The Zapco Studio X Series Amplifiers Zapco has a reputation for sound reproduction and quality that is unsurpassed. It is our dedication to sonic purity and our passion for performance that built that reputation. With all the new amps coming into the market, not one has been any threat to Zapco’s standing as the premium amp and processor line. Just check the audio competition scene and the audio forums. The pros know what to use to win. But not everyone wants to compete. The question was this.
Install Sense As a manufacturer, Zapco has taken great pains to produce a product that will give you many years of superior performance and reliability. However , certain basic rules need to be followed if you want to achieve the products potential in your vehicle. It takes power to make power. The power and ground wire is critical to your system. If the wire gauge is too small your amp will never produce its rated power. Even worse...

Rear Gain: This control balances output of the head unit to the input of the amp and with the front amp channels 4.
9. Front Gain: This control balances output of the head unit to the input of the amp and with the rear amp channels 10. Rear Outputs: These provide an RCA output to drive the front channels if the head unit has only one RCA out. Connect a short RCA between the Rear out and the Front In. 11. LPF: If you use the rear low pass crossover, this control determines frequency 20Hz to 1KHz 12.

The Studio X Mono Class D Amps There are three Class D mono amps in the Studio X line,. The ST-500X at 500 watts RMS, the ST-1000XM at 1,000 watts and the ST1500XM at 1,500 watts RMS. The ST-500XM Input Side 1 2 3 4 5 6 1. Remote each ST– X bass amp includes a wired dash remote for the bass output 2. RCA inputs accept the input signal from the head unit 3.
The ST-1000XM and ST-1500XM Input side The larger Studio X bass amps have all the features of the ST-500XM but they also add more bass control features See ST-500XM 1 2 1. The ST-1000XM and 1500XM offer a variable bass boost. This frequency control varies the boost frequency from 30Hz to 80Hz 2. The Boost control allows a bass boost of 0dB to 12dB.
1. GND The amp should have a firm connection the car frame. * See section "Install Sense" 2. REM The remote terminal connects to the head unit remote out, or to some other switched 12 volt source to turn on the amplifier. 3. +12V The main 12 volt must be connected directly to the vehicle’s battery using wire of the proper gauge. * See section "Install Sense" 4. Speaker connections The heavy duty terminal block provides positive speaker connections. Simple insert the wire and cinch down the set screw.
Strapping Studio X Mono Amps Studio X mono amps are true mono units and you can double their power by “strapping” two units of the same model together to drive a single voice coil. Always keep in mind that each amp must see a minimum load of 1Ω. A “strapped” pair of amps must see a minimum load of 2Ω (1 ohm per amp) Strapping the Inputs Bass Remote Head unit Output RCAs 1. Decide which amp will be the ‘master” amp and which will be the “slave” amp 2.

Connect the master amplifier’s speaker output (positive) terminal of the woofer. 2. Connect the slave amplifier’s speaker output + Terminal to the (negative) terminal of the woofer 3. Connect the Connect the two amplifier’s speaker output terminals together - - (negative) Note: You are creating a much more powerful amplifier in this way and doubling the output.
Speaker Connections ST-2X Standard stereo hook-up connects + and-leads from the correct terminal to each speaker, taking care that no wire or speaker terminal makes contact with the metal vehicle body. A bridged 3 channel “mixed mono” mode can be used to run Mids/Highs in stereo and a Sub in Mono from the same stereo outputs. To maintain proper impedance you must use passive crossovers (see below) when in mixed mono configuration.
ST-4X Like the ST-2X, the ST-4X will drive 4Ω or 2Ω loads and can be hooked in 3 channel mixed mono mode.
You can create a high power stereo amp by using the ST-4X in Dual Mono mode where the front amp powers one channel and the rear amp powers the other. 4Ω Min Load You will use Y-adapters to put the left input into both front channels and the right input into both rear channels 4Ω Min Load ST-5X The ST-5X puts everything together in one do-all amplifier.
