24 Channel Stereo Summing Circuit

• 50 Single-ended line-level inputs, 25 for left, 25 for right
• 2 Single-ended line-level outputs, 1 for left, 1 for right
• Active Combining Network topology, with second inverting stage
• DC servo circuits – No electrolytic capacitors in the audio path
• Summing is done on the pc board, resulting in minimal noise pickup from external sources
• Adjustable gain
• Ability to daisy chain for more inputs
• 1kHz THD+N at +20dBu < 0.0006%, unity gain, one input, unused inputs connected to ground
• THD+N less than 0.0014%, +4dBu, 20-20 kHz, unity gain, 20 kHz BW, one input, unused inputs connected to ground
• Frequency Response: -3dB > 200Khz
• Standard summing resistors are 12k-ohm, but can be ordered with any available value wanted
• Size: 4-inches x 2.6-inches

• Summing circuit for new designs
• Replacement summing circuit for existing products

• +/- 12-Volts to +/- 19-Volts power supply
Installation should be done by a qualified technician
