EURORACK MX1604A

A good vocal signal can be enhanced by applying a significant boost in the 12 kHz region or higher, above the

nasty sibilance region. This is especially effective if youve got a de-esser patched post-EQ.

+ Use the Lo Cut to tighten up channels in a mix: maybe remove it only for the bass, kick drum,

toms, tablas, didgeridoo and other deliberate subsonics (when recording classical music ig-

nore this advice).

With the LF set to boost, and the Lo Cut switch activated, you have pretty much got a peak response rather

than shelving at the bottom. Good for tight but deep bass.

Remember EQ contouring can be done with cut as well as with boost. Cutting away the top and bottom, then

pushing up the Gain is equivalent to mid range boost! EQ is not a one way street!

Always reset a channels input Gain (or external devices output level) after altering the amount of desk EQ cut

or boost applied.

7.2 Gain optimization

PFL (Pre-Fader Listen) is the way to set a desk level. Setting up the channel input Gain is discussed in the

essential section 5. Master Aux Send levels are fixed at Unity Gain. As the mix progresses, more and more

channels are likely to be sending to effects via the Aux buses, and its best to PFL all sends just before setting

up for the final mix.

Outboard reverbs etc. should all be made to work hard. Theres no point in having an 85 dB dynamic range if

the input meter of your reverb is barely flickering. On the other hand, digital distortion is not one of the nicer

noises around. Youll have to rely on your ears to detect digital distortion, since different outboard processors

calibrate their meters differently.

If you hear distortion, turn down the input on the FX unit, and turn up the desks Aux Return input.

99 times out of 100 distortion in the Aux Send / FX / Aux Return loop will come from the FX unit (FX gain too

high), and the same goes for a high noise level (FX gain too low).

Noisy FX (or synth) returns can be greatly improved by the addition of single-ended noise reduction between FX

output and Aux (or channel) Returns. The BEHRINGER DENOISER SNR2000 is ideally suited for this pur-

pose.

Using analogue single-ended noise reduction can help warm the sound of certain digital reverbs which sound

too cold/metallic, and also give that Echoplex sound to digital delay decays.

Analogue multitrack tape should be driven quite hard, since its dynamic range (without noise reduction) is

likely to be 20-30 dB worse than other elements in the recording chain. Try to record bright. You can always

mix back duller. Brightening up an off-tape signal will bring up the level of tape noise. With digital tape or hard

disk you have plenty of dynamic range, and treble pre-emphasis is not often necessary. Just dont let the

signal distort!

When mixing or recording, keep the channel fader levels around or below 0 dB. If you do find the faders

creeping up or down, apply a suitable offset over all channel faders, and try to control your bad habit in

future!

8. CONNECTIONS

8.1 EURORACK MX1604A connections

AC Power In.

For connecting the mixer to the Power Supply Unit (PSU). Always connect mixer and PSU before you

connect the PSU to the mains supply.

Power switch

Once the PSU is connected to the mains supply, you may switch on your EURORACK. Allow 1 minute

after powering up for the system to equilibrate before setting input gains.
