CEA-2006 Compliant: CEA-2006 is a system of testing and
measurement methods for mobile audio amplifiers. This voluntary standard advocates
a uniform method for measuring an amplifier's RMS power output and signal-to-noise
ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and
the RMS power output is measured into a 4Ω load, with 1% or less Total Harmonic
Distortion plus noise (THD+N), and over a frequency range of 20 Hz to 20 kHz (for
full range amplifiers). Signal-to-Noise ratio is measured in weighted absolute
decibels (dBA) at a reference of 1 watt into 4Ω. CEA-2006 standards allow
consumers to compare amplifiers on an equal basis. Using CEA-2006 criteria, the
Sony XM-N1004 is rated at 70 watts RMS x 4 channels, with a 93 dBA signal to noise
Pulse Power Supply: The amplifier utilizes a Pulse Power
Supply system to regulate the fluctuating voltage received from the car's
Crossover: The front and rear amps have independent crossovers:
- Front: a three position switch
sets crossover to low pass, off (full range), or high
pass; the crossover point is fixed at 80 Hz and the
slope is 18 dB/octave when set to low pass, 12 dB/octave
when set to high pass
- Rear: a two position switch turns
the low pass filter (LPF) on/off; the crossover point
is fixed at 80 Hz and the slope is 18 dB/octave
Power Connections: The power, ground, and remote turn-on
screw terminals are 0.35" wide. A Phillips-head or flat blade screw driver
(not included) is required to tighten/loosen the terminals. A protective cover
is included for the power/ground/remote terminal block.
Speaker Connections: The speaker screw terminals are 0.35"
wide. A Phillips-head or flat blade screw driver (not included) is required to
tighten/loosen the terminals.
RCA Input: The amplifier has two pair of stereo RCA line
level inputs (front left/right and rear left/right).
Fuse: The amp is protected by two 25-amp ATO blade fuses.
