The 

XETEC xi-440.5

is a state-of-the-art 5-channel car audio amplifier,

especially developed for top quality speaker systems and subwoofers.
A perfect choice are the 

XETEC

Component systems and subwoofers.

You can also run each 2 of the 4 channels in bridged mode to gain more
than twice the output power, in order to drive subwoofers, midbasses or
high power component systems.

The versatility and many adjustment options make the 

XETEC xi-440.5

an

allround genius for car music reproduction.

PROPERTIES

• HPAA Amplifier (High Precision Analog Amplifier) 
•  BLC (Bass Level Controller)
•  Independent low- and highpass filters (bandpass possible)
• Protection circuit: Overload, Short-circuit, DC, Overheat

SAFETY

Before you make any connection, the battery must be
disconnected!

A main fuse must be installed into the +12 V wire within the
first 12" from the + terminal of the battery (insurance regulation!).

Please note that a minimum speaker impedance of 2 Ohms
(>4 Ohm in bridged mode!) must be maintained.
Do not connect speakers with lower impedance in normal as well as
in bridged mode!

Make sure that you do not use defective speakers and
subwoofers.They can cause damage to your amplifier!

The fuses inside the amplifier only protects the device itself, not the 
battery and the car!

IMPORTANT NOTICE: STABILITY OF AMPLIFIERS

Normal operation:

Every amplifier is only capable of driving loads (speakers) up to a certain
limit, which is set either by the protection circuits or the maximum power
output.

XETEC

amplifiers accept loads down to 2 Ohms in normal operation.

Bridged mode:

In bridged mode each two channels of the amplifier are driving the same
load, the acceptable impedance for each channel is also 

divided by two!!!

That means:

A normal amplifier „sees" 4 Ohms as 4 Ohms. In a bridged amplifier, each
amplifier „sees" 2 Ohms only!!! That’s why in bridged mode always 4 Ohms
must be maintained although the amplifier might be 2-Ohms stable.

CAUTION
This product is capable of conducting very high sound pressure
levels, and can thus be harmful to your health. Prolonged exposure
to high volume levels can cause hearing loss! Please use restraint on 
the volume control. XETEC wants you to enjoy your amplifier for a 
long time to come, and we do not take responsibility for hearing loss 
nor other health problems.
