[. . . ] Binding Post Speaker Outputs Connectors are 5-way binding posts for maximum versatility. XLR and ¼" Inputs Low impedance, balanced inputs accept a male XLR connector or a ¼" TRS phone jack. Note: The ¼" input accepts either tip/ring/sleeve or tip/sleeve phone connectors. Run this in either bridged mono or in stereo depending on the position of the switch. Clip Limiter When an audio signal drives an amp's output circuit beyond its power capability, its clips, flattening the peaks of the waveform. A clip limiter detects this and quickly reduces the gain to minimize the amount of overdrive. The PS3402 has a clip limiter built in and you can switch it on or off as shown at the rear panel. Input Filter (Low Cut Filter) The switchable low-frequency (LF) filter rolls off signals below either 30Hz or 50Hz. This improves performance by eliminating subsonic cone motions making more power available for the speaker rated frequency range. The filters frequency setting for both channels is controlled by the 30Hz/50Hz slide switch. This heavy duty power cord uses a 20 amp connector where one blade is perpendicular instead of parallel to the other blade. This is a safety feature to prevent you from plugging into a circuit less than 20 amps. The outlet receptacle will have one T shaped blade insert that will accept both types of connectors. If you do not have this type of receptacle, please contact your local electrician for an upgrade. Do not obstruct air flow to this opening. 6 V Connecting Your System A. MOUNTING The PS3402 Power SourceTM is designed for standard 19" rack mounting. In addition, the amplifier is provided with sturdy no-skid rubber feet for secure table top or stacked operation. When rack mounting one or more amplifiers or when mounting in combination with other equipment, be sure to allow adequate front and rear ventilation to avoid possible heat related damage to your PS3402 Power SourceTM or other rack mounted items. B. OPERATING PRECAUTIONS Your SoundTech PS3402 Power SourceTM power amplifier is well protected from any external faults. Safety Instructions Read and follow all of the safety warnings in this manual. . Grounding Your power amplifier is supplied with a three conductor, grounded power cord and plug. Do not use a ground lift adapter or otherwise attempt to defeat the ground on the plug. [. . . ] Although connecting your speaker system out of phase using the wrong polarity will not damage your speakers, it will affect the quality of sound. When using bare wire connections, be sure that your connections are "clean. " If any strands of wire from one connector are allowed to touch the adjacent connector, damage to your amplifier and sound system could occur. 9 Connecting Your System F. XLR Input Jacks Electronically balanced inputs accept a standard XLR male connector. 1/4'' Phone Input Jacks Accepts a balanced or unbalanced line level signal. [. . . ]
