Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Inputs, Outputs and Controls
Class A 100% Discrete Driver
Circuitry Topology: The preamp stages
use Class A topology for low distortion and a high damping factor; the result is
tight, controlled bass.
Pure N-Channel Design:
The pure N-channel design is more linear than typical N-Channel designs, so the
speaker you connect to the amplifier will be better controlled. The signal
travels through fewer parts so the signal-to-noise ratio is enhanced, the power
rating is better, and the amp runs louder, longer.
Internal Crossovers: The
amplifier has two built-in crossovers, one for the speaker outputs and one for
the preamp outputs. Each crossover can be set for high-pass or low-pass
operation, or it may be turned off for full-range output. If you select
high-pass, the crossover slope is 12dB/octave. If you select low-pass, the
crossover slope is 24dB/mono. Each crossover is adjustable from 40-200Hz.
There is one set of isolated preamp outputs for adding another amp. The preamp
outputs can be set for high-pass, low-pass, or full-range operation.
EBC (Electronic Bass Control)
2: This amplifier includes an
Electronic Bass Control Port that will accept the cable from an optional EBC.
When an EBC is connected, you have access to an additional 3dB of gain and 23dB
of attenuation from the driver's seat. If the optional EBC is installed, the
bass level will be able to be adjusted to overcome noise and other interference.
With EBC 2 multiple compatible amps can be controlled.
Intelligent Surface Mount
Technology: This amplifier features
substantially shorter internal and external lead lengths, reducing stray
capacitance and inductance, which results in cleaner and more accurate musical
reproduction with less noise interference.
Protection Circuit: The protection
circuit makes sure you amp is operating within safe parameters for maximum power
Turn-on/Turn-off: A circuit that
prevents turn-on/turn-off "thump" is included to eliminate turn-on/off
rubber Iso-Feet are attached to the amplifier. The rubber feet let you mount the
amp securely, while preventing the mounting screws from coming into contact with
the amp's chassis; this helps prevent ground loops.
terminals are nickel-plated, heavy-duty screw terminal connectors.
MTX tests each amplifier, and the technician records the "actual"
power output on the Certified Performance Certificate included with each amp.
The amp must meet or exceed the rated specification in order to leave the
Outputs and Controls
Left Side of the Amplifier
- Left and Right Gain Controls:
the gain controls allow you to
match the input sensitivity of the amplifier to the particular source unit
you are using
- Thunder EQ Control: a rotary
control that allows you to set the bass boost applied to the speaker output
signal. The bass boost is centered at 40Hz and is adjustable from 0-18dB.
