MOSFET POWER AMPLIFIERS Installation Instructions / Owner's Manual HA400 HA600 HA1000 HA740 HA700M HA1000M HA1040
INTRODUCTION Congratulations on your purchase of a Baja state-of-the-art power amplifier. Your selection of a Baja car audio product indicates a true appreciation of fine musical reproduction. Whether adding to an existing system or including your Baja amplifier in a new system, you are certain to notice immediate performance benefits. KEEP YOUR SALES RECEIPT Take this time to attach your sales receipt to the manual and put in a safe place.
SAFETY PRECAUTIONS Fuse amplifier's power wire at the battery. Be sure to fuse the power wire within 12" of the car's battery. This will protect the car's battery in case of a short circuit between the power amplifier and battery. THIS IS A MUST. The amplifier's built-in fuse will only protect the power amplifier and not the car's battery! The fuse value is based on the amplifiers rated power and how many amplifiers will be run off the same power wire.
FEATURES AND BENEFITS Built-in Crossover The Baja amplifiers include a built-in variable **high and low pass crossovers. The crossover features a variable frequency selection of (80 Hz ~ 1.2k Hz) for precise high pass filter and (50 Hz ~ 250 Hz) for low pass filter. ** HA1000, HA700M and HA1000M models only have a 50 Hz ~ 250 Hz low pass filter. Bass Boost For added low frequency performance the amplifiers are equipped with a variable 0~12 dB bass boost @ 45Hz.
Tri-Mode Capable (Excluding HA700M & HA1000M models) If so desired the amplifier may be run in stereo and mono at the same time. For example, this feature would allow you to run a pair of mids and tweeters in stereo and a subwoofer in mono. Remote Turn-on Automatically turns amplifier on when connected to the head unit's remote output. The amplifier will turn on and off with the head unit to save current consumption. This control also operates the reset circuit for the amplifier's protection.
Short Circuit Protection The circuit protects the amplifier from damage due to a short found in the speakers or wiring. If one of the speakers or its wiring comes in contact with ground, the amplifier will shut down. To resume normal operation, correct the problem and turn the head unit off, then back on. The amplifier will reset and play again.
POWER CONNECTIONS IN-LINE POWER FUSE MOUNTED WITHIN 12" FROM BATTERY RECOMMENDED (NOT PROVIDED) RADIO'S REMOTE TURN-ON OUTPUT CAR BATTERY +12V IMPORTANT! Before making any connections, disconnect the car's battery until the installation is completed to avoid possible damage to the electrical system. Connect the B+ terminal of the amplifier to the car's battery. At times, the amplifier will need to draw large levels of current that cannot be provided by any circuit in the car's fuse box.
MOUNTING LOCATION Before you start the installation, it will be necessary to find a mounting location for the amplifier. Find a location in which the amplifier will receive adequate ventilation in order to dissipate the heat it develops during operation. Two popular mounting locations are in the trunk or under the seat. Select the location in which you wish to mount the amplifier. Use caution when mounting the amplifier.
SIGNAL CONNECTIONS Connect the RCA output of the head unit (AM/FM cassette player, CD, or DAT) to the RCA input terminals of the amplifier. To make these connections, we recommend high quality RCA cables, which are available at your local car audio retailer. Run signal wires away from electrical wires to avoid possibility of induced noise from the car's electrical system (i.e. popping noises or engine noise).
HIGH LEVEL CONNECTIONS (OPTIONAL) High level inputs have been included in all Baja amplifiers excluding 4 Channel amps to connect the amplifier to a factory radio without low-level RCA outputs. This connection will allow you to connect directly to the speaker output of the radio, without the need of an external adapter.
SPEAKER CONNECTIONS Make the speaker connections using speaker wire that is at least 14 gauge or heavier. As with any audio component, proper phasing of the amplifier and speakers is essential for strong bass response. When connecting, make sure that positive (+) from the amplifier is connected to the positive (+) of the speaker, and the same for negative (-).
SPEAKER CONNECTIONS (BRIDGED) Two and four channel amplifiers are capable of being bridged ** into a mono configuration. This feature allows you the flexibility of using the amplifier to drive a subwoofer or a center channel. In this configuration the amplifier sums the right and left channel to deliver one channel (mono) output. Please note: In order for the amplifier to sum left and right signal information, both left and right RCA connections must be made.
SPEAKER CONNECTIONS (TRI-MODE) All 2 channel amplifiers are capable of running both in Mono & Stereo mode. This feature gives the amplifier the ability to run stereo satellites (midbass & tweeter) simultaneously with a mono subwoofer. These connections are more complicated because they require the use of passive crossover networks (Not provided) to divide the frequencies to the speakers. We have included a sample diagram for 4 Ohm connections.
SETTING THE CROSSOVER AND BASS/TREBLE BOOST (Please note: If you intend to use the amplifier in the Tri-mode configuration, it is necessary to set the crossover control to the "Full" setting in order to receive full range output) The Baja amplifiers are equipped with a built-in variable crossover network allowing you to select the crossover type, " Low-Pass" or "High-Pass". Low Pass Setting with Bass Boost.
USING SUBSONIC FILTER AND PHASE CONTROL Using the Subsonic Filter. Subsonic 30 20 50 Models HA1000,HA700M, and HA1000M are equipped with a variable 20~50Hz subsonic filter. This filter avoids the reproduction of inaudible low frequencies on the amplifier which could damage the subwoofers because they can generate overdisplacement of the subwoofer cone. You would want to set the frequency point where you want the filter not to produce frequencies below that point.
TROUBLE SHOOTING THE SYSTEM We have put together this trouble-shooting guide if you experience problems after installing the amplifier. Please keep in mind that the majority of problems incurred are caused by improper installation and not the equipment itself. In addition, there are many components in the system that could cause various signal problems such as inducted electrical noise and engine noise.
