HR-2; and so on. There is no limit to the number of HR-2's that may be chained together. However, if low impedance headphones are used, twelve is the recommended maximum. One or two sets of studio speakers may be connected to the HA-6A. If two sets are needed, the "B" pair must be connected to the XLR output. HR-2 Remote Stations cannot be used in this case. Rehearsal Headphones are used in rehearsal sessions not only to avoid disturbing neighbors with loud sounds, but also to provide each musician an easily controlled mix of all the other tracks. Using headphones guarantees that each will hear a balanced mix regardless of where they are positioned relative to various instruments or speakers-a luxury not always available in performance. As in recording, a mixing board must be used, whose output will drive the HA-6A either in mono (use Left Input only) or stereo (use both inputs). The main consideration in locating the HA-6A is whether each musician will need easy access to his or her own volume control. If the musicians are spread around a large room, the use of a chain of HR-2 Remote Stations may be more convenient than having each pair of headphones plug directly into the HA-6A. Language Labs Language labs occasionally need to drive as many as 50 headphone sets. If more than twelve sets are required, they should be high-impedance types. HR-2 Remote Stations provide a convenient way to place a volume control at each listening position (two listeners can share each box).
Use of the HR-2 Remote Stations (Satellites)
The HR-2 Remote Stations may be used to increase the number of headphones which can be accommodated by an HA-6A, and to place a volume control within easy reach of each individual needing it. They are compact boxes which easily attach with a thumbscrew to any microphone stand. Each HR-2 has two stereo volume controls and two headphone jacks. There are also two XLR connectors, one male and one female. These may be used to "daisy chain" HR-2 boxes together with -standard microphone cables. Begin the chain at the SPEAKER B - SATELLITE/R EMOTE connector on the rear of the HA-6A. The HA-6A connects to the first HR-2 box; another mic cable connects the first HR-2 box to the second HR-2 box; a third mic cable connects the second HR-2 to the third HR-2; and so on. If low impedance headphones are used, up to twelve HR-2's may be in the chain. If medium or high impedance headphones are used, 25 or more Remote Stations may be chained. If desired, the clip on an HR-2 box may be hung on a belt if no microphone stand is convenient.
