⑤ INPUTS: LINE 1 to 4 (RCA)
The LINE 1 to 4 inputs are for connecting "line level"
sources to your amplifier. It is designed to receive an
"analog" signal (as opposed to "digital" signal). To connect
your source we are using a traditional "RCA" cable, they are
usually identified by a color code "RED" to the RIGHT and
"WHITE" to the LEFT channel.
Connecting a turntable:
Most turntables have a "RCA"
output but the signal is not compatible with the "line
inputs" amplifiers.
.
To use a turntable, it is necessary to use a "phono preamp"
compatible with "cell phono reader" used. There are two
families of cells; MM (Moving Magnet) or MC (Moving Coil).
The majority of the public is using MM cells format.
OPTION (RCA)
.
Without Optional card, this input works as a 5
th
LINE input.
If you use an Optional Card, this RCA input will be disabled
in favor, for example, of the optional Bluetooth card
allowing you to listen to your music from your Smartphone.
In that case, when you are selecting the Option’s source
button (in front panel), you can listen to music from your
Bluetooth device.
SWITCH ANTI-HUM (GROUND ON / OFF)
.
Located under the amplifier at the back.
.
Your amplifier EX322.1 has a mains socket
outlet with a ground connection. The use of
this type of connection is recommended for
electrical
safety
reasons
(including
wetlands). However sometimes this connection "mass" is
the origin of "hum" audible from the speakers in a hi-fi
system to solve this problem, the cancellation of the ground
connection is sometimes sufficient.
.
To do this you have, under the amplifier, a switch to choose
to connect or not the mass of the device to the mains.
① PHONE / HEADPHONES
Important note:
Make sure the volume control is turned
down before connecting or disconnecting headphones.
Listening at high levels can cause permanent hearing
damage.
This taken Jack size 6.35 mm allows connection of stereo
headphones. It is advisable to use a listener with an
impedance between 32 and 600 ohm headphones. When
the headset is connected, the output to the speakers are
then cut.
② DIRECT
If this function is activated (light signal active), then the
BASS and TREBLE functions are disabled. The purpose of
this function is to shut down the electronic circuit’s tone
control and balance in order to best preserve the purity of
the music signal.
③ BASS and TREBLE
The button "BASS" setting can act on the relative level of
low frequencies to alter the tonal balance of the sound to
suit your room acoustics and your tastes. The "TREBLE"
button for meanwhile high frequencies.
.
When these buttons are in the middle position, it means
that the tonal balance is not changed. The adjustable range
is ± 10 dB.
+10 decibels knob turned in the direction of clockwise and
- 10 decibels knob turned anticlockwise.
Tone Controls:
These functions only affects music signals
output from the speaker outputs and the LINE OUT (RCA).
They are not active on the REC output (for recording the
original signals).
④ VOLUME
This knob adjusts the output volume of the amplifier at the
speaker outputs.
