IMPORTANT SAFETY INSTRUCTIONS! Please read this very carefully before operating this unit Read ALL instructions carefully before using this unit. Do not operate this unit near water, in the rain or where there is moisture. If this warning is ignored a serious electrical shock or death may occur. Do not attempt to service this unit. No user serviceable parts inside. Refer servicing to qualified, ISP approved service personnel.
Caution: Exposure to extremely high noise levels can cause permanent hearing loss. The VMAX speaker system is capable of producing in excess of 124db SPL at 1 meter. Continued exposure to noise levels in excess of 90db may cause permanent hearing loss. Below is a chart of the OSHA (Occupational Safety & Health Administration) regulations for Occupational Noise Exposure.
PLACEMENT The VMAX is designed to sit on the floor or stage in a flat position and can also be used as a top box in a standing position or pole mounted. Do not position or mount the cabinet where it can tip over and fall on someone. Do not attempt to ‘fly’ (suspend by cables, chains, ropes, etc.) the cabinet. Do not attempt to suspend the cabinet from the handles. It was not designed for flying. Position it only on a flat, stable surface where it is not in danger of tipping over or falling.
4. MIC/LINE1 BALANCED XLR INPUT-This female XLR connector provides the input for channel 1. 5. LINE3 GAIN CONTROL- This control determines the gain of the MIC/LINE channel 1. When using this input for a line level input, the gain should be set a minimum. The Microphone preamp provides up to 50db of gain. 6. LINE3 BALANCED XLR INPUT-This female XLR connector provides the input for channel 3. 7. MIC/LINE2 GAIN- This control determines the gain of the MIC/LINE channel 1.
Using multiple VMAX cabinets in parallel Multiple cabinets can be added in parallel by feeding the link output of one cabinet to the line input of a second cabinet. You can chain as many cabinets together as desired in this configuration. You will need to use either the Line1 or Line2 input when using the VMAX in parallel in order to have an output signal at the link output. When paralleling multiple cabinets you will need to connect the link output to the Line1 input of the next cabinet.
Note: when using the line input(s) on the VMAX keep the Microphone input level controls at minimum to avoid any increase in input gain noise. It is recommended to match the input sensitivity of the VMAX speaker with the output level of the external mixer. Increasing the gain of the VMAX input may cause clipping of the input section of the VMAX speakers. It is recommended to start with the gain at minimum and increase the VMAX input sensitivity as needed. FUSE REPLACEMENT 1.
THERMAL CONDITIONS The ISP VMAX is capable of producing in excess of 400 watts RMS at full power. This generates heat that must be dissipated in order to maintain reliability and insure the amplifier components stay within their operating temperature specs. To accomplish this, the amplifier is mounted on a heatsink that is exposed on the side of the cabinet. As the heatsink gets hot air will flow over the fins on the heatsink by convection.
