204 2481 4942 PL340 8 ohms x 2 4 ohms x 2 2 ohms x 2 1.0 7.5 A 11.8 A 19.1 A 1150 2114 3495 13.3 A 21.1 A 31.6* A 1682 2864 5306* 25.9 A 43.5* A 68.6* A 2082 4253* 8601* PL380 8 ohms x 2 4 ohms x 2 2 ohms x 2 2.8 8.7 A 13.1 A 19.3 A 918 1355 1768 16.0 A 26.2 A 41.6* A 1101 1674 3278* 38.3 A 70* A 100* A 1853 3000* 6000* Rack Mounting and Dimensions Use four screws and washers to mount the amplifier to the equipment rack rails. To use the amplifier outside a rack, attach the self-adhesive rubber feet to the bottom. For portable, mobile, or other applications where the rack assembly may be moved, we strongly recommend supporting the rear of the amplifier. A rear rack ear kit is available from QSC’s Technical Services Group. Optional rack handles provide finger grips at each end, making lifting and setting into the rack more comfortable. 15.63” (39.7 cm) 17.30” (44.0 cm) 3.50” (8.9 cm) Specifications PL325 PL340 PL380 MAXIMUM OUTPUT POWER 1kHz, 1% clipping 8 ohms, both channels driven 500 800 1500 4 ohms, both channels driven 850 1250 2500 2 ohms, both channels driven 1250 2000 4000* 8 ohms, bridge mono 1700 2600 5000 4 ohms, bridge mono 2500 4000 8000* (*Burst mode testing required due to AC service current limitations) TYPICAL DISTORTION 20-3kHz, 3dB below clip, or 20-5kHz, 10dB below clip, or 20-20kHz, 20dB below clip 8 ohms 0.002-0.01% 0.002-0.01% 0.01-0.03% 4 ohms 0.005-0.01% 0.005-0.01% 0.03-0.06% 2 ohms 0.02% 0.02% 0.10% MAXIMUM DISTORTION 4-8 ohms 0.05% 0.05% 0.20% 20-20kHz, 1dB below rated power FREQUENCY RESPONSE 8 ohms 20-20kHz, +/-0.2dB, all models.
