 Pojačalo 100V Crown 135MA :

Malo pojačalo idealno za manje prostore kafiće i kancelarije.

Ima 3 ulaza npr. Kompjuter, Tv, Kablovska.. I regulaciju zvuka potenciometrom kao na mikseti. Glavni potenciometar je jačinu zvuka a ton kontrola Bass Treble je ispod glavnog potenciometra.

Specifications :

Line: > 60 dB. Telephone: > 60 dB. Inputs 2 or 3 (and 4 in 160MA): > 78 dB. THD + N: < 0.5% at rated power at 1 kHz. < 0.1% at 5W at 1 kHz. Input Sensitivity (for full output at maximum gain): Input 1: Mic 3mV, Line 800mV. Input 2: 400mV. Input 3: 400mV. Input Impedance (nominal): Mic: 2.2 kilohms. Line: 10 kilohms. RCA: 10 kilohms. Crosstalk: –82 dB at 1kHz (Ch. 1 line input 0.8V, Ch. 1 volume at minimum, other channel volumes at maximum). Line Output Level (nominal): 1V into 10 kilohms. Phantom Power: 15 VDC. AC Line Voltages Available: Universal Power Supply. Line voltage tolerance +15%, –20%. Operating Temperature/Humidity: 0° C to 40° C at 95% relative humidity (non-condensing). Storage Temperature: –20° C to 85° C. Front Panel Controls and Indicators Power Switch: Pushbutton on-off switch. Input Volume Controls: Four controls, one per input. Detented potentiometers with knobs. Tone Controls: Bass and Treble non-detented recessed potentiometers under master output volume control. Bass ±10 dB at 100 Hz, Treble ±10 dB at 10 kHz. Power Indicator: Blue LED indicates power on. Input Signal Presence Indicators: Green LED, one above each channel's input attenuator, illuminates when input signal exceeds –40 dBu. Input Signal Clip Indicators: Green LED, one above each channel's input attenuator, fl ashes brightly at threshold of audible distortion. Output Signal Presence Indicator: Green LED above master output volume control illuminates when any input signal exceeds –40 dBu. Output Signal Clip Indicators: Red LED above master output volume control fl ashes brightly at threshold of audible distortion. Master Output Volume Control: Detented potentiometer with knob. Back Panel Controls, Connectors and Indicators AC Power Inlet: Detachable IEC accepts US or Euro style power cords. Amplifi er Output Connector: 4-position terminal barrier block with COM (Common), 8 ohms, 70V and 100V terminals. Accepts up to 10 AWG terminal forks. Non-touch cover included. Preamp Line Out Connector: 3-pin balanced Phoenix-type for connection to external amplifi - ers. Level independent of master volume control. Input Connector 1: 5-terminal Phoenix connector. 3 terminals for balanced signal, 2 terminals for priority contact closure, which mutes other channels when DIP switch 3 is on. Input Connector 2: Unbalanced line-level RCAtype connectors. Input Connector 3: Unbalanced line-level RCAtype connectors. Telephone (MOH) Output Connector: 4-terminal Phoenix connector (2 terminals for 1W output to 8-ohm speaker, 2 terminals for 600-ohm output to PBX music-on-hold port). MOH Level Control: Trim pot adjusts level for Music-On-Hold output from Telephone (MOH) Output Connector. Amp Confi guration DIP Switch: DIP switch selection for multiple functions. 1. On: Sets CH1 to Mic Input. Off: Sets CH1 to Line Input. 2. On: Sets CH1 to Normal mode (no priority). 3. On: CH1 priority contact closure mutes other channels. 4. On: CH1 VOX mutes other channels by sensing signal through Input 1. 5. On: Routes CH1 to MOH output. 6. On: Routes CH2 to MOH output. 7. On: Routes CH3 to MOH output. 8. On: 15V phantom power. VOX Threshold: Trim pot controls how loud the voice on CH1 must be before muting other channels. Can be set for no muting. Cooling Convection cooled. Protection Included protection mechanisms are current limiting, over-temperature thermal cutout, and DC-fault load protection. The unit is protected against turn-on/turn-off thumps.
