    Ted Fletcher This instruction book was written by Ted Fletcher; the designer of the original JOEMEEK compressor and the whole JOEMEEK range of professional audio equipment. Ted worked in the studio with Joe Meek, the legendary record producer, in the mid 1960s.

    Nowadays, many of these notions have been forgotten and 'quality' electronics is getting rarer and rarer. But the JOEMEEK range of Studio channels and the PROCHANNEL apply these professional rules and you can hear the difference! The function of a microphone preamplifier is not too difficult and the microphone/input amplifiers on normal professional mixers do it quite well;...
  • Page 5 As well as giving the best performance with keyboards, guitars and basses, the ProChannel is also designed to work well with the best capacitor microphones; it is particularly good with the JOEMEEK JM47, Neumann range, the AKG C414, Microtech Gefell, and Audio Technicas.

    Out Vol Phantom (80Hz) (1.8kHz) (8kHz) Input Gain It's best to think of the JOEMEEK VC3Q PRO CHANNEL as three separate pieces of equipment: 1) The Input amplifier. 2) The JOEMEEK Compressor. 3) The Meequalizer THE INPUT AMPLIFIER The input amplifier takes audio signals from any microphone (XLR socket), musical instrument or high level source (1/4 inch jack socket), and amplifies them up to 'line' level;...

    A secondary use of compression (and most important for us) is to introduce some artificial dynamics into sound to make it sound more exciting. This is what the JOEMEEK compressor does best. WHAT IS A COMPRESSOR?
  • Page 8: Prochannel Control Explanations

    VC3Q - User's guide Pro Channel to be remembered. The rule is that when 'lift' is used, it's often necessary to compensate by reducing the input gain. Note, always start with the EQ controls set to the 'flat' position; that is, with the three pointers set at the '0' position at the top of each control.
  • Page 9 VC3Q - User's guide Pro Channel 'RELEASE' sets the time during which the path gain returns to normal after compression. Generally, the longer the time, the less obvious is the compression. LF controls the volume of low frequencies in the audio spectrum. This is a 'shelving' control with the full level of lift and cut available at and below 80Hz.

    POWER - Power input is 12Volt AC only. POWER THE PROCHANNEL ONLY FROM THE JOEMEEK POWER SUPPLY PROVIDED. USE OF OTHER POWER SUPPLIES WILL DAMAGE THE PROCHANNEL AND WILL INVALIDATE ALL WARRANTIES.

    VC3Q - User's guide Pro Channel USING THE INPUT AMPLIFIER Selection of 'MIC' or 'LINE' input is automatic; the microphone XLR input socket is disabled when you plug a jack-plug into the line (or instrument) input. Turn the INPUT GAIN knob down to minimum then, If you are using a capacitor microphone, plug in the microphone into the XLR socket, then switch on the phantom power by pressing in the 'Phantom' switch.

USING THE EQUALIZER Always start with the equalizer controls set to '0' (the control knobs set vertical).

    VC3Q - User's guide Pro Channel COMMON PROBLEMS 1) The microphone doesn't work! - Have you got something plugged into the line input? (this disables the microphone input) - Is the phantom power on? (capacitor microphones). - Is the output volume control up? 2) Got signal going through, but no compression.

    THE COMPRESSOR The built-in JOEMEEK compressor is slightly different from the big studio units like the JOEMEEK SC2.2 or SC4, so that it is easier to operate with musical instruments. The 'ATTACK' control is variable so that the impact of the compression sound can be varied from a gentle effect (with the attack adjusted fast) to more powerful sounds with longer attack times.

THE EQUALIZER The equalizer is so called because it 'equalizes' or corrects the sound. It does this by modifying the relative volume levels of the various frequencies in the audio signal.
  • Page 18 VC3Q - User's guide Pro Channel THE POWER SUPPLY An external 12V AC power supply provides the power for the unit. DO NOT ATTEMPT TO POWER THE UNIT FROM ANY POWER SUPPLY OTHER THAN THE ONE SUPPLIED WITH THE UNIT. Circuitry inside the VC3Q converts the 12V AC into 14.5-0-14.5V and a 48V DC supply for the phantom power.
