            CABLING

LF-CONNECTION CORDS 

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 amplifier 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 connects all metal enclosure parts and thus efficiently eliminates the introduction of noise and 
hum

REMOTE CONTROL NETWORK

The network of the remote power amps is based on the CAN-bus standard, which for years is 
especially popular in automotive, industrial and security applications. The CAN-bus is a balanced 
serial interface for command and data transmission. Controlling the power amplifiers is performed 
from a PC with IRIS – Intelligent Remote & Integrated Supervision – software installed. The UCC1 
USB-CAN Converter serves as interface between the PC and the CAN-bus. Connecting up to 100 
power amplifiers per CAN-Bus with a maximum total cable length of 1,000 meters is possible. An 
additional CAN-bus is needed for controlling more than 100 power amps while the IRIS software allows 
administering a total of 250 power amps.
The network topology used by the CAN-bus is the so-called “bus or line topology”, i.e. all participants 
are connected via a single two-wire cable (Twisted-Pair cable, shielded or unshielded) with the cabling 
running from one participant on the bus to the next, allowing unlimited communication among all 
 

 

 

 

 

 

 

appliances included. In general, it does not 

 

 

 

 

 

 

 

matter whether a participant on the bus is a 

 

 

 

 

 

 

 

power amplifier or a UCC1 USB-CAN 

 

 

 

 

 

 

 

converter, so that both – UCC1 and the PC 

 

 

 

 

 

 

 

as well – can be inserted at any position. 

 

 

 

 

 

 

 

Incorporating several UCC1 and PCs 

 

 

 

 

 

 

 

on a single CAN-bus is also possible. A 

 

 

 

 

 

 

 

total of up to 100 appliances can be operated

 

 

 

 

 

 

 

on a single CAN-bus. Since the CAN-

interfaces of all appliances are galvanically separated from the rest of the circuitry, network cabling 
also carries a common ground conductor (CAN_GND) ensuring that all CAN-interfaces in the network 
are connected to a common ground potential. The UCC1 provides the possibility for switching the 
CAN-ground to circuit-ground.

Each participant on the bus system has two RJ-45 connectors for the Remote CAN-bus. These sockets 
are connected in parallel to serve as input and output (for connecting through) for the data transfer of 
the remote-network. The CAN-bus has to be terminated at both ends using 120 terminator plugs, two 
of which – CAN-TERM 120 – are supplied with the UCC1. Connect one of these to the RJ-45 socket 
of the first and the other to the socket of the last appliance on the CAN-bus
