Integrated amplifiers Safety Instructions • P lease check the carton box for any kind of damage on reception of the goods. In case of a damaged carton, please contact your dealer before opening the carton. • ! !!! Danger !!!! Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably to noise induced hearing loss but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient amount of time.
CONCEPT1(T) Instruction manual • o not connect the inputs / outputs of amplifiers or consoles D to any other voltage source, such as a battery, mains source, or power supply, regardless of whether the amplifier or console is turned on or off. • P ower down & disconnect units from mains voltage before making connections. • o not use the unit near stoves, heat registers, radiators, or D other heat producing devices.

Microphone input: connect your (paging) microphone on this euroblock connector, connect the signal on +, -, the screen on GND. Connect the eventual paging contacts between GND and Z1 (for zone 1) and between GND and/or Z2 (for zone 2). The input gain can be adjusted with knob 2 between line and mic level to avoid distortion. 2. Mic input gain control: mic input gain adjust 3.
CONCEPT1(T) Instruction manual 9. Line D: stereo line RCA connector, a mini jack version of the line D input is available on the front panel. Only use one of the two input’s at the same time. 10. P re-amp out: these RCA connectors offer a line level signal, after the master volume, but before the limiter. For details, please take a look at the block diagram on page 7. 11. Line out: these RCA connectors carry the line level signal after passing the volume control and limiter circuit.

CONCEPT1(T) Instruction manual User Operation The table below shows the 3 possible operating modes: stereo, 2 separate mono zones with one linked music volume control and 2 separate mono zones with individual music volume control. You can adjust the volume by turning the large rotary control from -80 dB (lowest) to 0 dB (highest). Volume adjustment is the default parameter assigned to the rotary control. In order to enter the menu, press the select button next to the large rotary control.

CONCEPT1(T) Instruction manual Expert Operation In order to edit the EXPERT parameters, push select repeatedly until “EXPERT” appears in the display. Then press the ‘SELECT’ and the ‘SOURCE D’ button. A hidden menu structure is now available and gives you the opportunity to edit several parameters, such as operating mode, maximum music level and so on. The table shows the entire menu structure. The menu tree is also printed on top of the Concepct1 unit and should need no further explanation.
