About the SpeakerCraft SC2-150

Dave Bar

Top-notch power and performance

Whether you're using the SpeakerCraft SC2-150 as a part of a multi-room audio system or as the amplifier in your main listening room, you'll find that it delivers plenty of pristine, dynamic stereo power. Its high-current design allows it to handle unusual and challenging loads with ease, including the ability to safely drive up to three pairs of directly connected 8-ohm speakers at the same time. And it's not just all muscle. SpeakerCraft uses high-quality parts throughout to ensure that you'll always get top-notch audio performance. Cutting-edge, independent power supplies for each channel prevent cross-talk interference, ensuring clean, spacious sound. Oversized heat sinks keep the SC2-150 cool even when driving heavy loads, eliminating the need for a noisy cooling fan and guaranteeing silent operation.

Installer-friendly features

SpeakerCraft knows what it takes to stay competitive in the world of custom installation. That's why their amps include features that make them easy to integrate. You get three separate turn-on modes to bring the amp to life, plus a 12-volt DC control output to activate other devices such as motorized screens and curtains. Independent level controls for each channel allow precise volume matching to the rest of the system, and can also be used to limit volume to prevent speaker damage. Handy cascade audio outputs let you daisy-chain multiple amps together. And you can even combine its two channels into one to create a mono-power beast — a great option for power-hungry outdoor speakers.

Features

2-Channel Power Amplifier: The SpeakerCraft 2-channel SC2-150 power amplifier has been specifically created to solve the problems of interfacing with different brands and models of equipment, different acoustic environments in different rooms, and different kinds of applications like home theater, stereo, and background music. The SpeakerCraft 2-Channel power amplifier brings extremely high current power to a custom installed A/V System in an extremely convenient way.

  • High Quality Audio Circuitry: The SpeakerCraft SC2-150 power amplifier employs audio circuitry constructed with the finest parts available, including 1% metal film resistors, high quality capacitors and oversized heat sinks for clear and uncolored sound.
  • High Current Design: The high current design of the SpeakerCraft SC2-150 Amplifier assures that even unusual and reactive loads are handled with ease. Cutting-edge digital power supplies provide more than ample current to your system.

Stereo & Bridged Applications: The SpeakerCraft 2-channel SC2-150 power amplifier can be setup in a stereo or bridge configuration. You'll get tremendous bass and dynamics from your connected speakers in either configuration.

  • 8-Ohm Stereo: The SpeakerCraft SC2-150 power amplifier delivers 150 watts per channel at 8 ohms.
  • 4-Ohm Stereo: The SpeakerCraft SC2-150 power amplifier delivers 270 watts per channel at 4 ohms.
  • 8-Ohm Bridged: The SpeakerCraft SC2-150 Amplifier can be operated in a bridged mono configuration. In this configuration, the SC2-150 delivers 550 watts at 8 ohms. Bridged mode is perfect for subwoofer, outdoor speaker, or any applications requiring high power output.

Inputs/Outputs: The SpeakerCraft 2-channel SC2-150 power amplifier offers analog stereo RCA inputs & outputs, plus binding post speaker terminals.

  • RCA Inputs: The stereo RCA input allows you to connect an external analog audio source, such as your CD/SACD player, Blu-ray/DVD player, HT/Stereo receiver, or other analog source device.
  • RCA Outputs: The stereo RCA output allows you to connect to another amplifier's analog stereo input. This output is not buffered; if you wish to daisy-chain more than five SpeakerCraft 2-Channel amplifier amplifiers you will need a buffered distribution amplifier (sold separately).
  • Speaker Outputs: The SpeakerCraft SC2-150 amplifier is fitted with gold-plated, binding posts for each channel. The binding-post terminals will accept bare-wire (up to 10AWG), pin-connectors, and banana plugs (dual or single).

Independent Circuitry: Each channel of the SpeakerCraft SC2-150 power amplifier features its own independent power supply and level control.

  • Independent Power Supplies: Each channel of the power amplifier is powered via its own independent
    power supply. This increases the isolation between channels and eliminates cross talk, guaranteeing you absolute silence to the backdrop to your music.
  • Independent Level Control: Each amplifier channel features an independent level control enabling precise volume matching
    to the rest of the system. These level controls can also limit volume to prevent abuse of the system.

Turn-On Modes: You can configure the SpeakerCraft SC2-150 amplifier to interface with many kinds of systems and have the unit automatically turn on. The SC2-150 amplifier features three turn-on modes - Music Sense, External Voltage Trigger (3-24VAC/DC), & Manual Turn-on via the front-panel switch.

  • Manual Switch: Select Manual mode when you wish to manually turn the amplifier on and off by using the front-panel power switch.
  • Music Sense: Music Sense mode turns on the amplifier when the amp's main input receives an audio signal. Once the signal stops, the amplifier waits 3 minutes and then turns itself off.
  • External Voltage Trigger: Use the External Voltage Trigger mode if you prefer the amplifier turn on when it receives voltage (3-24V) from an external source and turn off once that voltage has stopped. The voltage source must be connected to the trigger input jack (3.5mm) on back of the amplifier.

Control Output: A 12 Volt DC output (3.5mm) is provided whenever the amplifier is on, allowing you to operate voltage triggered devices like motorized screens and curtains.

Protection Circuitry: The SpeakerCraft 2-channel amplifier provides sophisticated auto-protection circuitry and a "no-fan" cooling system for dependable and silent operation.

  • Auto Shut Off: The 2-channel amplifier is equipped with sophisticated protection circuits. In the unlikely event that a problem occurs, the amplifier shuts itself off. When conditions return to normal, regular operation resumes.
  • No Noise Cooling System: The oversized heat sinks inside the SC2-150 allow the amplifier circuitry to stay cool even when operating into low impedance loads without the distracting noise created when using fan-cooled amplifiers.

LED Indicators: LED indicators on the front panel indicate Power, Active Status, and a Protection Warning.

Rack Mountable: The power amplifier includes a set of rack ears for rack mounting applications. Its compact low profile design requires only a single rack space (1U).

Customer Q&A

Q
Can I connect two fronts, two rears and a center channel to this amplifier? I have a Pioneer SC-81 receiver.

A
The SpeakerCraft SC2-150 is a stereo/2-channel amplifier; so it would only be able to power a single pair of speakers. You'd need an amp with at least 5-channels to power two fronts, two rears and a center channel speaker. I hope that helps. My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=159
