SpeakerCraft 4 Channel Amplifier

Real World Power 
The SC4-100 deploys four independent channels of up to 100 watts per channel peak and over 70 watts per channel continuous with an 8Ω load and all channels driven. The power nearly doubles when presented with a 4Ω load. The SC4-100 delivers more than enough power for the vast majority of architectural and outdoor speakers. 
 

Bridgeable In Pairs
Each bridged pair delivers 200 watts of rated power with an 8Ω load, and all channels driven. This enables configuration as a 2 x 200w two -channel amp, or a 1 x 200w + 2x 100w 3 channel amp for exceptional flexibility in the field. It is designed to operate with a wide range of impedance loads, so it can drive sub woofers and multiple satellite speakers simultaneously in a variety of configurations.

Analog Filtering
Rather than implementing complex and costly DSP which can degrade the signal, and is difficult to configure, the SC4-100 features two selectable analog audio circuits per channel that meet the filtering demands for most installations with the flip of a switch.

Each channel has a choice of two high pass filters. One rolls off at 20hz and is designed for subwoofers and large full range speakers with extended bass capabilities and will filter out in audible low frequencies and rumble that can overwork subwoofers and impede optimum performance in the audible range.

Freedom From Fan Noise
The oversized heat sinks inside the 2-channel amplifier allow the amplifier circuitry to stay cool even when operating into low impedance loads without the distracting noise created when using fan-cooled amplifiers.

Independent Level Controls
Each amplifier channel features an independent level control enabling precise volume matching the rest of the system. These level controls can also limit volume to prevent abuse of the system.
 

Reliable Connections
The SC4-100family features gold plated stereo inputs, cascade stereo outputs, and five way binding posts to ensure perfect connections without corrosion for years to come.

Turn-On Modes
The SC4-100 features three turn-on modes:
1. Music sense, 2. External voltage trigger, 3. Manual turn-on via the front panel switch. You can configure a SC4-100 to interface with any kind of system and have the unit automatically turn on.

Automatic Protection
The SC4-100 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.

Status Display For Troubleshooting
Led indicators on the front panel indicate power- active status, and a protection warning. Channel – signal present (green) clipping (red). With a glance at the front panel, key information is presented.

Control Output
A 12-volt dc output is provided whenever the amplifier is on, allowing you to operate voltage triggered devices like motorized screens and curtains.
