Sony Mobile ES amplifier XM-1ES

CTA-2006 Compliant: CTA-2006 is a system of testing and measurement 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 amplifier power uses a DC input voltage of 14.4 volts and the RMS power output is measured over a frequency range of 20 Hz to 20 kHz (for full range amplifiers), with 1% or less Total Harmonic Distortion plus noise (THD+N). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4-ohms. CTA-2006 standards allow consumers to compare car amplifiers and receivers under the same conditions (apples to apples).

CTA-2006 Specifications:

• Power Output: 600 watts RMS x 1 into 4-ohms
• Signal to Noise Ratio: 77 dBA (measured at 1 watt into 4-ohms)

Other Specifications:

• Power Output:
  • 2-ohm: 1,000 watts RMS x 1 (14.4 volts, =1.0% THD+N)
• Signal to Noise Ratio: 100 dB (at rated power output, 4-ohms)

Amp Overview: The Sony XM-1ES is a Class D mono subwoofer amplifier. Its Class D design and aluminum chassis offer efficient dissipation of heat for reliable performance.

Speaker-Level Inputs: The RCA inputs will accept either speaker-level or line-level signals from your car's head unit. A speaker-level signal is connected to the RCA inputs using a speaker wire to RCA adapter (sold separately).

Auto Turn-on: When using a speaker-level input, the amp will turn on automatically when it senses the input signal from most head units.

Protection Circuits: The amplifier is equipped with protection circuits and turns off in the case of speaker short circuit, thermal overload, or DC output.

Controls

Turn-on: 2-position switch:

• Remote: amp turns on when a +12 volt signal is applied to the remote terminal
• Signal: amp turns on when it senses a speaker-level input

Input Voltage: 2-position switch:

• Low: input sensitivity range is 200mV to 8V; used for preamp-level inputs
• High: input sensitivity range is 3V to 16V; used for speaker-level inputs

Input Sensitivity (Gain): Input sensitivity is adjusted with rotary a dial; the range depends on the input voltage switch setting.

Input Mode: 2-position switch:

• 1: uses only input 1
• 1+2: inputs 1 and 2 are combined and the summed signal feeds the amplifier stage

Line Out Mode: 2-position switch:

• Thru: inputs 1 and 2 feed line outputs 1 and 2 respectively
• All: both inputs are combined and the summed signal feeds both line outputs

Crossover: The amp features a 24dB per octave low-pass crossover. The crossover point is continuously variable from 50 to 500 Hz.

Subsonic Filter: There is also a 24dB per octave subsonic filter to remove frequencies your sub can't reproduce. The cutoff frequency is continuously variable from 5 to 50 Hz, and the subsonic filter can be turned off if you prefer.

Remote Control: The included wired remote control lets you control the output level from the driver's seat. The small control module can be mounted on the console or dash with the supplied bracket and screws. The remote measures approximately 1-1/8" in diameter and 1-3/8" tall.

Connections

Power Input: Set-screw terminals are provided for connecting the power and ground cables. The terminals accept up to 4-gauge wire (4-gauge minimum recommended). The set screws are tightened/loosened with the included 2.5mm Allen wrench.

Remote Turn-on: The remote turn-on set screw terminal will accept up to 8-gauge wire. The set screw is tightened/loosened with the included 2.5mm Allen wrench.

Speaker Outputs: There are two pair of speaker outputs internally shorted together, making it easy to connect two subwoofers wired in parallel. These set screw terminals accept up to 8-gauge wire and are tightened/loosened with the included 2.5mm Allen wrench.

Signal Input: The amplifier has one pair of stereo RCA inputs. If no line-level signal is available, you will needSpeaker wire to RCA adapters.(sold separately) to connect the amplifier to the source unit via speaker wires.

Line Outputs: There is one pair of RCA preamp outputs, useful for adding another amp without running another set of cables. The preamp outputs are not affected by the crossovers or input sensitivity setting on this amp.

Fuses: The amp has four 25-amp ATO fuses.

Remote: The included wired remote plugs into the RJ-14 jack.
