SOUND Sound That WiII Move You THANKYOU Thank you for choosing Earthquake Sound 's line of mini D amplifiers, the best way to enhance your factory mobile audio system. With proper installation and responsible listening, your amplifier(s) will give you years of near perfect sound reproduction. We strongly recommend you to have your new amplifier(s) installed by an authorized Earthquake Sound dealer. Installation professionals employed by your dealer have the correct tools and knowledge to install your amplifier(s) neatly and successfully. Also, when your new products are installed by an authorized dealer, your products will include a ONE (1) YEAR L1MITED WARRANTY. Ifyou choose to perform your own installation, your warranty will be subject to further limitations. Dealer policies on handling warranty requests may vary from one dealer to the next. Please read the warranty information (Iocated at the end of this booklet) entirety and use good judgement when making these vital decisions. in its TABLE OF CONTENT5 Our Thank You.

Designed with the patented Optical Control Circuitry, each mini D amplifier comes with a built in protection fuse which can handle 1 to 4-0hm loads (it is most efficient in 2-0hm installation). Furthermore, the amplifier will automatically resets once the protection circuit is triggered, unless the problem persists. Equipped with soft clipping circuitry, these amps will not produce any audible distortion when c1ipped by 10%. -:-'- . ol~ ~~l . . ., DIO" • _O .

The pre-amplifier stage includes the following features: Bass Boost - available on the D2000 and D2500 models only The bass boost allows you to select the center frequency that you want to boost as well as the quantity. For most application, the best setting is at % turn (2 o'clock position). Variable Subsonic Filter Subsonic filters are often used to protect speakers from harmful low frequencies and DC voltage. Often clipped low frequencies could have the same effect as that of DC input. The best setting for most system is at 30Hz Highpass. LPF (Low Pass Filter) Often mistaken as crossover, the LPF is used to filter out unwanted mid and high frequencies, leaving the woofer to response to low frequencies. For most subwoofer application, the best crossing point is about % turn (2 o'c1ockposition). Gain Control Gain control regulates the amplifier's sensitivity to match the signa I output voltage of the audio source/head unit. It is not a volume control. The mini D amplifiers have gain controls that are extremely sensitive and therefore, should be adjusted with caution. When set at MIN, it will need 4V to clip these amplifiers. But with a mere '/4 turn, the amplifiers can clip with only 0.5V. www.earthquakesound.com 3 mini D ImpUri!. FUNCTIONS AND FEATURES mini DIOOO 1 mini DtOOO mini Dt500 CD POWER LED: When lit up, the amplifier is functioning properly . (]) PROTECTION LED: When lit up upon powering on, the amplifier may be in self­ test mode . Ifthis LED stays on, shut down the amplifier and locate what may have triggered the amplifier to protection mode. If problem persists, cali us for further assistance. @ REMOTE SUB LEVEL: Used to adjust the amplifier's bass output fram a location ofyour choice. 8) RCA INPUT: Low level inputs with range of O.1V to 5V RMS. Be sure to use a HIGH LOW LEVEL adaptor ifthe hear unit has only speaker output. ® BRIDGE IN/OUT: Used when linking 2 amplifiers together. The BRIDGE 11\1 receives signal from the master amplifier and should only be used when the amplifier is the slave amplifier (ali functions of the slave amplifier will be adjusted by the master amplifier) . The BRIDGE OUT sends signal to the slave amplifier and should only be used when the amplifier is the master amplifier. Note that both bridged amplifiers must be of the same model with minimum impedance is 2-0hm . ® GAIN CONTROL: Set based on the head unit's output voltage. Note, this is not a volume control. Always start at the MIN and slowly increase the gain. Stop as soon as distortion is heard then lower the gain until the distortion disappear and only c1ear sound is produced . (]) LPF (LOW PASS FILTER): Used to filter out unwanted mid and high frequencies . ® SUBSONIC FILTER: Used to protect the speakers from harmful low frequencies and DC Voltage. The best setting for most system is at 30Hz (2 o'clock position). 4 Specifications are subject to change without notice mini D omPlirlER FUNCTIONS AND FEATURES mini DIODO mini DIODO mini DI500 ® FREQUENCYAOJUST: Used to adjust the boosted centerfrequency. The best setting for most system is at ~ turn (2 o'clock position). Available on the D2000 and D2500 models only. @ BASS BOOST: Used to add o-12dB to the chosen centerfrequency.Again, the best setting for most system is at ~ turn (2 o'clock position). Available on the D2000 and D2500 models only. @ SPEAKER CONNECTION: These terminals have been internally bridged/jumped . When connecting to both sets of terminals, there is a 2­ Ohm minimum impedance per terminaI. @ FUSE: Used as an added protection from damaging excessive current. Be sure to use the proper fuse in your installation. Please refer to page 12 of this manual for the proper fuse rating. Note that the 02000 and 02500 reguire extemal fuses. @ +12V BATTERY TERMINAL: Connect to battery positive (+) using a 4 gauge cable. @ REMOTE TERMINAL: Connect remote cable to the head unit's remote terminaI. If multiple amplifiers are installed in the same system, additional relays may be necessary. ® GROUNO TERMINAL: Connect to vehicle's chassis/ground using a short 4 gauge cable (2 feet maximum in length). NOTE: Be sure to follow the wiring preparations/guidelines as Iisted on the next page to ensure proper installation. www.earthquakesound .com 5 mini D nmpurlER WIRING PREPARATIONS 0' Test the alternator output. Factory alternators will produce 60 - 80 amperes at best. Wear and heatwill reduce the output by 40% . 0' Alternator ground (-) must be reinforced. Use a 4-gauge cable instead of the factory 8-gauge. 0' Alternator positive (+) to battery (+) must be reinforced . Use 4-gauge cables. 0' Check your battery condition as batteries degrades after a whole. 0' Battery (+) to amplifier (+) must be connected using a 4-gauge cable . 0' Ground amplifier to vehicle's chassis (bare metal) using 4-gauge cable, keep the cable short (2 feet max) . 0' Use 1 Farad capacitorto compensate for surges in demando 0' We recommend the use of one (1) auxiliary battery. ., 6 Specifications are subject to change without notice mini D ImpUriE.
