Volume control enables the users to control the audio output level of the sound system from multiple locations. 

• Balance an unbalanced audio line at its source
• Bridge a balanced audio line
• Distribute audio to several destinations
• Remote control audio sources or audio level
• Add automatic gain control or compression where it is needed in a system
• Preamplify a microphone at the microphone location to drive line level
• Multiple location remote control capabilities
• Provide electronic attenuator

• Inputs --- 10 K Ohms balanced or unbalanced line level
• Frequency response --- 10Hz to 25 KHz
• Total harmonic distortion --- <0.020% (20Hz to 20KHz)
• Ramp rates --- 3 seconds to 10 seconds approximately
• Audio outputs --- balanced @ 150 ohms to drive hi and low impedance line
• Ramp outputs --- 0 to 10 V, DC with ground reference
• Power requirement --- low voltage (24 volts approximately)
• Up and down selection pushbutton or dial
• Three years warranty on parts and labor, one year required
