Can I buy one of the original Hear Back systems?

Our original Hear Back system is no longer in production. However, we’ve designed its replacement, the Hear Back OCTO, to outperform the original system while also being backward/forward-compatible with the original.

Are the original Hear Back system and the Hear Back OCTO system compatible?

Yes, the original Hear Back system and the Hear Back OCTO system are 100% forward and reverse compatible. You can mix and match Hubs and Mixers as needed.

Can I use off-the-shelf network switches for the original Hear Back or the Hear Back OCTO?

No. The Hear Back systems have their own protocol. You have to use a Hear Back original or OCTO Hub with Hear Back original or OCTO mixers.

Can daisy-chain mixers together?

No. None of our systems’ mixers can be daisy-chained (connected in a linear series). Mixers must have a home-run to a Hub.

How far can I run a cable from a hub to my mixers?

1. For the original Hear Back and the OCTO system, we recommend a maximum limit of 200 feet (61 meters). 2. The Hear Back PRO can handle a maximum run of 500 feet (152 meters).
These are both assuming you’re using quality cables. If the runs are any longer, you start losing quality.

Can I use Cat6 cables?

Yes, you can use either Cat 5e or Cat 6 cables with any of our systems.

Can I use any brand of cables?

Technically, yes. However, we strongly recommend using cable brands with well-established quality, such as West Penn, Belden, Carol, etc. If you use off-brand/overseas cables, you’re more likely to experience a loss of sound quality.

What punch-down (pin-out) standard should I use with RJ45 connectors?

You can use either A or B pin-outs, but with NO CROSSOVER. You’ll need the same pin-out on both ends of your cable. We recommend using standard B with, again, no crossover. Crossover will damage components within the system. Also, do not use standard flat, gray telephone cable – it won’t work.

Can I run my system through my building’s network switch?

No. It won’t work and it might damage components in the system. Hear Back systems should be stand-alone.

I have an original Hear Back or Hear Back OCTO system. Why is my Channel 2 knob dead? Help!

You’ve linked channels 1 and 2 by pressing the center capacitive-touch button (on an OCTO) or link button (on the original). Both systems have a button designed to link the first and second channels, allowing channels 1 and 2 to serve as hard left and right pans.
To separate them out into two channels, simply press the center “link” button between them again.

How many headphones can I use on each mixer?

On all our Hear Back systems, each mixer can comfortably handle two sets of headphones. If you connect any more than two headsets, the mixer will start losing power to the headphones.

Can we use our original Hear Back system with the Hear Back PRO?

Nope. The Hear Back PRO mixers are not compatible with original Hear Back hubs, nor vice versa. You can mix-and-match between the original Hear Back and the Hear Back OCTO, but the PRO has its own protocol.
There is one exception: If you purchase our available ADAT card and install it in a PRO Hub, it provides two original Hear Back Hear Bus outputs and can route the PRO Hub to the Original hub. From there, you can control the Original Hear Back mixers that way.

Do the original Hear Back or the Hear Back OCTO support SMUX (S/MUX)?

No. Our system does not support SMUX (S/MUX). If you try, you’ll end up with pops and crackles.

What’s up with the AUX input on my original Hear Back or Hear Back OCTO mixer?

The AUX input is controlled by the mixer’s master knob only. Aside from that knob, the level must be set from the console or other device providing the feed.
