The address selection switch allows setting the ampli er’s network address,

EASY REMOTE

Easy Remote provides a simple way to remotely power-on/off the power amplier. The Easy Remote function is only useful for appliances not employing a RCM-24 Module. Controlling appliances with RCM-24 Module installed per Easy Remote is practically pointless.

EASY REMOTE IN

Leaving the pins of the EASY REMOTE IN socket open, i.e. when connecting +5V, the appliance power is switched on. When connecting the EASY REMOTE IN, i.e. when feeding 0V from the control output, the appliance enters standby mode.

EASY REMOTE SLAVE

The EASY REMOTE SLAVE connector provides connection for additional appliances with Easy-Remote function (e.g. for switching several devices within a rack-shelf ON/OFF). The switching of the slave-units is delayed to prevent the mains fuses from blowing.

POWER AMPLIFIER OUTPUTS

REAR VIEW

The STATUS LED provides optical indication of CAN-bus trafc. When the power amplier’s address is set to “00” so that it is separated from the CAN bus, the STATUS LED blinks every 3 seconds. As soon as CAN-bus communication is recognized, the LED is activated for at least 100ms whenever the power amplier actively sends data on the CAN-bus. The STATUS LED may also be activated from the PC. In this case, the LED of the according power amplier blinks fast and steady while all other status LEDs within the system stay dimmed.

4-pole binding-post terminals are provided for the power amplier channels „A“ and „B“. Two integrated audio output transformers convert the power amp’s nominal output voltage to 100V or 70V respectively. Depending on the conguration, the corresponding output voltage is present at the oating output terminals. The maximum amount of connected loudspeaker systems is reached when the

loudspeaker network’s total power consumption equals the power amplier’s nominal output capacity, without exceeding the power amp’s nominal load impedance. For further information on nominal output capacity and nominal load impedance, please refer to the “SPECIFICATIONS”.

Caution: During operation the binding-post terminals might carry high voltages. Therefore, installing

the loudspeaker network has to be in accordance with applicable safety regulations. Installation has to be carried out by accordingly trained professionals only. When installing and operating 100V PA-systems obeying the VDE-regulation DIN VDE 0800 is mandatory. Especially when 100V alarm PA-system installations are concerned, safety measures have to be in accordance with rating class 3. Before operating the power amplier closing the coverlid attached to the terminal strip is mandatory.

Choosing balanced cables (two conductors for the audio signal plus separate shielding mesh) with

XLR-type connectors is recommended for LF-signal connection. Although connecting unbalanced

cables to the power ampli er inputs is possible as well, using balanced cabling is always preferable. A

great number of today’s audio appliances employ balanced outputs. With balanced cabling, the shield

The network of the remote power amps is based on the CAN-bus standard, which for years is especially

for command and data transmission. Controlling the power ampli ers is performed from a PC with IRIS

all appliances. In general, it does not matter whether a participant on the bus is a power ampli er

or an UCC1 USB-CAN converter, so that

can be operated on a single CAN-bus. Since

the CAN-interfaces of all appliances are

galvanically separated from the rest of the

CAN-interfaces in the network are connected to a common ground potential. The UCC1 provides the
