XXV EDITION HIGH PERFORMANCE AMPLIFIERS
As Hifonics celebrates its 25th anniversary of producing the finest high end car audio products available we would like to thank
you for your continued support.
The GEN XXV Series range of products have been designed to a very high level of performance, with features unavailable in any
other product.
All of the amplifiers have variable crossovers built in, with added touches such as Subsonic Filter, Parametric Bass Equalization,
Phase Shift, Balanced Line Input and a Bass Remote Control Module that allows bass control from reach of the drivers seat.
To insure years of listening pleasure, all amplifiers have a built in diagnostic mode that will detect shorted speaker leads, low
impedance, dangerous high temperatures, DC shorts and will shut down the amp to help prevent serious damage. A new feature
for this series is the Clipping LED indicator. This indicator is located on the amplifier end panel and Bass Remote Control Module.
This LED alerts the user when the amp reaches soft clipping and allows the user to correct the settings prior to reaching hard
clipping and shutting the amp down. To ensure incredible durability, all XXV D-Class amplifiers are now 18 Volt stable, except for
the XXV-Colossus which is 16 Volt stable.

channel, or 4 Ohm mono bridged operation. The XXV Colossus and XXV Crossover filter slopes are 12 dB/octave for stereo filters, and 24
Maxximus are capable of 4, 2 & 1 Ohms stereo per channel, or 4 & 2 Ohms dB/octave for mono filters.
mono bridged operation. The XXV Thor, XXV Cyclops, XXV Goliath, and
XXV Sampson are capable of 4, 2 & 1 Ohms.
Tri-Mode operation with any stereo pair of amplifier channels is possible,
as with all bridgeable amplifiers.
The input sensitivities for rated output powers are variable from 0.2 volt to
9 volts.
A POWER LED indicates the powered up and turned on condition.
All HiFonics amplifiers feature a comprehensive diagnostic system, with
speaker lead short circuit, thermal over load and amplifier DC faults
indicated by the PROTECT LED’s. The XXV series also features a new
clipping led indicator that changes colors as the severity of the clipped
signal increases.
CLASS A/B FRONT MOUNT CONTROL FEATURE DESCRIPTIONS
SUBSONIC: The variable Subsonic filter is fully adjustable from 15Hz to 150Hz.
PARAMETRIC BASS EQ:
CUT /
BANDWIDTH: The bandwidth is fully adjustable from narrow to wide.
FREQUENCY: The frequency is fully adjustable from 40Hz to 400Hz with a selectable X1 or X10 multiplier.
CROSSOVER: The 2 channel amps have 2 crossover switches. One allows you to select HPF (high pass filter), LP/BP (low pass-band pass filter)
at 12dB or 24dB mono. The second switch allows you to select mono or stereo operation while in LP/BP configuration. The 4 channel amps have
separate CROSSOVER controls for channels 1 / 2 and channels 3/4.
INPUT MODE: In the Ch2 position, all 4 amplifier channels derive their input signals from Ch1 & Ch2 Line Inputs (RCA). When set to Ch4,
channels 1, 2, 3 and 4 receive input signals from Ch1, Ch2, Ch3 and Ch4 Line Inputs (RCA).
BOOST: The bass cut / boost is fully adjustable from -10dB to 10db.
D-CLASS SIDE MOUNT CONTROL FEATURE DESCRIPTIONS
SUBSONIC: The variable Subsonic filter is fully adjustable from 15Hz to 35Hz.
LOW PASS FILTER: The low pass filter is fully adjustable from 35Hz to 250Hz.
PARAMETRIC BASS EQ:
BOOST: The bass boost is fully adjustable from 0dB to 10db.
BANDWIDTH: The bandwidth is fully adjustable from narrow to wide.
FREQUENCY: The frequency is fully adjustable from 30Hz to 100Hz.
MASTER / SLAVE: The mono amps (XXVThor / XXVCyclops / XXVGoliath, XXVSampson) allow you to electronically “link” two amps together
so that you can power and single subwoofer with two amplifiers.
SHARED CONTROL FEATURE DESCRIPTIONS
BALANCED INPUT: Accepts balanced line inputs from 0.2 volts to 18 volts for the optional MMBLD-1 balanced line driver.
LINE INPUT: Accepts unbalanced RCA inputs from 0.2 volts to 9 volts.
LINE OUTPUT: The unbalanced RCA outputs are set the same as the CROSSOVER switch on the front mount control and end panel.
LEVEL: The input level control allows you to match the amplifier input sensitivity to the output level of the RADIO/CD source from 0.2 Volts to 9
volts when using unbalanced (RCA) and 0.2 volts to 18 volts with the balanced input.
PHASE SHIFT: The Phase Shift is fully adjustable from 0 to 180 degrees.
SYSTEM DIAGNOSTICS: The amplifier has built-in monitoring devices and protection circuits that monitor all vital functions of the amplifier.
The diagnostics light do not come on to indicate there is a failure, they come on when they detect an improper operation.
THERMAL: The amp has an internal temperature sensor that will automatically shut off the amp if it reaches dangerous temperature levels and
the LED will be Amber in color.
DC PROTECT (Short Circuit): In the unlikely event the amp should internally fail, the amp will shut down to prevent a DC voltage output to the
speakers or sub and the LED will be Red in color.
Clipping: While adjusting the amplifier the LED may light up Green indicating Pre-Clip, Amber indicating Soft-Clip or Red indicating Clip. These
indicators give the user a chance to identify incorrect settings or high distortion before it is damaging to the equipment allowing them to correct the
volume or settings.
REMOTE: All XXV amps have DIN cable bass remote jacks labeled INPUT. The XXVR-1 Bass Remote Module plugs
into the INPUT jack and allows you to adjust the Bass Boost from 0 to 10dB.
