teed you many years of troublefree amplification.
If you have to start using the HE50 straight away and do
not have the time to read the complete
manual, make sure that you at least read the following:
•
•
•
•
•
•
Ensure that you have a reliable, well earthed power source. The required current for
the HE50 can be found in the table in paragraph 3.1.
Connect the HE50 to your signal sources via the <INPUT> connectors. Connect this
amplifier to other units via the <LINK> outputs using short signal leads. Connect your
single signal source to the channel 1 input if you use the HE50
in
dedicated active presets.
Never make connections to the amplifier or to any preceding equipment with the ampli-
fier switched on!
Switch the HE50
on using the <POWER ON/OFF> switch.
S
For full-range operation at a 4 ohms load or higher please select preset 1 <2500 2500>
For full-range operation at a load below 4 ohms please select preset 2 <2000 2000>
elect the desired preset and input sensitivity by means of the <SELECT ROTATOR >.
The HE50 is now ready for use.

2 Introduction
The Stage Accompany HE50 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
64-bit 96kHz high quality DSP controller
2000W into 2 ohms.
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 HE50 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 HE50 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 HE50 has a number of features, including:
Class D operation.
DDC (Dynamic Damping Control).
Switched mode power supply.
Dual auto-negotiation RJ45 ports.
DSP processing.
Two channel AES/EBU input.
Soft start to reduce power on inrush current.
Temperature, DC, HF and short circuit protection.

DDC
DDC (Dynamic Damping Control) is a special way of measuring the cone movement of a
loudspeaker. The voltage induced in the voice coil is sensed and fed back to the amplifier’s
feedback circuit. Hence, a virtually infinite damping is achieved, which results in an exceptionally
tight sound production.
Soft Start
The soft start circuit is active when the HE50 is turned on. The mains inrush current, which
normally is in excess of 100 A is limited to a safe value. However, take care not to switch on
too many HE50 amplifiers at the same time, or you risk that the main fuses of your distribution
may trip.
Temperature, DC, HF and Short Circuit Protection
The amplifier and the loudspeakers are protected against all possible damages.

3 Connections
Only three connections need to be made: mains power, audio input signals, and loudspeaker
leads. Do not make any connections to the amplifier or to any preceding equipment with the

exact voltages are stated at the rear of the amplifier. Switching between mains voltages has to
done by an authorised Stage Accompany service centre. Connecting to the wrong voltage is
dangerous and may damage the amplifier. Always ensure that you use a correctly grounded
power supply. If more than one HE50 is to be used, it is advisable to connect each one
separately to the nearest mains supply in stead of connecting several HE50s using an adapter
block (see figure 3-1).

CONNECTIONS
This will prevent unnecessary power loss in the mains cables. If circumstances do not allow
this, it is advisable to connect the adapter block directly to the power supply using a short cable
and then connect the individual HE50s to it using longer leads. Although this method is not
ideal, it does limit power loss as much as possible.
Ultimately, it is possible to place the adapter block near theHE50s, but if a great deal of power
is required from the unit, the final current provided is far from optimum: loss of current leads to
unrecoverable loss of output power and therefore sound pressure.
Warning :
Always disconnect the HE50 from the power supply before operating on the fuse holders!
Replace a blown fuse only with a new one of the same type and value!
Current Table
Below, the current consumption of the HE50 is tabulated for two selectable mains voltages.
The power consumption shown applies 1/8 of maximum output power pink noise in 2 ohms, wich
is representative for typical music program with occasional clipping. If your speaker system has
an impedance of 4 or 8 ohms you may multiply the currents by 0.5 or 0.25.
The mains voltage may NOT deviate more than -20 % to +10 % of the nominal value. The
proportional mains voltage cable loss may not exceed 10 %. The following formula may be used
to calculate the maximum mains cable length in meters for 220-240 V models:
