The unit provides 2 rotary controls and 2 stereo jacks per channel. (4) INPUT SIGNAL SOURCE SELECT SWITCHES Each channel features a rotary selector switch which allows you to select any of the 4 stereo input source signals connected to the INPUTS (3) of the H4 to be routed to the selected chan- nels of the headphone amplifier and line distribution output. Sim- ply choose the source signal desired for that channel. (5) VOLUME CONTROLS Each channel features a rotary volume pot for variable adjust- ment of the desired output level. (6) POWER LED INDICATOR This LED indicator illuminates when the unit is powered on by the rear panel POWER SWITCH (7). REAR PANEL (3) AUDIO INPUTS Four stereo-pair line level 1/4” TS jacks for 4 stereo (L & R) input signals. If only the LEFT (MONO) channel input is used, the mono signal will be provided automatically at both the Left and Right sides of the PHONE (1) and LINE (2) outputs. (8) POWER CONNECTOR WITH FUSE HOLDER Standard IEC power cord receptacle used to connect the AC power to your unit. It features a built-in fuse holder for a 5X20mm, 0.5A/250V slow-blow fuse. If the fuse continuously blows, shut off the unit and have it serviced by qualified service personnel. REAR PANEL (7) POWER SWITCH To turn the unit ON or OFF, press the upper or lower portion of this button as indicated. The front panel POWER LED INDICA- TOR (6) will illuminate when the power is “ON”, Before turning on this unit, verify connection to the proper voltage AC source, check all connections and turn down the level controls of equipment connected to the outputs. (9) AC VOLTAGE SELECTOR SWITCH Before plugging in the power cord, check to see that the unit is set for the proper voltage for your area: ~115v (60Hz) or ~230V (50Hz). (Note: use at the improper voltage can damage your unit and void the warranty.) WARNING IMPORTANT SAFETY INSTRUCTIONS When using this electronic device, basic precautions should always be taken, including the following: 1. Read all instructions before using the product. 2. Do not use this product near water (e.g., near a bathtub, washbowl, kitchen sink, in a wet basement, or near a swimming pool, etc.). 3. This product should be used only with a cart or stand that will keep it level and stable and prevent wobbling. 4. This product, in combination with headphones or speakers, may be capable of producing sound levels that could cause permanent hearing loss. Do not operate for a long period of time at a high volume level or at a level that is uncomfortable. If you experience any hearing loss or ringing in the ears, you should consult an audiologist. 5. The product should be positioned so that proper ventilation is maintained. 6. The product should be located away from heat sources such as radiators, heat vents, or other devices (including amplifiers) that produce heat. 7. The product should be connected to a power supply only of the type described in the operating instructions or as marked on the product. Replace the fuse only with one of the specified type, size, and correct rating. 8. The power supply cord should: (1) be undamaged, (2) never share an outlet or extension cord with other devices so that the outlet’s or extension cord's power rating is exceeded, and (3) never be left plugged into the outlet when not being used for a long period of time. 9. Care should be taken so that objects do not fall into, and liquids are not spilled through, the enclosure’s openings. 10.

An equilateral triangle enclosing a lightening flash/arrowhead symbol is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product's enclosure which may be of sufficient magnitude to constitute a risk of electric shock. CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN An equilateral triangle enclosing an exclamation point is intended to alert the user to the presence of important operating and service instructions in the literature enclosed with this unit. DO NOT REMOVE COVER (OR BACK). NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING ATTENTION: RISQUE DE CHOC ELECTRIQUE NE PAS OUVRIR INSTALLATION To ensure years of enjoyment from your HA4X4, please read and understand this manual thoroughly before using the unit. INSPECTION Your HA4X4 was carefully packed at the factory in packaging designed to protect the units in shipment. Before installing and using your unit, carefully examine the packaging and all contents for any signs of physical damage that may have occurred in transit. (Note: Elite Core is not responsible for shipping damage. If the unit is damaged, do not return to us, but notify your dealer and the shipping company immediately to make a claim. Such claims must be made by the consignee in a timely manner.) RACK MOUNTING The HA4X4 fits into one standard 19” rack unit of space (1 3/4”). Parts of the unit can become very warm during use. This is normal during operation. Care should be taken to ensure that there is enough space around the unit for cooling (at least 12” or 30cm). Do not place the HA4X4 on high temperature devices such as power amplifiers, etc., or the unit may overheat in operation. Also, do not place the unit on speakers as this may cause them to move and/or fall due to speaker vibrations. Although the unit's chassis is shielded against radio frequency (RF) and electromagnetic interference (EMI), extremely high fields of RF and EMI should be avoided. POWER CONNECTION The HA4X4 has an internal power supply and is designed to operate from an external AC source. Power requirements for electrical equipment differ from area to area. Be sure to confirm that the voltage selected by the voltage selector switch on the back panel is proper for your area (120VAC/60Hz or 230VAC/50Hz) per the information below: Europe (except UK): 230V, 50Hz UK and Australia: 240V, 50Hz USA and Canda: 120V, 60Hz For other areas, please check with local authorities. When ready to operate, plug the AC cord into the power source. Make sure that the unit is turned off before connecting to the AC power source to avoid possible loud transients which can damage your speakers or your ears, especially when monitoring with headphones. APPLICATIONS USING THE HA4X4 AS A HEADPHONE AMPLIFIER e Connect a stereo (L 4 R) program source (2 x 1/4” plugs) to the rear of the HA4X4 using one of the available 4 x stereo INPUT (3) pairs on the rear panel. e Connect a set of headphones using a stereo 1/4” cable to any of the HEADPHONE OUTPUTS (1) on the front panel of the HA4X4. e Select the source signal from the rotary SELECTOR (4) switch for the channel in use. Set to an appropriate level for monitoring. (Note: If only the LEFT (MONO) channel input is used, the mono signal will be provided automatically at both the Left and Right sides of the PHONE (1) and LINE (2) outputs.) Since the HA4X4 offers four independent channels, you can have four individual mixes for four musicians with a single unit. In studio recording applications, you can configure sub-groups, aux sends or single outputs of your audio mixer to feed signals independently to the HA4X4. This enables each musician to receive a specific configuration of instruments of their choice in their headphones. (Note: If four headphone outputs are not enough, you can interface and link any number of HA4X4’s for additional outputs [see below]) USING THE HA4X4 AS A LINE DISTRIBUTION UNIT To use the HA4X4 as a line distribution unit all you have to do is use the line output instead of the headphone output on the front of the unit for the line distribution signal feed. All other operation is identical as using the unit as a headphone amplifier. Daisy chaining mulitple HA4X4’s together for additional headphonelline distribution requirements: It is very easy to chain multiple HA4X4’s together. use appropriate single stereo 1/4” TRS to two 1/4” TS (2 x mono) adapter cables and make connections from the LINE DISTRIBUTION OUTPUT (2) channels on the front of your first HA4X4 unit to the stereo (L&R) AUDIO INPUTS (3) on the rear of the second HA4X4. This effectively allows an additional (fully selectable) 4 headphone outputs and an additional 4 line outputs. You can continue to chain up to four HA4X4 units together using this same procedure. ">
