Definition

Sample rate refers to the number of times per second an audio signal is measured (or "sampled") when converting between analog and digital. It's expressed in kilohertz (kHz) — so 44.1 kHz means 44,100 samples per second. Higher sample rates capture more snapshots of the waveform, and in theory, more accurately represent the original analog signal.


Common sample rates you'll encounter:


  • 44.1 kHz: the standard for CD audio and most music streaming

  • 48 kHz: the standard for video, broadcast, and professional audio production

  • 96 kHz / 192 kHz: high-resolution formats, common in modern DAWs and audiophile use. 


Debate! And Controversy!! 

Audibility of sample rate is one of pro-audio's long-running conversations. Experienced users land on both sides of this topic. Here’s some information to help our customers understand how sample rate interacts specifically with DSP-equipped speakers like ours.


Sample Rate and Your Kali Monitors

Kali LP and IN Series monitors process audio internally at 48 kHz. This means that regardless of the sample rate of your incoming signal (whether it's 44.1, 96, or 192 kHz) it will be converted to 48 kHz within the DSP before it reaches the drivers.


Notes:


  • Any signal above 48 kHz will be downsampled, but that said, the higher the quality of the incoming signal the better! 

  • Every A/D or D/A conversion involves some degree of change. Even when two devices share the same sample rate, there is no perfectly lossless 1:1 transfer. This is true of every DSP-equipped speaker on the market, not just Kali.

  • You can avoid additional conversion stages by using a fully analog signal path after your DAC, but this usually comes with real tradeoffs in cost, flexibility, and the precision that DSP-based tuning and optimization provides.


What Actually Matters More

Overall system design has a far greater impact on what you actually hear than sample rate alone. Frequency response, distortion characteristics, driver quality, crossover design, and most importantly, your room acoustics will shape your listening experience in ways that dwarf any differences attributable to sample rate.


In real-world monitoring conditions, the 48 kHz processing in your Kali monitors isn’t going to be a limitation. 


TL;DR

Kali LP and IN Series monitors process audio at 48 kHz so higher sample rates are converted internally. In practice, this isn't going to be a limitation. The SM-Series can process higher sample rates up to 192kHz. Speaker design, tuning, and your room will have a far greater impact on sound quality than sample rate ever will.
