Features Thank you for purchasing an Axium AX-400DA Multi-Zone Amplifier. Please read this manual thoroughly before making connections and plugging in the unit. Following the instructions in this manual will enable you to obtain optimum performance and listening enjoyment from your new Multi-Zone Amplifier. Please retain this manual for future reference. Multi-Zone, Multi-Source, Video Switching The 400DA amplifier has four separate amplifiers providing 4 zones of independent yet integrated control.
Presets and Paging Amplifier ON Status – “Amp-On” There are 14 amplifier presets and two page presets. Presets 1 - 14 are momentary and cause the amplifier to go to a predetermined setup, i.e. standby, volume & source selection. The presets may also be programmed with event scheduling, and are used by the alarm clock. The ‘Page Preset’ mode is for paging applications and is invoked by a contact closure between the 0V and PG1 or PG2 terminals. The contact closure must have an external power source i.e.

Typical System Configuration – Continued FIG 1 depicts a typical configuration where the 400DA amplifier is providing audio into three of the possible four listening zones. Each zone consists of a room with a pair of speakers and a suitable controller. Each zone may be listening to any of the connected sources: Satellite, DVD, Tuner, Internet Radio, Media server, CD etc. Controllers Source Equipment Each zone has a specific control requirement. Choose controllers that best suit the application.
Multiple Amplifier Stacks To Next AX-400DA or AX-800DAV Multi-Zone Amplifier CD PLAYER SATELLITE RECEIVER TUNER DVD PLAYER FIG 2 In large installations where multiple 400DA or 800DAV amplifiers are required, the expansion bus may be used to convey inter-amplifier control, and common IR control. The source equipment audio must be plugged into the first amplifier where they are buffered and sent to the next amplifier in the stack. The maximum recommended expansion is eight units.
Controller Termination The 400DA is packed with control options: • • • • • • • • USB: Intended for initial installation Programming or firmware update. Not intended for permanent connection to a PC or other control system. ETHERNET: 100BaseT connection to a Home network router or switch. RS232 Serial: Electrically isolated Prevents hum in analog input circuits. CONTROLLERS: Conveys +12VDC, IR and Data between the 400DA and Axium keypad controllers, connected using CAT5 cables.
WEB Application The Axium 400DA amplifier has a WEB application which may be used for control and monitoring of amplifier and source functions. Home Page The home page provides access to the Amplifier zones. Selecting a Zone opens its control page.
Zone Control Page The Zone Control Page provides status & control of: • Standby • Volume: Slider or Up/Down button with readout. • Source Selection: S1 – S6 • Mute If the button is blue it indicates selection or ON status. Because of Web browser limitations, Slider setting changes are made using a positional touch on the slider The ‘Zones’ button is the Home Page return. Selecting the ‘Settings’ button will open the Settings page.
Zone Settings Page The Zone Settings Page provides status & control of: • Bass: Slider or Up/Down button • Treble: Slider or Up/Down button • Loudness • Balance: Slider or Left / Right button • Maximum Volume Limit: Slider or Up/Down button There is information displayed about the connected amplifiers Model and Unit ID and current Firmware version. The amplifier heatsink temperature is also displayed. The Back arrow button returns to the Zone Control Page.
Axium Music Centre Program AMC is an amplifier setup program, full control and tracking of the Axium amplifier zone is provided. The program runs on PC’s running Win XP, Win 7 or VISTA operating systems, and communicates via RS232, USB or Ethernet. AMC’s main window provides user functionality for real-time access and control of any amplifier zone. When an Axium amplifier is first attached to a PC running AMC the amplifiers clock is automatically set to the PC’s current time, date and location.
The Setup button opens the Setup window. Provides adjustments for Zone Equalisation, Balance, Delay, and Zone linking assignment. The Analog source input levels can be adjusted. If the source is a DVD player, the level should be set to 0dB. A Source will pulse red if input clipping is detected. Nominally the input should be set to 6dB. The Preset Setup on the AMC main page opens the Preset window. Preset programming can be entered for the Presets.
RS232 Protocol The RS232 serial port provides data acquisition and control of the Axium amplifiers by a home automation system, or PC. The interconnecting cable must be ‘Null modem’: 9 pin female ‘D’ connectors at both ends (pin connections 2 and 3 swapped at one end) only RX, TX & 0V (pin 5) are used. Baud Rate = 9600, Characters are all ASCII. Command Structure: line feed.
