[1] MIC – LINE INPUTS
RCF E12 provides 6 mono Mic Line inputs via combo connectors. The Balanced XLR Microphone
preamp input supports sources with a gain range from +6dB to +60dB. The coaxial TRS jack supports
line signals with a gain of -24dB to +30dB. All the E12’s MIC-LINE inputs are supplied with a 80Hz
Hi-pass filter. Enable the 80Hz Hi-Pass filter when using microphone for voice to reduce low frequency
pop, bump and rumble noises. Connect your Microphones and your line sources here.
[2] INPUTS 3 & 4
Line inputs 3 & 4 add the selectable Hi-Z input feature. The Hi-Z input is very useful when connecting
low level musical instruments like Electric or Acoustic Guitars or Bass Guitars with passive pick-up.
[3] STEREO INPUTS
TRS jacks 7/8, 9/10 and 11/12 provide Stereo inputs for line sources with +/- 15 dB gain
[4] STEREO RETURN INPUTS
TRS Jacks provide a further stereo line input with level control from -∞ to +10dB. Ideal when using an
external effects unit to send the effect signal back to the mixer. STEREO RETURN is the ideal connection
for stereo sources like background music players.
[5] USB POWER
This Type A USB port provides a power of 5V – 500mA ideal for power up of a USB lamp or fan or to
recharge any USB mobile devices.
[6] COMPRESSORS
Input channels 1 to 4 are provided with intuitive and powerful single control dynamic compressors.
With thresholds and ratio parameters properly designed the E12 compressors allow even the most
dynamically demanding signals to be controlled.
[7] +48V SWITCHES
Dedicated to the Mic input this switch allow enabling of the +48V Phantom Power to the Mic input: 1-6.
Enabling of the Phantom power is necessary only in presence of Condenser and Electret Microphones
or in case of use of D.I. boxes.
[8] EQ
All the E12’s mono channels are provided with a sophisticated and precise 3-band parametric EQ.
Low frequency control sets in at 100Hz with a gain of +/-15dB and shelving curve. Hi frequency
control sets in at 10kHz with a gain of +/-15dB and shelving curve. Mid frequency control works in
a selectable frequency range between 100 Hz and 8 kHz with a gain of +/-15dB. Mid band feature
a switch for the selection of the band “Q”. The selection is between WIDE or NARROW “Q” action.
[9] Stereo channels are provided with a 3-band EQ
