Morel MPS 2.150 LIMITED 2-Channel 300W Class AB Amplifier

Morel MPS 2.150 Limited

Gold-plated sound

If you're looking for high fidelity as well as high power and style, Morel's MPS 2.150 Limited 2-channel amplifier will deliver. Developed to commemorate Morel's 45th anniversary, this sleek amplifier features gold-plated wiring connections, a specially designed internal signal path, low-noise Class AB architecture, low tolerance surface mount electronic components, and computerized thermal control — all to give you the most accurate musical reproduction possible, along with pure, clean power.

High-performance options for high-performance speakers

The MPS 2.150 Limited 2-channel amplifier can power a pair of high-performance speakers with 150 watts RMS each. It can also be used to power a subwoofer with up to 300 watts RMS when bridged in one-channel mode. A unique feature of this amp is that you can select between two voltage modes in order to optimize the outputs for different speakers — High Power for 4-ohm speakers, High Current for 2-ohm speakers, or a 4-ohm sub when the amp is bridged.

Pure signal path

The MPS 2.150 Limited doesn't have any audio filters to alter the purity of the signal being amplified. The amp depends on being driven by a high-quality receiver or digital processor to deliver the cleanest amplified signal possible, with no added coloration or distortion. Separate gain controls for the two channels allow for customized applications, like when powering a tweeter and a woofer in an active setup.

Controls:

• Input Level: the two channels have independent input level controls; labeled min/max, the voltage range depends on how the input voltage switch is set (high/low)
• Turn On Mode: three position switch to set how the amp is turned on; Remote (+12 volts on the remote terminal), Signal (senses an input signal voltage), Offset (reads a DC offset in the input signal; typically only used when "Remote" isn't an option and the "Signal" setting doesn't work reliably)
• Input Voltage:
  • Low: 200mV-4V; typically used with line level outputs from an after-market source
  • High: 400mV-8V; typically used with speaker level outputs

Connections

• Signal Inputs: the amplifier has one pair RCA jack inputs; accept preamp or speaker level signals
• Speaker Outputs: two pair of set screw terminals; accept up to 10-gauge wire
• Remote Turn-On: set screw terminal; accepts up to 10-gauge wire
• Power and Ground: set screw terminals; accept up to 4-gauge wire; 8-gauge minimum recommended by Morel
