using the 'Superbal' electronic circuit designed by Ted Fletcher in the mid
70's. The circuit gives excellent rejection of electrical interference.
On the front of the unit there is an unbalanced 'instrument' input designed
with gain and impedance specifically for guitars or basses. Use of this
socket disables the rear inputs (both mic and line).
BALANCED AND UNBALANCED
The JOEMEEK Studio Channel is designed to be used in the best studios
where most (if not all) interconnections are 'balanced'. Balanced operation
means that the audio is carried on two wires working in opposite phase.
Then should any interference appear on the 'line' , it will be effectively
cancelled out.
Both of the main inputs (Microphone and Line) and the four main outputs
(two per channel) are balanced to get best advantage from true balanced
operation; but unbalanced operation (for line level signals) will NOT
degrade the performance due to a new type of balanced output stage.
OPERATING THE MICROPHONE AMPLIFIER
·
Press in the 'MIC/LINE' switch. (in for MIC and out for LINE).
·
Turn the INPUT GAIN knob down to minimum then, If you are using
a capacitor microphone, plug in the microphone, then switch on the
phantom power by pressing in the 'Phantom' switch. (Do it in that
order). NOTE.Some phantom powered microphones take several
minutes to reach correct working conditions. Remember to switch on
at least 5 minutes before using the microphone.
·
Turn up the INPUT GAIN until sound registers on the VU meter (VU
switch in). Do not let the VU needle hit the end stop too hard or
overload may possibly happen. The meter electronics has been
adjusted so that it is normal for the needle to move in the red area.
OVERLOAD MARGIN AND THE VU. METER
The 'TwinQ' is set up so that when the output gain control is set to '0' and
the meters are indicating '0', then the output is '0' dBu (0.775V rms).
Moving the output gain control to maximum will give an additional 4 to 6 dB
of level output, the meter reading will stay the same. This system; called
'input' metering, makes the 'TwinQ' very flexible for driving into different
types of mixer/recorder which may require different input levels.
