User manual ZAPCO STUDIO 100

[. . . ] The amplifier is protected for any conceivable problem, including over-voltage, speaker shorts, overheating and reverse polarity. 2 Studio 100 Key Features · · · · · · · · · · · 100% symmetrical circuitry for low THD, TIM and IMD. Gold plated power, RCA and speaker connectors. Separate LED's for power and protection. Short circuit, high temperature, reverse voltage, DC offset and over-voltage protection. [. . . ] Connect the "NEG" terminal to the vehicle chassis with the shortest possible 10 gauge wire. Do not make this connection directly to the battery. Do not use seat or seat belt bolts for grounding. Do not share this connection with other equipment. A "single point" ground for high current connections will degrade the system's performance. Inadequate power supply connections will result in REDUCED POWER OUTPUT. Connect the "TURN ON" terminal to the radio's "amp turn on" or in some cases "power antenna" lead. This connection requires very little current and may be connected with a light gauge wire such as #22. Applying 12 volts to this terminal turns the amplifier on. 5 Signal Wiring Guidelines Control Endplate Input Connection: Connect the right and left input signals to the corresponding RCA input jacks on the end of the Studio 100. Keep these wires close to each other and far away from power and speaker wires. When using in bridged mono mode, put the input mode switch in the "MONO" position. Input Sensitivity: The input sensitivity or "gain" is user adjustable and can be set anywhere between . 230 volts (230 millivolts) and 2. 3 volts. If you are unsure of your head unit's maximum undistorted output level, set these controls to their minimum (quietest) position and then turn the head unit's volume knob up until you can start to hear audible distortion and reduce the volume until the distortion goes away. At this volume setting, gradually increase the amplifier's sensitivity until you can start to hear distortion from the amplifier. Then reduce the sensitivity until it goes away. Using this method, the head unit's volume should reach approximately 3/4 of its maximum or more before distortion is heard in the system. Speaker Connections: Connect the speaker wiring to the terminals as labeled. The minimum impedance or "ohm load" individual channel is two ohms. When bridging the rear channel into a mono configuration, the impedance is four ohms. they are for each front and minimum 6 Warnings ZAPCO highly recommends that a system protection device (i. e. , fuse or circuit breaker) be placed within 18" of the battery. Although ZAPCO products have adequate internal protection, it is possible that power wiring could become pinched between the component and the battery - potentially resulting in a fire. The system protection device should be placed where it can be accessed easily and all wiring should be routed safely and correctly according to the following guidelines: · · Do not run wiring close to hot or spinning objects.
