• Five parametric EQ and howling prevention technique of digital frequency-shift two
• Microphone gain is increased to 5~14dB
• Before the meeting having to do debugging, power up immediately into meetings
• Each mic 48V independent switches
• Each microphone independently frequency switch
(A) technical data:
• Power supply: AC220V-230V,50/60Hz
• Four-channel microphone phantom power input
• Four-channel microphone phantom power independent switch selection
• Four-channel microphone-frequency-independent switch to select
• The receiver adjusted independently
• External 3-channel audio line-in volume adjusted independently
• Pitch control
• External 4-16 ohm speakers
• Frequency: 5 Hz ± 1 Hz
• Output power: 100W+100W
• Line input impedance 5K ohms
• Line output impedance ≤ 600 ω
• Frequency response: non-frequency-shifting 20 Hz-20K Hz
Frequency-shift 150 Hz-15K Hz
Basic operation:
1, put the amplifier's power switch (1) off, plug the power supply (27), connect the speaker (25-26), plug in a microphone (21-24), down to a minimum, select on or off microphone phantom power 48V switching. Turn on the power (1). On or off as needed that correspond to the various microphone frequency shift switch (12). To balance the volume of various microphones (3-6), and then head down to the appropriate location, adjust the volume of the demand for environmental sound field to achieve the best.
2, connected to an external signal source (18, 19, 20), the adjuster (14, 15, 16) volume, depending on the demand for sound to reach the scene.
3, the use of microphone phantom power 48V power must be switched off.
