FCC Statements

Caution: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 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 off 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 receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.

Danger
Exposure to extremely high noise levels may cause 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 to the above permissible limits could result in some hearing loss. Earplugs or protectors in the ear canal or over the ears must be worn when operating this amplification system in order to prevent permanent hearing loss. If exposure is in excess of the limits as put forth above, to ensure against potentially harmful exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of inducing high sound pressure levels, such as this amplification system, be protected by hearing protectors while this unit is in operation.

PA50 Control Panel

OVERVIEW: CONTROLS & FUNCTIONS BACK PANEL:

INPUT SECTION:
This is where you may plug in microphones, instruments, keyboards, drum machines, and other audio devices, adjust the volume, bass, and treble.

Mic Inputs: These XLR inputs are designed for low-impedance microphones or equipment that has a mic-level, balanced output (often called a Direct Out). Note: These inputs receive 15-volt phantom power. This is used to provide power to condenser microphones. Phantom power will not damage any dynamic or non-condenser microphone.
LINE Inputs: These ¼-inch inputs may be used to connect high-impedance microphones, keyboards, drum machines, and other audio devices.
AUX IN: Use this stereo input to connect an external audio device such as an MP3, CD player, or computer for playback. Note: Right and Left channels are summed to mono on this input.
Volume: Use these controls to adjust the volume level of each channel and the relative balance between them.
Low: Determines the emphasis of bass frequencies. Turning this knob clockwise creates a deeper, warmer tone. If you need a brighter sound, reduce the bass by turning counterclockwise.
High: Turned clockwise, this control accents treble frequencies to produce clearer, crisper sound. Turn counterclockwise to make the sound softer and less bright.
Master Volume: Controls the overall volume of all channels and input of the SYNC circuit. Note: Does not affect SYNC circuit Output level.
SYNC IN: This balanced XLR Jack accepts the SYNC output from another PA50 using a standard microphone cable. Channels from both PA50’s are summed together. Use the channel volume controls to get the mix of the 6 channels (If a channel is not used turn the volume all the way down). MASTER volume controls the loudness of the mix through its PA50. It does not affect the volume of linked PA50. Note: The shield connection (pin 1) on this jack is connected to the chassis ground. It is not lifted.
SYNC OUT: This balanced XLR Jack accepts the SYNC input from another PA50 using a standard microphone cable. Channels from both PA50’s are summed together. Use the channel volume controls to get the mix of the 6 channels (If a channel is not used turn the volume all the way down). MASTER volume controls the loudness of the mix through its PA50. It does not affect the volume of linked PA50. This jack may also be used to connect the PA50 to a power amp with a balanced line input.
Note: The shield connection (pin 1) on this jack does not connect to the chassis ground. It is lifted.
Subwoofer Out: The PA50 subwoofer output jack sends a line-level unbalanced low-frequency signal crossed over at 150Hz to a PA112S powered subwoofer. It will also work with any powered subwoofer that accepts line-level input. A crossover that rolls off the frequencies below 150Hz through the PA50’s speakers is activated when using this jack with a standard ¼” mono (tip/Sleeve) SHIELDED instrument cable. When Subwoofer jack is not used, this crossover is bypassed and PA50 speakers are full range. Note: It is recommended to connect the subwoofer using a standard ¼” mono (tip/sleeve) SHIELDED instrument cable because the sleeve connection to the ground activates crossover on PA50 speakers. When possible, plug AC cable on PA50 and Subwoofer into the same outlet or power strip. This will prevent possible ground loop hum through the system.
Power: This switch activates AC power to the powered PA.
AC Power Cord Receptacle: Insert the PA50’s AC cord ﬁrmly into the AC receptacle. Be sure to use the cable provided with your PA50. The power cord can be removed for storage or replacement if damaged. Note: Replace the AC cord if its protective jacket is damaged or the ground pin is damaged or removed.
