User manual XTANT 403A

[. . . ] We all became excited about the possibilities. We Listen to your recommendations, opinions, and needs. We Listen to our fellow supporting manufacturers to ensure that our products interface well with a wide variety of products. We Listen to our equipment with sensitive and critical ears to provide the finest mobile audio components on the planet. [. . . ] When engaged, this circuitry helps to eliminate "system noise" associated with "ground-loops". It also increases input sensitivity which "widens the scope" of head units for use with the 403a Modular Expansion Ports: The 403a is supplied with five modular port(s). Four of the ports are dedicated to the amplifier and allow you to dock any of Xtant's signal processing modules. The fifth port is reserved for add on signal processing to the RCA line outputs. The modular method of system expansion is a convenient means of adding the level(s) of signal processing to satisfy your unique system requirements. resistor modules / passive speaker terminals: The Resistor Modules (RM) serve two purposes. First, they activate the "passive speaker terminals" and attenuate (turn down) the level of any speakers connected to these terminals. Designed to power the rear fill speakers, the "passive terminals" may be used with any speakers that you desire to attenuate (ie tweeters / center channel). The RM Modules offer four levels of attenuation: -4, -8, -12, or -16 dB. Protection Circuitry: Both Thermal and Overcurrent protection are incorporated into the 403a. In the event of a problem, either thermal or overcurrent protection will reduce amplifier power to maintain operation. Status LEDs: Three LEDs, visible through the cover, indicate operational status of all Xtant amplifiers. The red LED illuminates when the amplifier is "ON", the yellow LED indicates that overcurrent protection is employed and the orange LED glows when the thermal protection circuit is operational. 5 Xtant 403a SPECIFICATIONS Frequency Response Number of Channels Watts per Channel @ 4 Watts per Channel @ 2 Stereo Ch.

The four ports dedicated to the amplifier are labeled Amp Vert/Horiz Acc Port and Amp Vert Acc Port. The fifth port is dedicated to the RCA line outputs and is labeled Line Out Vert Acc. Xtant offers two types of accessory modules which are designed for either "Horizontal" or "Vertical" mounting. The docking port, located behind the RCA line outputs, labeled Amp Vert/Horiz Acc Port will accept any module, while the ports labeled "Vert" will only accept modules designed for vertical mounting. The following is a list of Xtant Accessory Modules including their "Horizontal" or "Vertical" mounting design: XTANT ACCESSORY MODULES Mounting Model Function Mounting HORIZ HORIZ VERT CM12H CM12L NGM-1 XOVER XOVER NOISE GATE VERT VERT HORIZ Model CM 24X PQM-1 LFQ 45 Function XOVER EQ BASS EQ The four accessory ports dedicated to the amplifier allow you to add the level(s) of signal processing that your system requires. An example would be if a band pass function is required, a CM12H (high pass at the lowest frequency of the band pass) and a CM12L (low pass at the highest frequency of the band pass) could be used to create a 12 dB per octave band pass filter. A more basic set-up would be a PQM-1 EQ module and a CM 12 crossover module. The Line Out Vert Acc Port will only accept one of the "vertical" accessory modules.
