–Power supply cord should be unplugged from the outlet during strong thunderstorm or when left unused for a long period of time.
–Do not place objects on the product’s power cord or place it in a position where anyone could trip over, walk on or roll anything over it. Do not allow the product to rest on or to be installed over power cords of any type. Improper installations of this type create the possibility of fire hazard and/or personal injury..
–This product may be capable of producing sound levels that could cause
permanent hearing loss.. Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably in susceptibility to noiseinduced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently 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.. Keep your's attention that children and pets are more susceptible to excessive noise levels..

GENERAL INFORMATION
Thank you for having chosen a PROEL product..
The HPAMP106 is a 6-channel Headphone Amplifier boxed in a 19” rack mountable metal chassis, including up to 6 independent high-power amplifier sections suitable for virtually any type of headphones,
HPAMP106 features 4 selectable main stereo/mono inputs with ¼” JACK connectors (REAR panel).. The signal is amplified and sent to 6 stereo headphone outputs with individual level controls, input selector and ¼” JACK connectors
(FRONT panel), each one with +13dB max output level (per channel).. Each output is capable of driving 16 ohm output load impedance.. HPAMP106 is powered by a Built-in power supply with shielded transformer and voltage selector..
OPERATING INSTRUCTIONS (FIG. 1 / 2)
1. HEADPHONES stereo jack outputs
These are the 6 STEREO JACK connectors for the headphones output: only stereo headphones with a minimum impedance of 16 Ohms should be connected to these outputs.. The stereo jack connectors are wired as follow:
Tip = positive LEFT channel signal Ring = positive RIGHT channel signal
Sleeve = common negative shield or ground for both channels
2. VOL headphones volume controls
These controls set individually the level of each HEADPHONES output.. The signal of the 6 outputs is selected between the four inputs..
3. INPUT SEL input channel selectors
Using these selectors you can choose which one of the 4 available inputs is sent to the respective headphones output. In the OFF position no input is selected.
4. PWR indicator
BLUE LED: when lighted indicates that the HPAMP106 has been turned on and AC power is available..
5. INPUT - LEFT (MONO) jack
These are the 4 JACK connectors for the four stereo channel inputs.. Each LEFT (MONO) is a female jack connector, which accepts a JACK plug from almost any line level equipment with a balanced or unbalanced outputs.. If the correspondent RIGHT jack is not inserted, the channel operate like a MONO channel with the LEFT (MONO) input as a single signal source.. The JACK input is wired as follows:
Tip = + positive or "hot" Ring = - negative or "cold"
Sleeve = shield or ground
When connecting an unbalanced signal, wire them as follows:
Pin2 / Tip = + positive or "hot"
Pin 1-3 / Sleeve = shield or ground
NOTE: whenever possible, use always balanced cables. Unbalanced lines may also be used but may result in noise over long cable runs. In any case, avoid using a balanced cable for one channel and an unbalanced one for the other.
6. INPUT - RIGHT jack
This is a JACK connector, which accepts a balanced or unbalanced line level input signal from almost any source.. This is used only in presence of LEFT jack input to use the channel as STEREO.. Wiring is the same of previous point..
7. LINE VOLTAGE selector
This switch sets the AC voltage line of your country (usually it is set by factory and isn't necessary to change it).. The 115V setting is for mains line in the range of 100 120V~ and 230V setting is for mains line in the range of 210 240V~.
WARNING: an incorrect setting of AC LINE VOLTAGE could damage seriously the internal electronics!
8. POWER switch
HPAMP106 is "ON" when the switch is in the "I" position.
9. FUSE holder
Here is where the mains protection fuse is placed.
REPLACE THE PROTECTION FUSE ONLY WITH SAME TYPE AS SHOWN ON THE PRODUCT.
IF AFTER THE SUBSTITUTION, THE FUSE INTERRUPTS AGAIN THE APPARATUS WORKING, DO NOT TRY AGAIN
THEN CONTACT THE PROEL SERVICE CENTER.

10. AC~ socket
Here’s where you plug in the mains supply cord.. You should always use the mains cord supplied with the HDAMP106..
Be sure the unit is turned off before you plug in the cord.
