Improper installaons of this type create the possibility of re 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 suscepbility to noise- induced 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 potenally 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 operaon. Ear plugs or protectors in the ear canals or over the ears must be worn when operang the equipment in order to prevent permanent hearing loss if exposure is in excess of the limits set forth here. Keep your's aenon that children and pets are more suscepble to excessive noise levels.

The HPAMP106 is a 6-channel Headphone Amplier boxed in a 19” rack mountable metal chassis, including up to 6 independent high-power amplier secons suitable for virtually any type of headphones, HPAMP106 features 4 selectable main stereo/mono inputs with ¼” JACK connectors (REAR panel). The signal is amplied 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 = posive LEFT channel signal Ring = posive RIGHT channel signal Sleeve = common negave 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 respecve headphones output. In the OFF posion no input is selected.

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 = + posive or "hot" Ring = - negave or "cold" Sleeve = shield or ground When connecng an unbalanced signal, wire them as follows: Pin2 / Tip = + posive 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 seng is for mains line in the range of 100-120V~ and 230V seng is for mains line in the range of 210-240V~.

WARNING: an incorrect seng of AC LINE VOLTAGE could damage seriously the internal electronics!

HPAMP106 is "ON" when the switch is in the "I" posion.

Here is where the mains protecon 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
