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 with 1% or less Total
Harmonic Distortion plus noise (THD+N) 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 allows
consumers to compare car amplifiers and receivers on an equal basis. Using
CEA-2006 criteria, the JVC KS-AX3201D is rated as follows:
- Power Output:
- 4Ω: 250 watts x 1-channel
- 2Ω: 400 watts x 1-channel
- Signal to Noise Ratio: 60 dBA
Crossover: The low-pass crossover has an 18 dB/octave slope and
the crossover point is continuously variable from 50 Hz to 200 Hz. The crossover
cannot be bypassed (it's not a full range amp).
Power Connections: The power and ground terminals are nickel-plated
screw terminals. They will accept spade connectors or ring terminals up to 0.5"
wide. The remote turn-on terminal will accept a spade connector or ring terminal
up to 0.35" wide.
Speaker Connections: The speaker output (one pair) is also
nickel-plated screw terminals and will accept spade connectors or ring terminals
up to 0.35" wide.
Speaker Level Input: A speaker level input harness is
included, making it easier to add the amplifier to a factory radio or to a
receiver with no preamp outputs.
Line Level Output: The amplifier has a pair of RCA line
level outputs to feed another amplifier.
