Xtant 302A - Manual (Page 6)

The 302a is a 300 Watt, stereo amplifier designed to provide
high power, exceptional flexibility and outstanding perfor-
mance in an all-in-one package. The 302a can drive a complex
speaker system or, be used to create a high-powered, bi-ampli-
fied, three-channel system when paired with Xtant’s 301a mono amplifier.
The on-board “Balanced Line Inputs” will accept a wide range of input sig-
nals – from your OEM Factory head-unit to the latest advances in CD head-
unit technology. The “Balanced Line” circuitry also helps eliminate noise
(alternator whine) induced into the signal cables.
As with all Xtant amplifiers, the 302a incorporates a forced convection ther-
mal management system, a Pulse Width Modulated power supply for unsur-
passed reliability and three on-board accessory ports allow performance
upgrades via Xtant’s plug-in modules. All these features are encased in
Xtant’s exclusive finish of polished stainless steel and copper!
Standard Features
Forced Convection Cooling: The 302a employs forced convection
cooling for thermal management. An on-board thermal sensing
circuit regulates fan speed to maintain optimum operating
temperature.
Balanced / Floating Input: The 302a is supplied
with Balanced / Floating inputs. When engaged, this cir-
cuitry 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 302a
Modular Expansion Ports: The 302a is supplied with three modu-
lar port(s). Two of the ports are dedicated to the amplifier and allow you to
dock any of Xtant’s signal processing modules. The third port is reserved for
add signal processing to the RCA line outputs. The modular method of sys-
tem expansion is a convenient means of adding the level(s) of signal process-
ing 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 termi-
nals” may be used with any speakers that you desire to attenuate (ie tweet-
ers / 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 302a. In the event of a problem, either thermal or over-
current 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.
