Thank you for choosing a Stage Accompany Power Amplifier. Making this choice has guaran- teed you many years of troublefree amplification. If you have to start usin g the DS50 straight away and do not have the time to read the complete manual, make sure that you at least read the following: •...

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.
Page 8
100 A is limited to a safe value. However, take care not to switch on too many DS50 amplifiers at the same time, or you risk that the main fuses of your distribution may trip.
Always ensure that you use a correctly grounded power supply. If more than one DS50 is to be used, it is advisable to connect each one separately to the nearest mains supply in stead of connecting several DS50s using an adapter block (see figure 3-1).
Page 10
Warning : Always disconnect the DS50 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 DS50 is tabulated for two selectable mains voltages.

Maximum cable length as a function of the cable gauge and the number of DS50s supplied through the cable. Audio Connections The XLR connectors (analog audio, AES/EBU in and link) of the DS50 are wired as follows: Pin 1 = shield Pin 2 = normal phase (signal+ or “hot”) Pin 3 = inverted phase (signal- or “cold”)
DS50 USER MANUAL stage accompany Loudspeaker Connections Due to the DDC feature, the DS50 has 4 output terminals per channel instead of 2. The speakon connector is wired as follows: Pin 1+ = “hot” or Signal+ Pin 1- = “cold” or Signal- Pin 2+ = “DDC hot”...

SPEAKON NL4FC Figure 3-4 DS50 loudspeaker connection without DDC Warning ! Never short-circuit the DDC terminals, and never connect the signal+ output terminal to the DDC- terminal or vice versa (see figure 3-5). Since you are disabling the amplifier’s feedback network, signal gain will be almost infinite.
Page 15
When more speakers are going to be connected to one amplifier, split the output and DDC leads as soon as possible behind the output terminals of the DS50 (see figure 3-7 on this and figure 3-8 on the next page).

SPEAKON NL4FC Figure 3-8 Correct way of connecting several enclosures to the DS50 The amplifier can cope with any load of 2 ohms or higher. This means that you may connect a maximum of two 4 ohms, four 8 ohms or eight 16 ohms loudspeakers per channel in parallel.

4 Operation The DSP (loudspeaker management) part of the DS50 offers a wide range of tools for sound system design and setup. These tools can make your system more efficient and better sounding, but to get the best possible sound it is important to use these tools properly. The following section explains the various functions of the DS50.
EXIT 4.2.2 Input Selection The DS50 inputs are fixed. Input 1 is routed from the analog XLR-input of channel 1, channel 2 is routed from the analog XLR-input of channel 2, channel 3 and 4 are routed from the digital AES/EBU XLR-input on the backside of the DS50.
DS50 USER MANUAL stage accompany 4.2.5 High Pass Filter Adjust the High Pass Filter frequency by turning the rotary encoder. You can switch the high pass filter off by turning the rotary encoder down (counterclockwise) until the frequency passes 20Hz.
DS50 USER MANUAL stage accompany 4.2.7 Compressor The Compressor is a true RMS compressor. Turn the rotary encoder to set the threshold. Press the rotary encoder to select the parameters. The available parameters are: Threshold, Attack, Hold, Release, Ratio and Makeup Gain.
Set the delay time by turning the encoder. The delay time on the front will be shown in ms, by controlling the DS50 with StageControl the displayed unit can be changed between ms or s, mm or m, feet, inches, or mils.

The default password is “SA“. To lock the DS50 control panel Press the MENU button for 3 times, and the display wil show Acces level: Unlocked. Rotate the SELECT button (encoder) clockwise to Locked and press the SELECT button.
This document describes how to install and use the StageControl software on your computer for the Stage Accompany Digital Series amps. Installing StageControl gives you the possibility to remotely setup, monitor and update (firmware) your SA amp(s) from the Digital Series through USB or internet.

In addition, good earthing is necessary to prevent noise, hum and safety problems. Be sure that the DS50 is built into a space with sufficient circulation of fresh air. A tem- perature that is constantly too high leads to switching on and off of the thermal protec- tion and considerably reducing the lifetime of the amplifier.
The warranty period on all Stage Accompany products is five years from the date of the first consumer purchase, with the exception of: •...
