Ohr-1: Welcome to the Club

Lets get you started.

1. Push to start

Turn on and off using the push button on the front.

2. Charging

Charge via the USB-C port on the back of the Ohr-1. The Ohr-1 is fully compliant with the USB-C specification and can be plugged into your computer or a power adapter.

The Ohr-1's battery lasts for ~100hrs of continuous use.

3. Indicator Light

There is a power indicator light in the bottom-right corner of the display.

Fast flash = low battery (~3 hours left).

Slow flash = charging.

4. Level Guide

The threshold for hearing damage is 85dB(A). That is when the Ohr-1's dispay will turn red. The level you require will depend on the space you're in and its purpose. If you're in a studio you should be in the green/amber range. A club or venue will almost always exceed 85dB(A).

  • <80

    Unlimited safe listening time

  • 83

    Optimum level for mixing and mastering.

  • 85

    Threshold for hearing damage. (13hrs/week max)

  • 90

    Loud, likely to cause hearing damage

  • 100

    An approximate target level for a club sound system.

5. Placement

The Ohr-1 is versatile and can be placed in a variety of locations. As a general rule of thumb try not to place the device directly in front of monitoring speakers (if in a studio). The Ohr-1 works well placed on your mixing desk in front of you, adjacent to monitoring speakers or on top of monitoring speakers.

6. Device Care

We have built the Ohr-1 to be rugged and durable, however we recommend the following care:

  • Avoid liquid exposure.
  • Avoid getting dirt and liquid into the microphone port (located on the top of the device).
  • While the Ohr-1 can take a beating we recommend wrapping the Ohr-1 in something soft to avoid any light cosmetic damage when placed in a bag.

We are firm believers in right to repair. The Ohr-1 has been designed in a modular way that allows easy repair and replacement of components. We stock and sell all the necessary replacement parts for the Ohr-1, just get in touch!

7. Tech Specs

  • The Ohr-1 measures A frequency-weighted, slow time-weighted SPL
  • Frequency Response: 20Hz–12,500Hz
  • SPL Range: 32dB(A)–128dB(A)
  • Accuracy: tested with a class II SLM calibrator. Accurate to ±1dB(A) at 1000Hz. Uncertainty may be higher across the frequency spectrum
