2 Introduction
The Stage Accompany ES 10 is a dual channel, high efficiency power amplifier and comprises
the following components:
•
Balanced input stages.
•
Two high efficient amplifiers which deliver each 290 Wrms into 8
Ω
, 430 Wrms into 4
Ω
and 530 Wrms into 2
Ω
or 340 W peak into 8
Ω
, 540 W peak into 4
Ω
, and 710 W peak
into 2
Ω
.
•
Advanced protection circuits.
The audio inputs and link outputs are connected internally without electronics. This is done to
prevent any loss of sound quality. With an input impedance of 22 k
Ω
, it is possible to connect
a maximum of 30 ES 10s to a 600
Ω
source like the SA 1310 graphic equaliser. If more than
30 units need to be connected to a single source, a separate signal driver must be used.
The ES 10 is protected against the connection of speaker impedances less than 2
Ω
or even
short circuiting of the output. In these cases the output current is limited but the amplifier keeps
working.
The ES 10 has a number of features, including:
•
High efficiency class G operation.
•
Variable speed DC fan.
•
DDC (Dynamic Damping Control).
•
EFN circuit (Extended Function Network)
•
Soft start to reduce power on inrush current.
•
Temperature, DC, HF and short circuit protection.
Class G operation
The power supply of the ES 10 amplifier produces 2 different supply levels. Each channel
actually consists of two power amplifiers. One produces the output signal, the other one selects
the power supply voltage. This way, the ES 10 uses the low level supply at low output power
and the high level supply at high output power which reduces internal dissipation significantly.
