Nice SC4-100 4-Channel Analog Filtering Amplifier


The SC4-100 is designed for flexibility and convenience for the vast majority of distributed audio and home entertainment applications. This single rack-mount chassis is powerful, easy to configure and install.

The SC4-100 delivers up to 100 watts of power to each of four independent channels. It is bridgeable in pairs — doubling the output and enabling 2, 3 or 4-channel configuration.
Additionally, each channel has two selectable analog high pass filters. These filters are critical to optimize the performance of connected satellite speakers or subwoofers, without the hassle of DSP or IP. Independent level control allows you to trim the signal for lower output to small speakers or turn all the way up for max power. The amplifier is stable at a low impedance, so it can drive multiple satellite speakers or a subwoofer from each channel.

Preamp outputs on every channel allow for patching to an adjacent channel or sending the signal to another device.
Audio sensing, and in-&-out triggers add power management convenience. Each channel has a signal and clipping indicator located on the brushed aluminum front panel for easy troubleshooting and signal verification.
Rack ears and tabletop feet are included for mounting options.


Master Power Button – Includes turn-on circuitry

Status Display for Troubleshooting – Channel indicators light green when signal is present and red when clipping

Bicolour Status LED – Illuminates “Blue” when the amplifier circuitry is turned on by the Turn-On circuits, and illuminates “Red” to indicate activation of the amplifier’s built-in protection circuitry

4 Independent Channels Up to 100 Watts @ 8 Ohms – Ample power to drive subwoofers and multiple satellite speakers in a variety of configurations

Bridgeable in Pairs – Flexibility to configure as two, three or four channels

Two Analog Filters Per Channel – Optimized filtering for satellites or subs with a simple switch—no DSP to configure!

Independent Trim – Set levels for each channel to best suit the system
