1 Preface The Audionet Team congratulates you on your purchase of this unit. Audionet's latest amplifier AMP VII gives you the chance to combine all power amplifiers of your home cinema in one cabinet. Equipped with up to 7 separate channels, the AMP VII renders possible even modern 7.1 home cinema with only one amplifier unit. And you might as well expand existing stereo or multichannel systems due to its modular design and configurable number of amplifier modules.
1.1 Included Included you will find the following items: · the modular multichannel power amplifier AMP VII · the user's manual (that you are currently reading) · two standard mains cords 1.2 Transport Important · Please transport the AMP VII only in the included package. · Always use the plastic bag to prevent scratches on the housing. · Please allow the AMP VII to adapt to the climatic conditions in your listening room before you switch on the unit for the first time after transport.

4 Installation and power supply Important · For connecting or removing loudspeakers and/or the pre amplifier your AMP VII must be switched off to prevent damage to the amplifier or the connected units. · Please make sure that all cables are in absolute best conditions! Broken shields or short-cut loudspeaker cables could damage speakers and/or amplifiers. 4.1 Placement The compact design of the AMP VII requires the unobstructed heat dissipation during operation.
Important · Always use both mains connections. · The electrical specifications of your home country must meet the electrical specifications printed onto the back panel. · The AMP VII is a Class I unit and must be earthed. Please ensure a stable earth connection. Phase ('hot' pin) is marked 'phase' ( 22 and 24 ) on the back panel for each mains input. · If you connect the mains cords please make sure that the mains switch on the bottom of the unit (see section 'Frontpanel' on page 7) is switched off.
if the mains plug to mains input mains2 25 has the wrong orientation. In this case please switch off the unit with the power key to stand-by mode. Then disconnect it from mains with the mains switch on the bottom side. Now, flip the mains plug with the wrong orientation in the wall outlet (see section 'Mains phase detection' on page 14).
Note · Look out for the correct connection of your speaker cables. Usually the terminals of your speakers are marked '+' and '-'. The AMP VII uses the same marks. · Wrong speaker polarization will result in severe loss of sound quality! Important · Although the AMP VII has an effective protection system to prevent damage to the circuits, switch off the unit while working on the speakers and/or audio cables. · The nominal loudspeaker impedance should be 2 Ohms or higher.
6 Operating 6.1 Powering up First of all, please make sure your AMP VII is connected correctly to your pre amplifier, speakers and mains (see section 'Installation and power supply' on page 9 und Section 'Inputs and outputs' on page 11). The AMP VII is a stand-by unit. Please operate the mains switch on the bottom side. The display shows for a brief moment a welcome message. After that the AMP VII is in stand-by mode.
completely. The unit is now in stand-by mode, and the display shows the selected stand-by text (see section 'Set Off-Text' on page 22). Note · Please wait until the end of the discharging process, before you switch on the AMP VII again by pressing the power key on the front panel. 6.3 Mains phase detection The correct polarization of mains is important for reasons of audio clarity and stability.
6.4 Using Audionet Link If your AMP VII is connected to an Audionet pre amplifier via 'Audionet Link', use the remote control of the pre amplifier to automatically switch on/off the AMP VII (and all other units connected via 'Audionet Link'). For setting up the necessary connections please refer to section 'Audionet Link' on page 12.
minutes in steps of 15 min. The following diagram explains the possible countdown timer settings: 01 hour 15 min 01 hour 15 min 01 hour 15 min 11 hours 15 min 02 hours 15 min 01 hour 30 min 91 hours 15 min 00 hours 15 min 01 hour 00 min 10-hours setting 1-hour setting minutes setting long keystroke short keystroke Activate the countdown timer by leaving the timer setup menu with a long keystroke.
7 Protection system Your Audionet AMP VII protects your loudspeakers and itself with a complex protection circuitry. In case of a malfunction the display informs the user about the nature of the detected error in plain text. Furthermore, the unit also reports which module caused the error. Example: DC VOLTAGE IN: Amp Module No. 5 This means a 'DC Voltage' error was detected in module no. 5.
8 Setup menu Beyond the feature of the 'Warm Up Countdown' you can adjust the AMP VII to your preferences using the setup menu.
The following diagram gives an overview of the structure of the setup menu. The subsequent sections explain all options of the setup menu in detail.
8.1 Set Dim Level Select the brightness of the display on the front panel. Five steps are available: 100%, 75%, 50%, 25% and OFF. Important · Long-term usage of the display set to a maximum brightness (setting 100%) may cause extended signs of wear resulting in a decay of contrast or brightness of individual dots in the display.
Note · In case of thermal overload the AMP VII will always switch off independently from the display setting. · The temperature display mode gives the user a clue about the thermal load of the AMP VII. It depends on the placement, air flow and cooling, surrounding temperature and the number of installed modules in the AMP VII. Nevertheless, the full musical performance is achievd even if the display reports Temperature Cool. 8.
Tip Pinning of the balanced (XLR) inputs: 1: Ground 3: Negative 2: Positive The pins are marked with the same number as in the diagram above. 8.4 Set AutoStart If the AutoStart function is active, the AMP VII starts up automatically to normal operating mode right after the unit is connected to mains power (e.g. by operating the mains switch on the bottom side). Use this option to start up the AMP VII automatically using a timer device. disabled The AutoStart function is disabled.
Note · Approx. every 12 seconds the stand-by mode indicator changes position randomly in the display to prevent any 'burnin' effect (see section 'Set Dim Level' on page 20). 8.6 Overview factory defaults Option Einstellung SET DIM LEVEL 50% SET DISPLAY Standard SET INPUT Line (Cinch) SET AUTOSTART disabled SET OFF-TEXT dot Note · The Warm Up countdown is preset to 1 hour and 15 minutes, but deactivated (see section 'Warm Up countdown' on page 15).
9 Technical information 9.1 Design To optimize the high frequency properties the circuitry was consequently miniaturized and SMD technology implemented. Signal path ways are limited to a minimum length and contain no componets harmful to the quality of sound like coupling capacitors, coils or relays. The construction is optimized magnetically and capacitively. Influences of interferences and interaction between amplifier stages are extensively ruled out.
10 Security advice Important · Avoid packaging material, especially plastic bags, coming into children's hands! · Store and operate the unit in a dry room at a reasonable room temperature only! · Avoid moisture, any liquids, dirt or small objects getting into the unit! · Set up the unit in a sufficiently ventilated environment! · Do not cover the unit! · Do not open the unit.
