2. NOTE:

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 5 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential 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.If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment o and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

• Connect the equipment into an outlet on a circuit dierent from that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

CAUTION: Changes or modiﬁcations to this device not expressly approved by

LOUD Audio, LLC could void the user’s authority to operate the equipment under FCC rules.

22.

This apparatus does not exceed the Class A/Class B (whichever is

applicable) limits for radio noise emissions from digital apparatus as set out in the radio interference regulations of the Canadian Department of Communications.

ATTENTION

— Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant las limites applicables aux appareils numériques de class A/de class B (selon le cas) prescrites dans le réglement sur le brouillage radioélectrique édicté par les ministere des communications du Canada.

23.

Exposure to extremely high noise levels may cause permanent hearing loss.

Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to suciently intense noise for a period of time. The U.S. Government’s Occupational Safety and Health Administration (OSHA) has speciﬁed the permissible noise level exposures shown in the following chart.

According to OSHA, any exposure in excess of these permissible limits

could result in some hearing loss. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels use hearing protectors while the equipment is in operation. Ear plugs or protectors in the ear canals or over the ears must be worn when operating the equipment in order to prevent permanent hearing loss if exposure is in excess of the limits set forth here:

CAUTION

RISK OF ELECTRIC SHOCK! DO NOT OPEN!

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK DO NOT

REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE.

REFER SERVICING TO QUALIFIED PERSONNEL.

The lightning ﬂash with arrowhead symbol within an equilateral triangle is intended to alert the user to the prescence of uninsulated “dangerous voltage” within the product’s enclosure, that may be of signiﬁcant magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to alert the user of the prescence of important operating and maintaining (servicing) instructions in the literature accompanying the appliance.

WARNING — To reduce the risk of ﬁre or electric shock, do not expose this apparatus to rain or moisture.

REVISION

Let’s take a look at a typical hookup diagram for the HM-400, starting with the front panel connections. There

are four channels, so connect a pair of stereo headphones to each headphone out jack. Next, connect cables between the mixer’s aux out jacks to each HM-400’s 1/4" aux input jacks. There is also a 1/4" main input jack on the far lef of the HM-400. Feel free to feed a computer or other audio source into this input.

Now let’s look at the rear panel from lef to right. There are eight 1/4" headphone jacks, two for each channel.

Connect as many stereo headphones as necessary to these jacks. Next up are the main output L/R jacks. These outputs may be connected to the main inputs of an additional HM-400 or to speakers in a live room. On the far right are the main input jacks. These are typically connected to the main outputs of a mixer, although a computer or other audio source also works. For convenience, both the main inputs and outputs of the HM-400 contain XLR and 1/4" jacks. You can choose between the XLR or 1/4" inputs, but not both simultaneously. We appreciate your ability to multi-task, but it’s getting out of hand!

Once the connections are made and the music playing, set the input and output levels as desired, along with

EQ settings, balance and/or main / aux level, stereo / 2-channel switch position, etc.

8–CHANNEL HEADPHONE AMPLIFIER

POWER

OUTPUT

The front panel of the HM-800 has eight headphone output jacks, so connect a pair of stereo headphones

to each channel that will be utilized. Like the front panel, the rear panel of the HM-800 also has eight headphone output jacks, one for each channel. Again, connect as many headphones as needed to each jack.

Let’s look at the rest of the rear panel from lef to right. Above each headphone output jack is an aux input

jack. These are connected to each aux output jack of the mixer. To the right of the headphone out and aux in jacks are two pairs of 1/4" main output jacks and two pairs of 1/4" main input jacks.

Here we have L/R output 1 connected to a pair of studio monitors located in a live room, while L/R output 2 is

connected to the main inputs of an additional HM-800. The main input jacks are typically connected to the main outputs of a mixer (as seen in this illustration), but with an additional pair of input jacks available, we’re able to connect it to a computer or other audio source’s output jacks.

Once the connections are made and the music playing, set the input and output levels as desired, along with

your choice to hear source input 1 or 2 and listen in stereo or mono. Once an aux source is plugged in, though, it overrides BOTH main inputs and will be the only available source until the aux cable is removed.
