UNDSTR SERIES ST1.700D ST4.
Thank you for your decision to purchase a MICRO MINI mobile amplifier! Our Amplifiers are the result of extensive engineering, testing, and bullet proof construction. Their versatility enables compatibility with optional signal and audio processors. These high quality MOSFET amplifiers may be configured to allow maximum flexibility in designing different types of speaker systems.
• Class-D Digital Full range 2ohm stable stereo. • Low-power Consumption Circuit. • Tri-mode capable. • Full MOSFET DC-DC PWM Power Supply. • Four way protection. • Double sided FR-4 PC Board. • SMD technology. • High level input connector (Auto turn ON). ·Adjusta ble Low-pass, Hi-pass, Bass boost, Sub sonic filter. • RCA input connectors (No Auto tum ON). • Connector to connector Power/Speaker terminals. • Ultra slim size.
~ INSTALLATION PRECAU TIONS NOTE: Proceed only ifyou are qualified installer otherwise, let your dealer do it. Always wear protective eyewear when using tools. • Tum off all stereo and other electrical devices before you begin. • Disconnect the negative (-) lead from your vehicles battery. • Locate all fuel lines, brake lines, oil lines, and electrical cables when planning the install. • Make sure there is at least 2-inches (5 em) around the air vents on the amplifier.
~ MOU NTIN G LOCATION Your MICRO MINI amplifier comes with mounting feet that need to be attached to the amplifie r prior to installation. Once the feet are in place, use the amplifier as a template and mark the four screw locations. Use caution to make sure there are no objects behind the installation surface that may become damaged during drilling. The amplifier should be protected from exposure to moisture and direct sunlight.

1. LINE IN (RCA) Jacks The RCA style input jacks are for use with source units that have RCA line level outputs. A source unit with a minimum of 250mV is required for proper operation. However, this input will accept levels up to 6Vrms. 2. High Level Input If you are installing by using a high level. you do not need to connect to the remote because. To hear a better sound quality, you must connect the high level ground wire to the head-unit ground. 3.
11. GND (Ground Input Connection) A good quality ground is required for your MICRO MINI amplifier to operate at peak performance. A short length of cable the same gauge as your power cable should be used to attache the ground terminal directly to the chassis of the vehicle. 12. REMOTE (Remote Input Connection) All MICRO MINI amplifiers can be turned on by applying 12 volts to this terminal. This can be found on the rear of the source unit in the form of an electric antenna output, or a remote output.
Disconnect the negative (-) battery terminal before you start any wiring work! The power supply of your car audio system must be disconnected until the entire wiring installation is completed. Your MICRO MINI amplifier requires unrestricted current to deliver peak performance, so don't "starve" your amplifier by using small power cable.

These amplifiers are designed to work within a 10 to 16.8 volt DC range. Before any wires are connected, the vehicles electrical system should be checked for correct voltage supply with the help of a voltmeter. First, check the voltage at the battery with the ignition in the OFF position. The voltmeter should read no less than 12V. If your vehicles electrical system is not up to these specifications, we recommend having it checked by an auto electrician before any further installation.
Remote This terminal must be connected to a switched + 12V source. Typically, remote tum-on leads are provided at the source unit that will tum on and off the amplifier in correspondence with the source. If the source unit does not have a remote tum-on lead, then a power antenna wire can be used. If neither of these leads is available at the source unit, then a switched+ 12V supply must be used, like the ACC, + 12V.

Power LED not ON With a Volt Ohm Meter (VOM) check: • +12 Volt power terminal (should read +12 to +16VDC). • Remote turn-on terminal (should read +12 to+16VDC). • Ground Terminal. Power LED is GREEN, no output • • • • Protection LED is ON, no output and • Thermal protection is engaged. Check for proper impedance at speaker terminals. Also check for adequate air flow around the amplifier. • Voltage protection engaged. Voltage to the amp is not within the 10-16.8 VDC operating range.
