Connecting The System; Interconnecting Two Or More Systems - Ecler DPC7000 D Manual De Instrucciones

3.4. Connecting the system

Connection to the acoustic cabinet. This connection must be done with, at least, 3mm cable (we
recommend 6mm). The amplifier output and the acoustic cabinet input connectors are 4 pin SPEAKON
(see diagram A). The mid-treble cabinet will be connected as follows:
Treble +
Treble -
Mid +
Mid -
The bass reinforcement cabinet only uses pin 1+ and pin 1-.

3.5. Interconnecting two or more systems

With one single DP300 base unit you may interconnect up to 10 DPC7000 PC/DC systems
(complementary unit without processor). You just have to use the Stack outputs found on any amplifier.
These Stack outputs should be connected to identical amplifiers. IMPORTANT: The successively
interconnected amplifiers must be adjusted with identical settings as the amplifiers which are directly
connected to the DP300.
Another option is to use complete DPC7000 systems configured as master or slaves, depending
on the functional requirements. For that purpose we have designed the EPP LINT and EPC AINT
multicore, which let you interconnect several DPC units, configuring them as master or slave. The
master system will inhibit all the system associated processors. (See diagram B/C)
A set of small switches placed at the left side of the EPP LINT circuit board help you to use one
system for different configurations when stacking systems. It is for instance more convenient to use each
power amplifier rack in mono mode when working with even numbered systems (2, 4, 8...) (see diagram
B).
On the other hand, when working with odd numbered systems (3, 5, 7, 9...), one system would
operate in stereo (MASTER system) and the rest in mono mode (see diagram C).
Following this advice will in both cases minimise cable runs, as each power amplifier rack can be
placed next to the speakers, which is the most recommendable situation.
