Excursion HXA-45

4-channel car amplifier with a power of 4x70-90W / 2x180W, stable up to 2Ω, analog (class AB), Hi/Lo signal inputs, Auto Turn On/Off, small dimensions.

Analog 4-channel amplifier with high efficiency and small dimensions built on the basis of a double-sided PCB made in SMD surface mounting technology. The amplifier is equipped with a noise and interference elimination system, as well as a multi-way protection system against overload, short circuit at the speaker output, overheating and too low or too high supply voltage. The standard equipment also includes smoothly adjustable LP and HP filters with the ability to work in the BP Subsonic mode (Band Pass), a bass enhancement equalizer "Bass Boost", an "Auto Turn ON/OFF" system that controls switching the amplifier on and off, and "High/ Low Input” for the audio signal at speaker level and RCA level (common signal inputs for "High/Low" mode via RCA sockets). The HXA-45 amplifier can work stably with a load with a minimum impedance of 2Ω in each channel or 4Ω with a BRIDGE connection system (bridge).

• Front/Rear audio signal input: 4xRCA (common for HIGH/LOW signal).
• Audio signal output: none.
• Switches to select the HIGH/LOW input signal level (speaker level signal or RCA).
• Common HIGH or LOW signal input via RCA sockets after selecting the appropriate mode of operation with the LEVEL switch (we recommend using RCA/GŁ Excursion XML and Excursion XFM adaptive connectors - sold separately).
• Choose from 3 options for controlling the switching on and off of the amplifier (on/off switch option selection):

  1. REM - control by supplying +12V control voltage from the

  2 radio to the "Remote" connector. DC - automatic DC control (approx. +6V) downloaded by RCA inputs from the speaker cables of the radio player (works after selecting the LEVEL switch of the signal input with the speaker level - HIGH)

  3. AUDIO - automatic control of the amplifier when audio signal pulses are detected on RCA inputs (e.g. music). This option has a time delay system.

• Corrosion resistant nickel plated wire sockets and connectors.
• Terminals for spade connectors for power cables.
• Fork connector terminals for speaker cables.
• Protection systems against overload, short circuit at the speaker output, overheating and low voltage.

TURN ON/OFF - 3 amplifier control options (Remote)

The Excursion HXA-45 amplifier has a “Remote” system responsible for switching on and off the amplifier, which can operate in three modes selected by the ON/OFF switch. The first variant (REM) works for the HIGH and LOW input signals and this is the standard amplifier control by supplying +12V voltage to its REM connector. The other two control variants (DC and AUDIO option) work as an "Auto Turn On/Off" chip and can be used in the event that the radio player does not have a standard "Remote" control output. If the ON/OFF switch is in the DC position and the type of HIGH signal input (speaker level signal) has been selected before, the system will automatically turn on the amplifier when, after turning on the radio player, a constant voltage of approx. appears on its speaker wires. 6V in relation to the power mass. This type of control can be used for most standard radio players with an internal power amplifier built on the basis of integrated circuits. However, this option may not work with more advanced factory audio systems that have been equipped with an external amplifier, where there is no constant voltage on the speaker wires (e.g. some BMW models). If the ON/OFF switch is in the AUDIO position, the system will switch the amplifier on or off depending on the detection of the presence of audio signal pulses on the RCA signal inputs. This mode has a time delay system. When using the "Auto Turn On/Off" system (DC or AUDIO option), the REM +12V connector located at the connectors of the power cables acts as an automatically controlled REMOTE output, which can be used to switch on/off other devices, e.g. more power amplifiers.
