Amplifires:

AMPLIFIER VB-290 A coach amplifier that allows the user to SELECT, AMPLIFY, MIXING. EQUALIZE following sound sources (CD, DVD, VIDEO, RADIO-CASSETTE, MICROPHONES…). Independent control over the sound sources (driver and passenger). Intelligent control of the VCP, DVD. Control of the bass and treble, and level of the microphone. Multifunctional graphic display. Karaoke system. C.A.N. communication bus. Automatic control of the power output. Priority for driver's microphone. Equipment protected for reverse polarity and short circuit in loudspeakers output. Technical Specification: POWER SUPPLY Voltage 12V or 24V +/- 20% (negative ground). Max Power consumption: 10 A. Max power output: 4 x 40 W / 4 Ohms. Continuous Power Output: 4 x 25 W/ 4 Ohms / THD 10%. Output Impedance: (Approx. 4Ohms) Installation Format: DIN ISO RADIO, CD, AUX1 INPUT Normal Input: 100 mV (RMS). Input Impedance: 50 KOhms Bandwidth: 30 Hz - 20 Khz Signal/Noise Ratio: >40 dB. MICROPHONE INPUTS Two independent inputs: 1 for the guide microphone and 1 for the driver microphone (with priority). Normal Input: 2.5 mV (RMS). Input Impedance: 2 kOhms. Bandwidth: 300 Hz - 3500 Hz. Signal/Noise Ratio: >50 dB. DC FOR RADIO CASSETTE Input: 14V; 1A AUDIO VIDEO INPUT Normal Input: 600 mV (RMS). Input Impedance: 50 KOhms. Bandwidth: 160 Hz - 8 KHz Signal/Noise Ratio: >60 dB.       AMPLIFIER VB-3860 Used for SELECTING, AMPLIFICATION, MIXING EQUALIZE following sound sources (CD, DVD, VIDEO, RADIO-CASSETTE, MICROPHONES…). Radio Cassette. Video. Guide Microphone. Flex neck microphone (priority). Aux1 & Aux2. On/Off switch where sound for driver is independent from saloon for amplifier or Radio Cassette. Easy to use potentiometer controls with separate general volume, treble, bass and microphone volume. Possible to mix signals between guide microphone, radio and audio from video player. KARAOKE system. Equipment protected for reverse polarity and short circuit in loudspeakers output. Auxiliary 14 V output to powered Radio Cassette, max. current 4A because the amplifier is protected so is the Radio Cassette. Fixing system uses metal anti-theft bracket. All sound sources are independent, so that if Radio Cassette is removed, microphones and audio for video player still operate. Incorporates internal noise suppression system. Technical Specification: POWER SUPPLY Voltage 12V or 24V +/- 20% (negative ground). Max Power consumption: 5,5 A. Max power output: 2 x 25 W R.M.S. Continuous Power Output: 2 x 18 W (1% dist. a 1 kHz). Output Impedance: between 3 & 8 ohm(normally 4 ohm). Installation Format: ISO RADIO, AUX 1, AUX 2 INPUT Normal Input: 100 mV (RMS). Input Impedance: 2 x 10 k0hm. Bandwidth: 30 Hz - 18 kHz (-3 dB). Signal/Noise Ratio: >60 dB. MICROPHONE INPUTS Two independent inputs: 1 guide microphone and 1 flex neck microphone (priority). Normal Input: 2.5 mV (RMS). Input Impedance: 2 k0hm. Bandwidth: 300 Hz - 3500 Hz (-3 dB). Signal/Noise Ratio: >50 dB. AUDIO INPUT FROM VIDEO PLAYER Normal input: 600 mV (RMS). Impedance: 600 ý. Bandwidth: 160 Hz - 8 kHz (-3 dB). Signal/noise ratio: >60 dB DC-DC CONVERTER FOR RADIO/CASSETTE Input voltage: 24 V +/- 20% Output voltage: 14 V +/- 2%. Efficiency: 86%. Output current: 5.5 A.       AMPLIFIER VB-2020R+C Specially designed for buses and coaches EQUALIZE following sound sources (CD, DVD, VIDEO, RADIO-CASSETTE, MICROPHONES…). Radio Cassette. Video. Guide Microphone. Sound for driver is independent from saloon. The control are simple to use & the general volume is independent from the microphone volume. Protected against reverse polarity and short circuit of the speaker outputs. The microphone has priority over the radio/cassette output. A fully protected 14 V output is available to power a radio cassette (max. current 2.5 A). All sound sources are independent, so that if Radio Cassette is removed, microphones & audio for video player still operate. Technical Specification: POWER SUPPLY Voltage 24 V +/- 20% (Negative ground). Max Power consumption: 5 A. Max power output: 2 x 20 W R.M.S. Continuous Power Output: 2 x 18 W (1% dist. a 1 kHz). Output Impedance: between 2 & 8 ohm (normally 4 ohm). RADIO INPUT Normal Input: 100 mV (RMS). Input Impedance: 2 x 10 k0hm. Bandwidth: 30 Hz - 12 kHz (-3 dB). Signal/Noise Ratio: >50 dB. MICROPHONE INPUTS Two independent inputs: 1 guide microphone and 1 flex neck microphone with priority. Normal Input: 2.5 mV (RMS). Input Impedance: 2 k0hm. Bandwidth: 300 Hz - 3500 Hz (-3 dB). Signal/Noise Ratio: >40 dB. AUDIO INPUT FROM VIDEO PLAYER Normal input: 100 mV (RMS) - 1 V (RMS). Impedance: 10 kOhm. Bandwidth: 30 Hz - 12kHz (-3 dB). Signal/noise ratio: >50 dB DC-DC CONVERTER FOR RADIO/CASSETTE Input voltage: 24 V +/- 20% Output voltage: 14 V +/- 10%. Output current: 2.5 A.       AMPLIFIER VB-2020R Specially designed for buses (which do not have TV monitors). EQUALIZE following sound sources. Radio Cassette.
