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 disturbin g neighbors with loud sounds, but also to provide each
musician an easily con trolled 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 re cording, 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 lis tening 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 head phones which can be accommodated by an HA -6A,
and to place a volume con trol 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.
