9 Clip limiter DESCRIPTION When the audio signal drives the amp 's output circuit beyond its power capability , the amp clips and flattens the peaks of the waveform. The clip limiter detects this and quickly reduces the gain to minimize the amount of overdrive.
Input filter DESCRIPTION The low-frequency (LF) filter rolls off signals below either 30 Hz or 50 Hz. This improves bass performance by limiting sub-audio cone motion, making more power available for the speaker's rated frequency range. The filter settings for each channel are controlled individually through the DIP switch settings shown.
11 FEA TURES & SETUP Modo de entradas paralelas ¿ QU É ES? El interruptor "Parallel Input" le permite operar el amplificador en modo paralelo, enviando la misma se ñ al hacia ambos canales sin necesidad de utilizar un cable tipo "Y".
12 FEA TURES & SETUP Bridge mono mode DESCRIPTION Bridged mono mode combines the power of both amplifier channels into one speaker load, resulting in twice the voltage swing, four times the peak power , and approximately three times the sustained power of a single channel.

14 FEA TURES & SETUP What are the differences among Stereo, Parallel Input, and Bridge Mono modes? STEREO MODE This is the "normal" way of using the amplifier , in which each channel is fully independent.
FEA TURES & SETUP BRIDGE MONO MODE This mode combines the full power capabilities of both channels into a single speaker system. The amplifier internally re-configures so that the drive signal is applied to both channels with the correct phase relationship.

CONNECTIONS CONEXIONES CONNEXIONS ANSCHL Ü SSE DA T APORT The amplifier features a DataPort (page 8, item #1) which connects to accessory products to enhance your amplifier application. The CM16a Amplifier Network Monitor can remotely control and monitor your PL2 amplifier .
23 OPERA TION AC power switch Before applying power , check all connections and turn down the gain controls. The "soft start" sequence starts with the POWER indicator LED at half brightness. A few seconds later the fan starts, the POWER indicator fully illuminates and the amplifier mutes for two seconds.
Security panel After setting the gain controls, you can install the security panel to prevent tampering and accidental misadjustment. After the knobs have been removed and the gain setting checked, install the security panel as shown in the general illustration to the left and on next page.

30 TROUBLESHOOTING Problem: no sound • Indication: POWER indicator not lit • Check the AC plug. • Confirm that the AC outlet works by plugging in another device. If too many amplifiers are used on one outlet, the building's circuit breaker may trip and shut off power .
No sound (continued) TROUBLESHOOTING Pas de son (suite) • INDICA TION: DEL DE SIGNAL FONCTIONNENT NORMALEMENT • Si les DEL SIGNAL , -20dB et -10dB fonctionnent normalement, le probl è me se situe entre la sortie de l'amplificateur et le haut-parleur .
32 • INDICA TION: CLIP INDICA TOR NOT FLASHING • This could be caused by a faulty speaker or loose connection. Check the wiring and try another speaker . • The signal source may be clipping. Keep the amplifier gain controls at least halfway up so that the source does not have to be overdriven.
Problem: hiss • Unplug the amplifier input to confirm that the hiss is coming from the source or a device upstream; erratic or popping noises indicate an electronic fault in the offending unit.
34 INNER WORKINGS An impressive amount of technology is packed "under the hood" of a PL2 Series amplifier . Thousands of watts of power flow inches away from state-of-the-art low noise inputs. Precise circuit layout and thorough protection assure that all of this activity occurs smoothly and safely .
High Performance Audio . High speed power transistors convert this DC power into the full range audio output which drives the speakers. High-current design and special dual-sense output feedback corrects errors on both sides of the speaker terminals, improving damping and control of speaker motion.
