WARNING

11. Refer all servicing to qualiﬁed service personnel. Servicing is required when

the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

12. Exposure to extremely high noise levels may cause permanent hearing loss.

Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufﬁciently intense noise for a period of time. The U.S. Government’s Occupational Safety and Health Administration (OSHA) has speciﬁed the permissible noise level exposures shown in the following chart.

According to OSHA, any exposure in excess of these permissible limits could

result in some hearing loss. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels use hearing protectors while the equipment is in operation. Ear plugs or protectors in the ear canals or over the ears must be worn when operating the equipment in order to prevent permanent hearing loss if exposure is in excess of the limits set forth here:

Big Knob Passive Monitor Controller

Big Knob Passive is the perfect monitoring tool as a level control for a home / project studio or integrated as part of a larger studio. There are many great things about the Big Knob Passive, but one of the features is no need for power...it can be placed anywhere to your heart’s content! After you’ve decided on a spot, it’s time to make connections.

In this example, a computer installed with your favorite DAW is connected to the Source Input A L/R jacks. The Source Input B jacks may accept 1/4" inputs and an 1/8" stereo input. If both inputs are connected simultaneously, the 1/8" stereo line input will take priority over the 1/4" connection. In this case, we hooked up a smartphone to the 1/8" stereo line input jack.

The output section is as straightforward as the input section. Here we connected a pair of XR Series studio monitors to the Mon Output A L/R jacks and a pair of MRmk3 Series studio monitors to the Mon Output B L/R jacks.

Now that connections have been made, the fun begins! The top panel has a variety of switches, buttons and something else...what was it? Oh yeah, a BIG knob, dead center! These allow you to select between the inputs, outputs, control levels and more. Descriptions of the Big Knob Passive features starts on the next page...
