Warranty

Knoll Systems warrants MA1250 amplifiers sold in the USA and Canada by authorized Knoll dealers to be free of defects in materials and workmanship. This warranty extends for three full years from the date of purchase by the original consumer. Any products returned to Knoll Systems and found to be defective by Knoll Systems within the warranty period will be repaired or replaced at Knoll Systems decision, at no charge. Knoll Systems will not be responsible for the actual cost of installation or removal of the product, nor for any incidental or consequential damages. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation may not apply to you. This warranty gives you specific legal rights. You may have additional legal rights that vary from state to state.

4K and 6K Amplifier

8 and 12 Channel Amplifier

Installation Instructions v1.3

Warning: To be installed and/or used in accordance with appropriate electrical codes and regulations.

Description: The 4K and 6K are members of the long line of Knoll multi-channel amplifiers. Designed primarily for the custom install industry, they are used to power speakers with different or similar sources in multiple rooms. With 8 or 12 channels rated at 50 watts per channels at 8 ohms, these amplifiers pack some serious punch. Each channel has a gain control. The amplifier can be turned on and off via the front panel power switch or via the 12 VDC trigger. 4K channels 3-8 can be linked to channel 1-2 individually using the link switches. 6K channels 3-12 can be linked to channel 1-2 individually using the link switches. 4K and 6K amplifiers designed to meet the amplifier needs of custom installed systems where high-quality sound is a specific requirement.

Key Features:

1.Size efficiency. The 4K has eight power amplifiers and the

6K has twelve power amplifiers each in one 3-1/2” high enclosure. Each power amplifier channel can deliver 50 watts RMS into an 8-ohm load.

2.Automatic protection circuitry. Each amplifier channel is individually and fully protected against low impedance, overheating, overloading, overvoltage and undervoltage. The protection circuitry automatically restores the amplifier channel as soon as its parameter returns to the safe operating area.

3.Individual input gain adjustment. Each channel features an rear chassis input gain adjustment pot to adjust each channel for gain and speaker sensitivity variations.

4.External power on/off. The 4K and 6K can be turned off and on by external controllers using the 12 VDC trigger jack.

5.Stackable 17" chassis with 19” EIA rack version option.

6.Link Feature. Certain installations require that some or all of the stereo channels play the same content. Instead of using Y cords, "link" cascades any or all of channels 2-6 to channel 1 (l/r) on model 6K. With 4K link channels 2-4 to channel 1 (l/r).
