THE INPUT STAGE
The 'front end' is an entirely new design using 5 complete stages
of amplification controlled by a single volume control. The design gives
(microphone) input headroom of more than 30dB; the input is floating balanced
and will easily accept microphone levels from -70dB up to more than 0dB.
Phantom power is provided for capacitor microphones. Noise performance
is up to finest laboratory standards (-125.5dB below input 20Hz to 20kHz
200 Ohm input termination). The line input is designed for balanced circuits
and will accept -30dB up to +24dB. The nominal operating level at the
'insert' point is -10dB but as maximum output at that point is +24dB the
Pro Channel can operate with any mixer.
THE COMPRESSOR
The built-in JOEMEEK compressor is slightly different from the big
studio unit so it is easier to use with musical instruments. The attack
is variable between 1ms and 11ms. The release is variable from 125mS up
to 1.5 seconds. There is an in/out switch for comparisons. The compression
control is rotary. The compression ratio varies from 1.5 to 1; up to 7
to 1; depending on musical content and it's auto ratio makes it easy for
the user to operate.
THE EQ
The equalizer can change the sound of an instrument or voice by altering
the high, mid or low frequencies separately, but at the same time, making
those changes musically. The controls not only add or subtract volume
in the three frequency bands called 'treble', 'mid' and 'bass', but also
alter the phase relationships of these frequency bands. This is a major
factor in the 'musicality' of the equalizer. Unlike other equalizers,
the actual frequencies are not specified. The reason for this is that
in order to sound completely musical, there is considerable overlap between
the sections so that '8KHz' actually has a great effect at both 20KHz
and at 2KHz; if it didn't, it would sound bad. This is why our EQ has
the classic warmth and tone of the old world class Neve EQ's. The EQ is
defeatable for direct comparrisions of wet and dry.
TREBLE CONTROL
Approx 18dB lift and cut at the shelving frequency of 8KHz. (fixed)
MID CONTROLS
Approx 16dB lift and cut at 1.8Khz (fixed)
BASS CONTROL
Approx 18dB lift and cut at the shelving frequency of 80Hz. (fixed).
THE METER
The first green LED of the meter array stays on all the time to show
that the power is on. The second green LED lights at an output level of
-12dB. The second yellow LED lights at an output level of -6dB. The orange
LED lights at an output level of 0dB. The red LED lights at an output
level of +8dB. An overload meter is located after the EQ, so the user
will be sure if any large amounts of gain are added.
OVERALL PERFORMANCE
Frequency response +0 -0.5dB 10Hz to 50KHz Low frequency accuracy
maintained to get clear unmuddled bass sounds onto digital recorders.
Harmonic distortion less then 0.01% except where compression effects low
frequency wave shape. Noise generally 100dB below input (125.5dB below
input on mic at more than 50dB gain)
THE OUTPUT STAGE
An LED 'meter' shows levels immediately before the output stage.
An output volume control gives the choice of output volume levels. Two
output jack sockets are identical with each other but buffered from each
other. Output is balanced 600 ohm with maximum output +24dB. Noise approx
-80 dB.
TECHNICAL NOTES
Adds warmth power and 'thickness' to modern digital studio sound.
The JOEMEEK Pro Channel offers the absolute pinnacle in professional audio
sound and quality.
The ultimate dynamic effects processor for bass players guitarists and
vocalists in live and recording applications.
An ultra high quality microphone pre amplifier.
'Power-up' and smooth out samples before committing them to tape or hard
disk.
