Female XLR Input The female XLR input can be used for either the connection of a microphone or a line level audio signal. This input can be used at the same time as the 3.5 mm line input. 2. Mic / Line Selector Switch The Mic / Line Selector Switch determines whether the female XLR is to be used as a mic level or line level input. 3. 3.5 mm Line Input The 3.5 mm input is a mono, line level input. This input can be used at the same time as the XLR input. 4. Male XLR - Output / Com Link The Male XLR output can be used in two ways. As a balanced, fixed level output or as a telecom link for your beltpack intercom system. 5. 1/4” Headphone Jack The headphone output is a 1/4” 3 conductor jack. Both the tip and ring of this jack contain the same audio signal. Either mono or stereo headphones may be used. 6. Female XLR Input Level Control The Mic Input volume control adjusts the level of audio from the female XLR input. Adjustment of this control determines the level of audio you send down the phone line from this input.* 7. 3.5 mm line input level control The Line Input volume control adjusts the level of audio from the 3.5 mm input. Adjustment of this control determines the level of audio you send down the phone line from this input.* *The FCC requires that a limiter be present in any device that connects to a phone line. The peak limiter within the Compack will help to control the audio level sent down the phone line so it does not exceed the maximum audio level specified by the FCC. 8. Headphone Level Control The headphone volume control adjusts the level of audio sent out the 1/4” headphone jack. Adjustment of this control will determine the level of audio you hear in your headphones. 4 Features 9. Battery Test Button / LED To test the battery, simply press the Battery Test button on the side of the unit. If the LED lights, the battery is still good. The unit may still function if the LED does not light, but there will be significant audio distortion and a loss of level as the battery continues to discharge. Under normal use you should get at least 20 hours of continuous use from one fresh 9 volt alkaline battery. 10. Power Switch The power switch should be left in the off position any time the unit is not being used or battery drain will occur. The unit will retain a phone line connection if the power switch is turned off during a call. 11. Phone Line Switch This switch acts as the switch-hook for the telephone line. The Hang Up position is the normal on-hook position when you are not using the line or you are waiting for a call. When you want to place a call, or when a call comes in, switch to the Dial/Talk position. When using the Handset or Wireless Interface, the switch should remain in the Hang Up position at all times. 12. Phone Line Jack Use this jack to connect to standard analog telephone lines or a fax / modem adapter for analog cell phones. A 60” RJ-11 cable is provided with the unit. This jack should not be connected directly to digital PBX or ISDN phone systems. 13. Visual Ring Indicator The Ring LED will flash when there is an incoming call from the phone line. This feature is disabled when ComPack is being used with the handset interface or the wireless phone interface. 14. DTMF Keypad The telephone keypad is equipped for tone dialing only. You may use the keypad at anytime during a call but keep in mind that transmit audio is muted during a keypress. This keypad should only be used to dial calls when the unit is connected directly to an analog telephone line. 15. Keypad On / Off Switch This switch disables the DTMF keypad to prevent tones from being blasted down the phone line during a broadcast. You should leave this switch in the off position when using the wireless phone or PBX handset interface. 5 Features 16. Wireless / Cellular Telephones ComPack comes equipped with a built in cellular telephone interface. This 1/4” wireless interface jack accepts a special 1/4” to 2.5 mm cable provided with the unit. This interface will work with any wireless phone that can accept third party headsets and earpiece headsets. Some wireless telephones have the standard 2.5 mm jack while others have proprietary jacks. Adapters to convert the proprietary jack to the standard 2.5 mm jack are available for most wireless telephones through local electronic stores or their respective telephone dealers. When using the wireless interface, it is important to keep your wireless telephone 12” - 24” away from the ComPack and any microphone or headphone cables. This will help prevent unwanted RF noise from entering the unit. The wireless interface on the ComPack works very well with most cellular telephones. However, some wireless telephones generate excessive RF noise which can be can be heard as a “chattering” or “motor boat” sound. The noise from these particular telephones will be unacceptable for most broadcast applications. 17. Handset Interface If you cannot get to an analog phone line or if the phone system is a digital or analog PBX, ISDN, or a key telephone system, You can use the built-in handset interface. Simply disconnect the handset from the coily cord and plug the cord into the PBX Handset Interface Jack. Dialing must be done with the existing telephone. Make sure to leave the telephone handset off hook or disconnection will result. 18. Handset Type Selector Switch You will need to select the handset microphone type of the telephone that ComPack is connected to when using the PBX handset interface. Trial and error works faster than a chart of handset types, but this basic description may help. Switch Position A B C Handset Microphone Type Electret Dynamic Carbon 6 Features 19. Battery Door The easy change battery door can be opened by inserting a small object into the slot, such as a coin or fingernail, and lifting up and out. The battery should be removed if ComPack is not going to be used for extended periods of time. 20. 9 VDC Power Jack ComPack is powered by either one 9 volt battery or the included AC adapter. The provided AC to DC adapter is a high quality, regulated power supply. When the power supply is connected to ComPack, battery power is bypassed. This AC adapter is for powering the unit only, it does NOT charge the battery. *Make sure to use only the supplied AC adapter with ComPack. Using any other adapter can cause poor audio quality and/or damage the unit. If you need an additional AC adapter, contact the distributor you purchased ComPack from and ask for a JK Audio 9 volt power supply, JK Audio part # PS004. ComPack General Operation 1.
