  • Page 2 DESCRIPTION The IC’s that were developed primarily for the instrumentation market had many shortcomings when used in high quality audio applications. The lack of audio related specifications, crossover distortion, high noise for low source impedances, limited output capability and limited gain bandwidth product forced many compromises when used in high gain audio systems.
  • Page 3 MICRO"P, use the proper ground for each channel. The L1000 will accept input audio to +24dBm bridging (12.5 Vrms). Inputs are protected by clamping diodes for signal swings exceeding ±41 Vp-P. Output wiring is indicated on the rear panel label. H1 outputs are in phase with each other and with the input signal.
