Resumen del manual
6. Variable Hi, 12dB / Low, 24dB Mono @40Hz–350Hz X-over – This control allows the user to choose the exact low pass or high pass frequency range the amplifier will play for the best possible performance. A high pass or full range output may be selected for the front output. A high pass, low pass, or full range output may be selected for the rear output. The upper end of the low pass crossover range can be selected from 40Hz–350Hz at 24dB per octave with a mono output. The lower end of the high pass crossover range can be selected from 40Hz-350Hz at 12dB per octave with a stereo output. 7. ThunderEQ (Variable) – This feature will add up to 18dB of low frequency impact to the audio system. The Bass Boost is centered at 40Hz. 8. A.R.C. – The Active Resonance Control (A.R.C.) is a level adjustment that reduces the resonant frequencies inside the vehicle to improve the midrange sound quality. Turn this in either direction until the vocals of the music are up front and centered in the vehicle. The midrange sound should be smooth and detailed. 9. Remote Subwoofer Level Control (Remote Gain) – This port allows the use of the optional “remote level control”. The Remote Subwoofer Level Control is a bass control module that can be installed in any location within the vehicle for remote adjustments. 10. Dual Mono Output (low pass only) – This feature is used when driving subwoofers and the amp is wired in a bridged front and bridged rear configuration (2-channel) or all channels combined configuration (1-channel) to ensure all channels receive the same signal. 11. Summed Front/Rear Line Level Output – This line level output is used to send a signal to an additional amplifier. The signal is not affected by front/rear fading. 12. StreetWires Connectors – All MTX amplifiers include StreetWires connectors for efficient current and maximum voltage transfer. 13. Speaker Connection – These output terminals are individually labeled for proper speaker connections. When bridging the amplifier, use the left positive terminal and the right negative terminal only. Warning, do not bridge the amplifier with an impedance lower than 4 ohms. 14. Power Terminals – This is the main power connection for the amplifier. The power and ground wire size should be the same gauge. • GND – The ground wire from this connection must be attached to bare metal on the vehicle. The distance to the ground should be as short as possible and no more than 18”. • REM – To turn the amplifier on/off, this terminal must be connected to the source unit’s “remote or electric antenna” wire. • +12V – The power wire from this connection must be attached to the positive side of the vehicle’s battery. • CAP+ - Capacitor Positive Input - The ideal connection point for the positive side of the capacitor to increase the amplifier’s performance. • CAP- - Capacitor Negative Input - The ideal connection point for the negative side of the capacitor to increase the amplifier’s performance. Before Starting MTX recommends that you have your new Thunder amplifiers installed by an authorized MTX retailer, preferably MECP certified. If you do decide to do it yourself, make sure you have read the instructions carefully and have the following tools: • Electric drill • Phillips bit or screwdriver • 1/8” bit • Wire cutters/crimpers • Safety glasses • X-Acto knife Disconnect the vehicle’s negative battery connection. Any deviation from the recommended connection procedures may cause serious damage to the amplifier, speakers, and/or vehicle electrical system. Please double check the connections before turning the system onprocedures may cause serious damage to the amplifier, speakers, and/or vehicle electrical system. Please double check the connections before turning the system on. Installation Mounting Place your Thunder amplifier at the predetermined mounting location. Use a felt pen to mark the exact position of the mounting holes on the mounting surface. Set the amplifier aside. Then with a sharp, precise blade cut small circles in the carpet and padding around the four marks denoting your mounting holes to expose the metal underneath. Use a center punch to make an indentation in the metal to ensure that you drill the exact position for the screws. Note: Please use common sense and make sure that all vehicle wires, gas lines, brake lines, etc. are clear and will not interfere with the installation. ALWAYS WEAR PROPER SAFETY GLASSES. Connections 1. Bi-Level Inputs (Low/High Level Input) with Smart Engage™ – Both a low and high level signal can be used. Be sure to lay the signal wire away from all power cables and vehicle computers. Use high quality twisted pair interconnect cables to decrease the possibility of radiated noise entering the system. • Using RCA Connections: If the source unit has RCA outputs, simply attach a signal cable from the source unit to the amp’s RCA input. This will provide signal to the amp. • Using Speaker Level Connections: If the source unit does not have...
