BA400 BA440 MOSFET POWER AMPLIFIERS Installation Instructions / Owner's Man ual.
I NTRODUCTION 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.
S AFETY 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.
F EATURES AND BENEFITS DC Offset Protection This circuit protects the output of the amplifier against DC voltage. If for some reason DC voltage is detected at the output stage, the amplifier will shut down protecting the speakers from direct current.
Bass Boost For added low frequency performance the amplifiers are equipped with a variable 0~12 dB bass boost @ 45Hz. (BA 400 only) Power Fusing This protects the amplifier against short circuits and excessive current. Remote Turn-on Automatically turns amplifier on when connected to the head unit's remote output.
M OUNTING 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.
Connect 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. We recommended using an 10 to 12 gauge power wire for your connections depending on the amplifier and length of the wire.
7 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.
8 High Level inputs have been included to connect the amplifier to a radio without low-level outputs (i.e. factory radio). This connection will allow you to connect directly to the speaker output of the radio with out the need of an external adapter. Determine the type of radio you have and make one of the following connections.
FOUR CHANNEL CONNECTIONS: FLOATING GROUND RADIO (MOST COMMON TYPE) 9.
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 (-).
TWO CHANNEL BRIDGED SPEAKER CONNECTIONS FOUR CHANNEL BRIDGED SPEAKER CONNECTIONS S PEAKER CONNECTIONS (BRIDGED) The Baja amplifiers are capable of being bridged in a mono configuration. This feature allows you the flexibility of using the amplifier to drive a ** subwoofer or a center channel.
CAUTION! In Tri- mode operation, the amplifier must see a 2 Ohm load or higher for the stereo satellites and no lower than 4 Ohms for the subwoofer(s). Any lower than the above mentioned impedance will cause the amplifier to overheat and possibly cause permanent damage to the amplifier.
. (Please note: If you intend to us e the amplifier in the Tri-mode configuration, it is necessary to set the crossover control to the "Flat" 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 (i.
T ROUBLE 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.

Un punto importante, dopo l’acquisto del dispositivo (o anche prima di acquisto) è quello di leggere il manuale. Dobbiamo farlo per diversi motivi semplici:
Se non hai ancora comprato il Profile BA400 è un buon momento per familiarizzare con i dati di base del prodotto. Prime consultare le pagine iniziali del manuale d’uso, che si trova al di sopra. Dovresti trovare lì i dati tecnici più importanti del Profile BA400 - in questo modo è possibile verificare se l’apparecchio soddisfa le tue esigenze. Esplorando le pagine segenti del manuali d’uso Profile BA400 imparerai tutte le caratteristiche del prodotto e le informazioni sul suo funzionamento. Le informazioni sul Profile BA400 ti aiuteranno sicuramente a prendere una decisione relativa all’acquisto.
In una situazione in cui hai già il Profile BA400, ma non hai ancora letto il manuale d’uso, dovresti farlo per le ragioni sopra descritte. Saprai quindi se hai correttamente usato le funzioni disponibili, e se hai commesso errori che possono ridurre la durata di vita del Profile BA400.
Tuttavia, uno dei ruoli più importanti per l’utente svolti dal manuale d’uso è quello di aiutare a risolvere i problemi con il Profile BA400. Quasi sempre, ci troverai Troubleshooting, cioè i guasti più frequenti e malfunzionamenti del dispositivo Profile BA400 insieme con le istruzioni su come risolverli. Anche se non si riesci a risolvere il problema, il manuale d’uso ti mostrerà il percorso di ulteriori procedimenti – il contatto con il centro servizio clienti o il servizio più vicino.
