Bosch PLE-1P120-EU Installation And User Instructions Manual

The PLE-1P120-EU and PLE-1P240-EU are two high-power plug-and-play cost effective power amplifiers that deliver 120 and 240 Watts to constant voltage or 8 ohm loads. Built with premium quality and protections, they offer basic functionality at a budget price. The amplifiers offer straight 1 V and 100 V line in, and 70 V, 100 V and 8 ohms out. They can extend the power of the PLE- series mixer amplifiers or be combined with the PLE-10M2-EU mixer, or work anywhere where more power on an existing 100 V line is needed or when a line level signal is provided. Functions Protection The amplifier is protected against overload and short circuits. A limiter protects the amplifier and loudspeaker against accidental overdriving. A temperature-controlled fan ensures proper cooling without producing acoustic noise at lower output levels. Power input and output The unit operates both on mains power and on a 24 V battery power supply for emergency back up, with automatic switchover. The amplifier also has a built‑in charger to charge the connected battery. The system has a balanced input and loop‑through facility. This makes it easy to connect multiple amplifiers. The secondary input is a 100 V line input to connect the amplifier to a 100 V loudspeaker line to provide more power in remote locations. Gain or level control is located on the rear of the unit to avoid accidental setting change. A meter with LED bar shows the output level. The amplifier has a 70 V or 100 V output for constant voltage loudspeaker systems, and a low impedance output for 8 ohm loudspeaker loads. Controls and indicators Front • Power on LED • LED VU meter for master output (LEDs for -18, -12 -6, -3, 0 dB) • On/off button Back • Level control Interconnections See Technical Specifications.

Plena Power Amplifier | Installation and User Instructions | Description en | 7 2 Description 2.1 The Plena product range The Plena Easy Line Power Amplifier is part of the Plena product range. Plena provides public address solutions for places where people gather to work, worship, trade, or relax. It is a family of system elements that are combined to create public address systems tailored for virtually any application. The Plena product range includes: • mixers • preamplifiers • power amplifiers • a music source unit • a digital message manager • a feedback suppressor • call stations • an All-in-One system • a voice alarm system • a timer • a charger • a loop amplifier The various elements are designed to complement each other thanks to matched acoustical, electrical and mechanical specifications. 2.2 Contents of box The packaging box contains the following contents: • PLE-1P120-EU, or PLE-1P240-EU • Power cord • Mounting brackets (LBC 1901/00) • XLR cable 2.3 The Plena Power Amplifier The Plena Power Amplifier is a high performance power amplifier for use in professional public address systems. For a schematic overview of the Plena Power Amplifier, see figure 2.1 on the next page. The Plena Power Amplifier is provided with one line input with a loop through output. A 100 V slave input gives connection to existing loudspeaker lines. This input is converted to 1 V and fed to the input. The 1 V and 100 V input is summed. The Plena Power Amplifier has 70 V and 100 V constant voltage output and a low impedance output for 8 Ohm loudspeakers. The Plena Power Amplifier has an overload and a short- circuit protection. A temperature controlled fan and overheat protection ensures high reliability. An LED meter monitors the master output. This signal is also present on the headphone socket below the output level meter. For total reliability and ease of use, a limiter is integrated into the output stage to restrict output if the user applies too much signal.

Plena Power Amplifier | Installation and User Instructions | Description en | 8 The unit has 24 VDC backup input with built in 24 VDC battery charger. A separate battery charger is, therefore, not required. The charger charges the battery with a 0.5 A constant current until the battery voltage reaches 27.4 VDC. The charger then switches over to constant voltage charging (also known as float charging). Note When using the unit with backup power of 24 V, make sure that the unit is always powered ON. When the unit is switched OFF, the batteries will be drained as this will be regarded as a power source. Consequently the unit will revert to 24 VDC power from the 24 V input. figure 2.1: Schematic overview of the Plena Power Amplifier 100V Input 1V Loop through Sensitivity Temperature controlled fan Limiter 100 V 8 Ohm 70 V 0 V

If you mount the unit in a rack, you must: • ensure that it does not exceed the overheating temperature (55 °C ambient). • use the included Bosch mounting brackets (LBC 1901/00). • remove the 4 feet from the bottom of the unit. 3.3 Check settings/connections 1 Connect any additional equipment (see section 4.1 and 4.2). 3.4 Connect unit to mains 1 Make sure the voltage selector (115/230 VAC) is correctly set for the country’s main voltage (see figure 3.2). 2 Make sure the power button on the front of the unit is set to Off. 3 Connect the power cord to the mains connector and plug it into the mains outlet. figure 3.1: Installing the unit in a rack 1 B Caution Potential equipment damage. Before connecting power, always check the voltage selector on the rear panel of the unit. figure 3.2: Power connection and voltage selector

Plena Power Amplifier | Installation and User Instructions | Connections and settings en | 13 4 Connections and settings 4.1 Connecting inputs 4.1.1 DC supply (battery) The Plena Power Amplifier has a 24 VDC input (terminal screw). This input can be used in mobile applications, such as boats where 115 or 230 VAC is not available or in applications that must continue to operate in case of a power failure. When a 24 VDC battery is connected (typically consisting of two 12 VDC lead-acid batteries in series), the unit will operate on the supplied DC voltage. The Plena Power Amplifier has as a built in charger, which charges the connected battery (or batteries if connected in series). A separate battery charger is, therefore, not required. The charger charges the battery with a 0.5 A constant current until the battery voltage reaches 27.4 VDC. The charger then switches over to constant voltage charging (also known as float charging). This means that a battery can be charged at the same rate it is discharging, and thus full capacity battery can be assured. This type of charging is suited for low duty-cycle applications where a relatively high current or power is infrequently required. Caution The connection cable must have an in-line fuse. Use the type of fuse shown in the following figure. Caution Make sure the unit is earthed. Note If the backup power system has to comply to the EN54-4 standard or similar standards for backup power and charging speeds, Bosch recommends the PLN-24CH10. The PLN-24CH10 is a dedicated battery charger and power supply that is fully EN54-4 compliant. figure 4.1: Connecting a DC power supply 12 VDC 12 VDC - + - + FUSE

A 100 V input signal can be connected to the Euro style pluggable screw terminal connector (2) at the rear of the unit as shown in figure 4.2. To adjust the volume of the input signal, turn the input volume control (4) at the rear of the unit. figure 4.2: Connecting a 100 Volt input signal

The 100 V connection in shown in figure 4.3. Connect the loudspeakers in parallel and check the loudspeaker polarity for in-phase connection. The summed loudspeaker power should not exceed the rated amplifier output power. 4.2.2 Low impedance loudspeakers Connect low impedance loudspeakers to the 8 Ohm/0 terminals. This output can deliver the rated output power into an 8 Ohm load. Connect multiple loudspeakers in a series/parallel-arrangement to make the combined impedance 8 Ohm or higher. Check the loudspeaker polarity for in-phase connection. figure 4.3: Connecting speakers figure 4.4: Connecting speakers
