2 Introduction
The Stage Accompany DS50 is a dual channel, digital power amplifier and comprimises the
following components:
•
Balanced input stages.
•
Two digital amplifiers wich deliver each 1600W into 8 ohms, 2500W into 4 ohms and
2000W into 2 ohms.
•
64-bit 96kHz high quality DSP controller
•
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 25 kohms, it is posible to connect
a maximum of 30 DS50 amplifiers to a 600 ohms source like a mixing console. If more than
30 units need to be connected to a single source, a seperate signal driver must be used.
The DS50 is protected against the connection of speaker impedances less than 2 ohms or even
short circuiting of the output. In this fault condition the power supply lines to the amplifier
module will be interrupted.
The DS50 has a number of features, including:
•
DSP processing.
•
Two channel AES/EBU input.
•
Dual auto-negotiation RJ45 ports.
•
Switched mode power supply.
•
Soft start to reduce power on inrush current.
•
Class D operation.
•
DDC (Dynamic Damping Control).
•
Variable speed DC fan.
•
Temperature, DC, HF and short circuit protection.
