User manual PEAVEY 600S

[. . . ] INTRODUCTION Congratulations on your purchase of an Architectural Acoustics ICATM (Industrial Contractor Amplifier) from Peavey Electronics. Please read this manual carefully, especially the IMPORTANT SAFETY INSTRUCTIONS on page 18. It contains information vital to safe operation of the power amplifier. Also, please fill out and return the enclosed product registration card. [. . . ] if the cable shield is connected to the signal ground only , it will be clamped to +/- 0. The ICATM Series incorporates protection features derived from Peavey's extensive experience with reliability. The amplifiers are ruggedly built from high-quality components and feature comprehensive protection circuits to protect your amplifier from those "real world" occurrences. CLIP LIMITING At the amplifier's full power, or clipping point, the channel gain will automatically be reduced, guarding the loudspeakers against damaging high power and continuous square waves that would otherwise be produced. this is indicated by illumination of the CLIP LED. Normal program transients will not trigger Clip Limiting, only steady or excessive clipping will. operation is virtually transparent in use and full signal bandwidth is maintained. LOAD FAULT CORRECTIONTM LFC is an innovative circuit that will instantaneously reduce channel gain to allow the amplifier to operate at a safe level into an abnormal load. In addition, if extreme low impedance or a short circuit is encountered during high signal level conditions, the amplifier's output relay will open. FADE-IN PROTECTION This feature operates every time the amplifier is turned on, or after a protect condition. During turn on, the amplifier goes into protect mode and leaves the speaker load disconnected until the amplifier determines that the operating status is normal. , DC, turn-on bursts, subsonic, incorrect load or short Connectors: 8-pin plugable signal input, 4-pin plugable sequential power, 4-terminal barrier strip, IEC AC power connector Construction: All steel; 16 ga.

[. . . ] ) This product should be located so that its position does not interfere with its proper ventilation. It should not be placed flat against a wall or placed in a built-in enclosure that will impede the flow of cooling air. This product should not be placed near a source of heat such as a stove, radiator, or another heat producing amplifier. Connect only to a power supply of the type marked on the unit adjacent to the power supply cord. [. . . ]
