Page 7: Safety Notes
VDE regulations against burn-up due to possible spark gaps. For greater safety and reliability all Hoellstern amplifiers feature an internal mains voltage monitoring and will cut out almost with no delay in case of a cable interruption. Hence spark gaps caused by disconnecting the mains supply will be avoided best or put out as quickly as possible. - Page 8 In the following cases it will be necessary to return the unit to the manufacturer or to a producer-authorised specialised company for inspection. You will find the contact data on the manufacturer's homepage www.hoellstern.com. - The unit was dropped or otherwise mechanically mistreated or damaged.

Page 9: Mounting Into A 19" Rack Or A 19" Cabinet
For manual function control and during the power-up phase the fans will momentarily run at a higher speed. Hoellstern amplifiers which offer several operating modes use different fan speed curves depending on their operating mode and the potential power output. -
Page 10: Balanced Input Signals
The output connections are made via Neutrik high-current SpeakON sockets. To keep the cable losses in the loudspeaker cables low and to ensure safety, we recommend using a cable cross section of 4 mm . Hoellstern amplifiers are equipped with scoop-proof high-current SpeakON sockets which have a very low contact resistance of typically 1milliohm per contact. -
Page 11: Configuration
A Hoellstern DELTA 4-channel amplifier contains two identical amplifier modules. Module 1: C 1 / C 2 and module 2: C 3 / C 4. Both modules are fed from a common power supply. A Hoellstern DELTA 2-channel amplifier contains one amplifier module. -
Page 12: Connecting Channels 1 To 4 (Amplifiers Produced Until 07/2011)
Connecting Channels 1 to 4 (amplifiers produced until 07/2011) Channels 3 and 4 are connected just like channels 1 and 2. Only the pictured wiring options are permitted. The wiring options are printed on the back panel of the unit. Alternatively, in bridge mode connector C2 pin 2+/ 1- or connector C4 pin 2+/ 1- can be used. -

Page 19: Indicators And Controls
Indicators and Controls Gain Controls Each amplifier channel has its own gain control on the front panel. In bridge/mono mode the C2 or C4 control has no effect on the gain. The gain controls are controlled and analysed by microprocessors. A change in the position will only be taken over with a short delay. -
Page 20: Power Supply
Power Supply Mains Supply and Power Supply with iCVP® Technology The devices feature an active power factor correction circuit (PFC). Therefore the amplifier will burden the mains supply almost like an ideal, purely ohmic load. This means that voltage and current flow are in phase. Only this way you can draw maximum power from mains with almost no reactive power. -
Page 21: Technical Specifications
ASID GmbH. The libraries are described and sorted by loudspeaker brands on the website. All DSP setups have been carefully compiled. The Hoellstern setups emulate precisely their originals in terms of transit time, phase and gain over the frequency. Likewise, the safety-relevant RMS and peak limiters have been carefully worked out. -
