[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.

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.
