Memphis Audio VIV1500.1V2

Features

Overview: The Memphis Audio VIV1500.1V2 is a SixFive series mono amplifier. This Class D amp features a compact anodized brushed aluminum chassis with all of the connections on one side for a clean installation. Each amplifier includes a Certificate of Performance with a total RMS power measurement.

Output Power: The amp has the following power output:

• 375 watts RMS x 1 at 4Ω (@ 14.4V, <1% THD)
• 750 watts RMS x 1 at 2Ω (@ 14.4V)
• 1,500 watts RMS x 1 at 1Ω (@ 14.4V)

Optional Wireless Remote: With the optional VIVREMV2 wireless remote, you can control the output level of the VIV750.1V2 remotely. The remote will automatically pair with the amplifier, and offers a control range of 0 to -26dB. The remote has a rechargeable battery with an estimated battery life of 1000 hours.

Protection Circuitry: The amplifier features built-in circuitry to protect the amplifier against short circuit, overheating, and over/under battery voltage. A Protect LED on the side of the amplifier will glow red when the amplifier shuts down due to any of the above causes.

Sub-Sonic Filter: The Sub-Sonic Filter provides a cutoff point for lower frequencies that cannot be cleanly reproduced by the subwoofer, and may cause damage to your speakers and waste amplifier power. The Sub-Sonic Filter is variable from 10Hz to 80Hz, with a slope of 24dB per octave.

Bass Boost: Memphis Audio's M-Equalization lets you fine tune the bass output to your subwoofers. (It's a single band parametric equalizer.) You can adjust the center frequency, Q (bandwidth of the boosted signal; higher Q results in a sharper cutoff of the frequencies above and below the selected center frequency), and amount of boost at the center frequency.

Controls: The amplifier features a hinged top plate where the following controls are accessed:

• Gain: rotary control; continuously variable, labeled 0 to 10
• Sub-Sonic Filter: rotary control; continuously variable 10-80 Hz; labeled at 10 Hz, 25 Hz, 45 Hz, 70 Hz and 80 Hz; 24 dB/octave slope
• Low Pass Crossover: rotary control; continuously variable 50-200 Hz; labeled at 50 Hz, 70 Hz, 100 Hz, 160 Hz and 200 Hz; 48 dB/octave slope
• M-Equalization:
  • Center Frequency: rotary control; continuously variable 20-80 Hz; labeled at 20 Hz, 30 Hz, 45 Hz, 60 Hz and 80 Hz
  • Q: rotary control; continuously variable; labeled 1-5
  • Bass Boost: rotary control; continuously variable 0-18 dB
• LED Color: rotary control; sets the color of the logos on the top of the amplifier and the light strips along the sides; seven LED colors to choose from
• Input Level: 2-position switch:
  • Lo: line-level source; 200mV to 5V input range
  • Hi: speaker-level source; 400mV to 10V input range
• Auto Turn On: 3-position switch:
  • 12V: using a +12 volt remote turn-on wire
  • DC: DC Offset; speaker level input only
  • Audio: Audio Signal Sense; speaker level or line level input

Note: If the Auto Turn On switch is set to DC Offset or Audio, you can use the REM terminal to send a +12 volt turn-on signal to additional amplifiers.

Connections:

• Power/Ground/Turn-on: set screw terminals; power and ground terminals accept bare wire up to 1/0-gauge (1/0-gauge amplifier wiring kit with an in-line 100-amp fuse on the power wire within 18" of the battery recommended); REM set screw terminal accepts up to 10-gauge wire (18-gauge remote lead is sufficient)
• Signal Input: stereo RCA jacks; preamp or speaker level input
• Line Output: stereo RCA jacks for sending the audio signal to a second amplifier
• Speaker Output: two pair if set screw terminals, internally shorted together, for easily connecting two subwoofers; accept up to 10-gauge wire
