-
21 Level
Turn this knob to adjust the level of this section's Input (20).
-
22 Tuner
If you wish to connect a tuner, use this 6.3 mm/1/4" mono jack. This bus
remains active when you mute the era 1 .
-
23 Footswitch
This 6.3 mm/1/4" stereo jack accepts an optionally available two-way
footswitch such as the Hughes & Kettner FS-2. The first button mutes the
amp (LED 1 on the FS-2 lights up). The second button switches the onboard
effects off and on (LED 2 on the FS-2 lights up when they're switched off ).
For more on internal effects, see section 1.1, Top Panel, FX Preset and FX
Vol.

Input CH 3
This 3.5 mm stereo mini jack serves as the input for an external audio
source such as a smartphone, MP3 player, etc.
-
25 DI Out
This balanced XLR output sends the CH 1 and CH 2 channels' balanced
preamp signal to another destination, say, a PA's mixing console. This
signal is dry—that is, without internal effects and the FX loop/CH 4 added
in—and it may be tapped before or after the EQ section. FYI: A balanced
signal is less susceptible to interference when using long cables to cover
greater distances.
-
26 Pre/Post EQ
This button determines at which point in the bus the DI Out signal is
tapped, before or after the tone controls (pre and thus without EQ or post
and therefore with EQ).
Button up (not pressed) = before the EQ section
Button down (pressed) = after the EQ section
-
27 Ground Lift
When activated, the Ground Lift button severs the ground connection (pin
1). This is a standard feature designed to eliminate humming or buzzing
caused by ground loops. In the event of annoying hum or buzz, press this
button to put a stop to it.
Button up (not pressed) = deactivated
Button down (pressed) = activated

Phones
This 6.3 mm/1/4" stereo jack is the built-in stereo headphone amp's
output. The era 1 's loudspeaker is muted when you plug in headphones.
This output delivers the full package—a composite of the signals of CH 1
and CH 2, of a playback device connected to CH 3, of internal effects, and
of the FX loop/CH 4 bus. This means you can enjoy the era 1's full sonic
glory in your headset when you've muted the amp by plugging phones in.
-
29 Line Out
This 6.3 mm/1/4" stereo output jack sends the unbalanced, line-level,
stereo preamp CH 1 and 2 signal to a mixing console, recording device, or
the like. This is a post-EQ composite signal that includes internal effects as
well as the CH 3 and FX Loop/CH 4 signals.
-
30 Line Out Level
Turn this knob to adjust the Line Out signal's level, independently from the
Master Volume.
-
31 Optical Out
This optical S/PDIF Toslink audio output sends the era 1's master audio
signal to target devices equipped with an optical Toslink input. This signal
will serve you well for recording purposes. Typical target devices are
computer soundcards, digital mixing consoles, audio interfaces and stereo
systems.
Toslink is an electrically nonconductive optical fiber. That means no
ground loops (and no hum). It is also insensitive to electrical and magnetic
interference.
