USInG THe RCA THRU-PUTS
The HA15 is equipped with a pair of RCA thru-puts that can be used to
feed a secondary device such as another HA15 or the TAPE or AUX input
on your receiver. This thru-put adds flexibility to your setup and will make it
easier to integrate the HA15 into your system.
You could for instance connect a CD player to the HA15 and then send
the output from the CD player (via the THRU) to your receiver. This would
enable you to turn off the receiver or hi-fi system for quiet listening without
having to re-patch.
Note that these are simple pass through connections. This means that the level or Focus
controls will have no effect on the signal.
THe FoCUS ConTRol
The Focus control is a very powerful feature that will enthrall as it brings
a greater sense of presence to your musical listening pleasure. It is
designed to simulate the effect of listening to music in a typical room using
loudspeakers. To understand the significance, one merely has to think
about how the music was recorded and how this differs from headphones.
In the studio, music is recorded using a combination of nearfield monitors
and larger playback monitors during the final mix and mastering.
Headphones are secondary. This means that when the engineer or
producer was placing instruments and voice across the sound-field, they
were actually making ‘mix decisions’ while listening to the recording as it
emanated from both loudspeakers at the same time. With headphones, the
sound going to each ear is completely isolated from the other. This results
in a ‘wider than recorded’ stereo field which is not natural. The intended mix
is lost and so is much of the ‘energy’.
