Turn amplifier ‘off’ when plugging in or unplugging input and speaker cables!!! The ST3140 is equipped with raised feet so that continuous ventilation can be maintained. They help to maintain acoustic feedback into the amplifier at a minimum.
The ST3140's purpose and function The ST3140 is a compact, very efficient, three channel power amplifier. It is designed to be used in all types of audio or audio/video systems. The ST3140 utilizes high quality electronic circuitry to achieve an environment wherein a detailed, transparent, and highly musical sound can be realized.

The preamplifier’s control output, such as is provided with B&K series preamplifiers, can be utilized to provide a control signal to the ST3140. If more than one amplifier is being controlled, the control signal can be extended to include each successive unit by simply running a 3.5mm mini-jack cable from the CTRL OUT connector of the first amplifier to...
If the control function is desired, each unit in the system must remain connected at all times and the control must be enabled. To enable the control function, the CTRL ENABLE button must be out for each controllable amplifier in the system. For more information on the amplifiers output status under various control conditions, refer to the table below.
Five way binding posts are provided. One pair for each channel. They are designed to accept a banana-type plug or spade lug connector (shown below) and are color coded for easy identification. The red (+) post should always be connected to the speakers (+) jack.
Here is a typical input setup: There will most likely be a number of cables involved in the installation of your home entertainment system. Pre-planning is essential in order to maximize system efficiency. We recommend the following as a means of helping you reach that goal: Make a diagram of your proposed system by laying out the relative location of each component in the system.
Before doing anything, ensure that the power switch on the amplifier’s front panel is in the ‘off’ position. Again, it is recommended that you locate a separate AC power outlet for the amplifier, one that is component in the system or any other house hold component. This will eliminate the possibility of the amplifier ‘modulating’...
