Harman SoundCraft MONITOR 2, User Manual

USING MONITOR 2

Mono Input Channel

XLR Input

The UltraMic Plus padless input preamp is designed to accept BALANCED or

UNBALANCED signals at a wide range of input levels up to +28dBu.  When

using microphones, professional dynamic, condenser or ribbon mics are best

because these will be LOW IMPEDANCE.  You can use low-cost HIGH

IMPEDANCE mics, but the level of background noise will be higher.  If you

press the 48V switch down the socket provides a suitable powering voltage

for professional condenser mics (this is also known as Phantom Power). 

Each input is provided with a male XLR-type SPLIT OUT connector, which

enables mic signals to be fed directly to a Front-of-House mixer without the

need for specials cables or splitter boxes.  Always provide 48V powering

from the Monitor 2 console if required, and turn off the powering at the

FOH console.  

An internal jumper option is provided to allow the ground connection to the

SPLIT OUT connector to be lifted to prevent ground loops in certain

installations.  

ONLY connect condenser microphones with the 48V

powering OFF (switch UP), and ONLY turn the 48V

powering on or off with all output faders DOWN, to

prevent damage to the mixer or external devices.  If the

SPLIT OUT connectors are used to feed another mixer,

the MONITOR 2 console should be powered up first, or

the faders on the FOH console should all be down when

the MONITOR 2 is powered up or split feeds connected.

DO NOT turn on the +48V when using unbalanced sources

or line level signals, which may be damaged by the phantom

power voltage on pins 2 & 3 of the XLR connector, and

ONLY connect the SPLIT OUT feed to inputs which can

tolerate phantom power voltages if the powering is in use.

PHASE REVERSE

Pressing this switch reverses the polarity of the input, providing a

convenient method of compensating for incorrect wiring or microphone

placement. In some circumstances it may be found that pressing PHASE

REVERSE will help with feedback avoidance.  The switch should normally

be released when not required.  Note that the SPLIT OUT feed is NOT

affected by this switch.

SENS (Sensitivity)

This knob sets how much of the source signal is sent to the rest of the

mixer.  Too high, and the signal will distort as it overloads the channel.  Too

low, and the level of any background hiss will be more noticeable and you

may not be able to get enough signal level to the output of the mixer.  

Setting the knob to the `0’ mark gives unity gain for line level signals.  See

`Setting Up & Troubleshooting’ on page 8 to learn how to set SENS

correctly.

100Hz HI-PASS FILTER

Pressing this switch activates a steep 18dB per octave filter which reduces

the level of bass frequencies only.  Use this in live PA situations to clean up

the mix, reducing stage rumble or ‘popping’ from microphones.

INSERT POINT

The unbalanced, pre-EQ insert point is a break in the channel signal path,

allowing limiters, compressors, special EQ or other signal processing units to

be added in the signal path.  The Insert is a 3-pole ‘A’ gauge jack socket which

is normally bypassed.  When a jack is inserted, the signal path is broken, just

before the EQ section.  The Send may be tapped off as a line level, pre-fade,

pre-EQ send of a mic source if required, using a lead with tip and ring

shorted together so that the signal path is not interrupted.

EQUALISER

Powerful, corrective Equalisation (EQ) is essential in live situations to cope

with varying venue acoustics and original signals which may be far from ideal.

Each Monitor 2 input is provided with a comprehensive 4-Band EQ section,

with two swept mids for extra control.

HF EQ

Turn clockwise to boost high (treble) frequencies (12kHz and above) by up

to 15dB, adding crispness to cymbals, vocals and electronic instruments.

Turn anticlockwise to cut by up to 15dB, reducing hiss or excessive sibilance

which can occur with certain types of microphone.  Set the knob in the

centre-detented position when not required.  

MID EQ (HMID & LMID)

There are two pairs of knobs which work together to form HI and LO MID

frequency EQ sections.  The lower knob in each pair provides 15dB of boost

and cut, just like the HF EQ knob, but the frequency at which this occurs can

be set by the upper knob over a range of 550Hz to 13kHz (HMID) or 80Hz

to 1.9kHz (LMID).  This allows some truly creative improvement of the

signal in live situations, because the mid bands cover the range of most

vocals.  Listen carefully as you use these controls together to find how

particular characteristics of, for instance, a vocal signal can be enhanced or

reduced.  Set the gain (lower) knob to the centre-detented position when

not required.  Note: Q is set at 1.5.

LF EQ

Turn clockwise to boost low (bass) frequencies (60Hz and below) by up to

15dB, adding warmth to vocals or extra punch to synths, guitars and drums.

Turn anticlockwise to cut low frequencies by up to 15dB for reducing hum,

stage rumble or to improve a mushy sound.  Set the knob to the centre-

detented position when not required.

EQ SWITCH

The EQ switch bypasses the Equalisation section when released.  Alternately

pressing and releasing the switch provides an easy way of comparing the

equalised and unequalised signals.
