13 Notch
This knob adjusts a notch filter that lets you tame resonance, feedback
and other interference frequencies by addressing and attenuating a specific
target frequency. First you'll have to find the frequency that's giving you
trouble by slowly turning the knob, which ranges from 40 to 180 Hz. The
filter cuts that frequency as soon as you dial it in. Turn the knob to the far
left to bypass the notch filter. This takes the filter out of the circuit so that
it no longer affects the amp's frequency response.

This knob adjusts the amp's overall volume.

15 On/Off LED
This indicator lights up when the amp is on.

16 Input CH 1 and CH 2
These two ports are combination instrument/microphone inputs. When
you plug in a 6.3 mm/1/4" instrument jack plug or an XLR mic connector,
the era 1 era 1 / era 2 era 2 automatically detects the connector type and activates a
preamp designed for an instrument or microphone.
The jack is configured as an unbalanced input for instruments
with passive or active pickups when you insert a cable fitted
1/4"
with a jack plug.
x
For unbalanced instrument signals, you will need a (mono or stereo)
6.3 mm/1/4" music instrument cable. Quality matters, so be sure to always
use a well-made cable that does not pick up interference or otherwise
degrade your sound.
The port is configured as a balanced input for dynamic and
condenser microphones when you plug in a cable fitted with
XLR
an XLR connector.
x
For balanced microphone signals, you will need an XLR microphone
cable. Quality matters, so be sure to always use a well-made cable that does
not pick up interference or otherwise degrade your sound.

17 Phantom Power
Switch this button on to route phantom power to an instrument (9 V) or
mic (24 V) that is plugged into the input and requires a power supply. The
LED lights up when you do. Switch phantom power off for an instrument or
mic that does not need this power supply. The LED will extinguish.
Heads up: Be sure to check if the connected mic or instrument requires
and can handle phantom power. If not, it may be damaged. This is often
the case with dynamic microphones made anywhere from 20 to 30 of more
years ago. In case of doubt, please contact the manufacturer of the device
you wish to connect!
FAQ about 24-volt phantom power:
Doesn't my condenser mic require 48 volts?
If you review the specif ications of semi-pro and professional microphone
preamps made by various manufacturers, you'll f ind 9, 12, 15, 24 and 48
volts indicated for their phantom power supply. Users can hardly be blamed
if they f ind this confusing. Bar a few exceptions, condenser microphones will
work just f ine at an operating voltage between 12 and 48 volts. The mic's
circuitry won't detect any difference between 24 and 48 volts, so the variance
in phantom power will have no effect on its dynamic response. Whatever
voltage supply you choose, know this: It is important that the phantom
power supply delivers the voltage stipulated by statutory regulations. Rest
assure that era series era series amplif iers comply with this standard.

18 FX Loop/CH 4
A parallel FX Loop. Connect FX Send (19) to the external effect device's
input and Input (20) to the device's output. Alternatively, you could use the
input of era 1 era 1 / era 2 era 2's fourth channel, CH 4, as an FX return.
-
19 FX Send
Use this CH 1 and CH 2 stereo 6.3 mm/1/4" output jack to address an
external effect device. FX Send carries an unbalanced, line-level preamp
signal (post EQ and without internal effects), so this jack may also be used
as a channel output, say, to route the signal to a mixing console for analog
recording or the like. If you plug in a mono rather than a stereo cable, you
can use FX Send as an output only for CH 1.
-
20 Input
Use this stereo 6.3 mm/1/4" input jack to patch in a signal from an outboard
effects device (in combination with FX Send in an FX loop). This jack can
also serve as a CH 4 input for other line-level signal sources, for example, a
pre-amplified instrument that doesn't need EQ, a mixing console, a drum
computer, and so on.
