less prominent. lt also helps adjust to deficiencies in your
loudspeakers or listening environment.
Further flexibility is provided by the Turnover buttons. These
alter the frequencies which the bass and treble controls affect.
The outer position of each selects control over freouencies
closer to the midrange where your ears are more sensitive;
making the effects of the bass and treble controls more
noticeable. The inner position selects more extreme freouencies
where your ears are less sensitive and the effect is more subtle.
The Loudness button activates a circuit that slightly boosts
extreme bass and treble frequencies. Because your ears are less
sensitive to these extremes at low volumes, this circuit
compensates so that you hear all the music. Avoid excessive
bass control boost when the Loudness button is oushed.
The Hi Filter reduces the high frequency content of the sound.
It will reduce "hiss" in tapes and broadcasts. Use only as
needed.
The Balance control adjusts relative volurhe between the Right
and Left channels. Use it if you sit closer to one speaker than the
other so that the sound source is "centered't.
H ead phones
This is the output for stereo headphones. Plug in your
headphones for private listening; you can elect to have speakers
on also if you wish. However, unplug headphones when you
aren't using them; high power surges could damage them.
Overload Indicator
The Reference:650FETR
has a small red LED located next lo
the power button. lt lights to indicate a short-circuit or overload
condition and the sound shuts off. This protects critical circuit
components from damage. lf the LED lights, turn off the power
and check all your speaker connections. Normal operation may
be resumed by waiting 15 seconds before.turning power on again.
Power Meters
The Reference:650FETR
has two unique 9-position LED power
indicators. They enable you to relate the power function of the
amplifier sections lo your desired listening level. The last section
of these indicators marked Clipping will flash when the amplifier
approaches its maximum undistorted capacity. lf the last LED's
stay lit you are operating at or beyond the timits of the 650FETR.
This could cause sustained speaker damage from overload.
