Safety Information
Connection Warning
DO NOT CONNECT OCTO MIXERS TO A PRO HUB, OR PRO MIXERS TO AN OCTO HUB. Damage to either system can occur!
English
Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably to noise induced hearing loss but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient time.
The U.S. Government's Occupational Safety and Health Administration (OSHA) has specified the following permissible noise level exposures:
| DURATION PER DAY (HOURS) | 8 | 6 | 4 | 3 | 2 | 1 |
| SOUND LEVEL (dB) | 90 | 93 | 95 | 97 | 100 | 103 |
According to OSHA, any exposure in the above permissible limits could result in some hearing loss. Ear plugs or protectors in the ear canal or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss. If exposure in excess of the limits as put forth above, to insure against potentially harmful exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels, such as this amplification system, be protected by hearing protectors while this unit is in operation.

Important Safety Instructions
- Read all safety and operating instructions before using this product.
- All safety and operating instructions should be kept for future reference.
- Read and understand all warnings listed on the operating instructions.
- Follow all operating instructions to operate this product.
- This product should not be used near water, i.e. bathtub, sink, swimming pool, wet basement, etc.
- Only use dry cloth to clean this product.
- Do not block any ventilation openings. It should not be placed flat against a wall or placed in a built-in enclosure that will impeded the flow of cooling air.
- Do not install this product near any heat sources; such as, radiators, heat registers, stove or other apparatus (including heat producing amplifiers) that produce heat.
- Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
- Protect the power cord being walked on or pinched, particularly at plugs, convenience receptacles and the point where they exit from the apparatus. Do not break the ground pin of the power supply cord.
- Only use attachments specified by the manufacturer.
- Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer or sold with the apparatus. When a cart is used, use caution when moving cart/apparatus combination to avoid injury from tip-over.
- Unplug this apparatus during lightning storms or when unused for long periods of time.
- Care should be taken so that objects do not fall and liquids are not spilled into the unit through the ventilation ports or any other openings.
- Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way; such as, power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.
- The apparatus shall be connected to a mains socket outlet with a protective earthing connection.
- Mains plug is used as the disconnect device. It shall remain readily operable and should not be obstructed during intended use.
To prevent injury, this apparatus must be securely attached to a rack in accordance with the installation instructions.
- Detailed installation instruction in user manual.
Electromagnetic Compatibility
This device complies with part 15 of the FCC Rules and the Product Specifications noted on the Declaration of Conformity. Operation is subject to the following two conditions:
- this device may not cause harmful interference, and
- this device must accept any interference received, including interference that may cause undesired operation.
Operation of this unit within significant electromagnetic fields should be avoided.
- use only shielded interconnecting cables.
The Hub unit produces heat while powered, and therefore requires adequate ventilation to ensure the internal temperature stays within maximum operating temperatures (0° C to 54.5° C, or 32° F to 130° F).
Please ensure that these clearances are met:
- 0.85 inches of clearance on either side of Hub
- 1 inch of clearance in front of Hub
- 11 inches of clearance in back of Hub
Care should be taken so that the Mixer's ventilation holes remain unblocked, allowing adequate airflow through both sides of the unit.
If you want to dispose this product, do not mix it with general household waste. There is a separate collection system for used electronic products in accordance with legislation that requires proper treatment, recovery and recycling.
Private household in the 25 member states of the EU, in Switzerland and Norway may return their used electronic products free of charge to designated collection facilities or to a retailer (if you purchase a similar new one).
For countries not mentioned above, please contact your local authorities for a correct method of disposal.
By doing so, you will ensure that your disposed product under goes the necessary treatment, recovery and recycling and thus prevent potential negative effects on the environment and human health.

FCC Statement
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a commercial installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
