Things to do before operating the amp

• Please read these instructions carefully, particularly the notes on safety, before operating the amp.

• The manufacturer disclaims any liability on responsibility whatsoever for any damage or defect to this and other devices resulting from misuse.

• Before you plug this amp into a mains power outlet, make sure its Power and Standby switches are off and that the voltage rating indicated on its rear panel matches your local mains current.

• A word of warning before you fire up your era 1 era 1 / era 2 era 2: It’s loud, and high volume levels can cause hearing damage. To avoid very loud and unwelcome surprises, make a habit of backing the Volume knob of the guitar connected to the era 1 era 1 / era 2 era 2 all the way down before switching on the amp! Version 2.5 10/20173 era 1 / era 2 – Manual 1.2 1 Connections and Control Features The era 1 era 1 / era 2 era 2 features two identical independent channels (CH 1 and CH 2) for instruments and vocals, a third input (CH 3) for outboard signal sources such as an MP3 player, and a fourth input (CH 4) for external effects, a mixing console or pre-amped instruments.It also provides a versatile DI Out, an adjustable Line Out, a Channel Out (via FX Send), a headphones output (Phones) and an Optical Out. This gives you an arsenal of very practical outputs that will get the job done right for live performances, recording sessions and any other professional gig.Heads up: To avoid loud surprises, make a habit of turning the Volume knob in the Master section all the way down—that is, as far left as it will go—before powering up the amp.

CH 1 / CH 2The following descriptions of features 1 through 11 apply to both identical channels CH 1 and CH 2.

1 Clip This LED lights up to let you know that the incoming signal is overdriving the input stage of the given channel, CH 1 or CH 2. It's not a problem if it flashes briefly or flickers, but if it stays on for any length of time you will have to turn the Gain knob to the left to reduce the amplification. If that doesn't solve the problem, you can reduce the gain further by pressing the –10 dB button. If both Clip LEDs light up at the same time, one of the inputs of CH 3 or CH 4 is saturated. An occasional brief flashing or flickering does not pose a problem, but if they light up continuously you will have to reduce the level at the signal's source device. Turn it down until the two Clip LEDs extinguish.

2 –10 dB This switchable –10 dB pad serves to cut input gain. Push it when Clip lights up to tell you incoming signal is overdriving the input stage and the LED light does not extinguish when you back off the Gain knob.Button up (not pressed) = deactivatedButton down (pressed) = activated

3 Shape This button activates a pre-EQ that slightly cuts the midrange and boosts the top end to accentuate the fundamental bass and lower midrange frequencies and bring out the overtones. Try both options, with or without Shape, to see which voicing works best for you. The LED next to the button lights up when Shape is activated.

4 Mute Push this button to silence the given channel, CH 1 or CH 2. The signal will then be routed exclusively to the Tuner output. The LED next to the button lights up when Mute is activated. If a footswitch is connected, the Mute button will not function. Muting the amp can then only be performed via the footswitch (see also 23: Footswitch).

5 Gain This knob adjusts the input's gain level to suit the incoming instrument or mic signal.

6 EQ/Mode 2 This button selects EQ modes. This very special feature of the era 1 era 1 / era 2 era 2 gives you two fully independent sets of tone controls called EQ Mode 1 and EQ Mode 2 with different variable frequencies for the two channels CH 1 and CH 2. The Mode 2 LED lights up when EQ Mode 2 is activated. EQ Fundamentals The tone controls of a conventional EQ section boost or cut fixed frequencies. That is not the case with the era 1 era 1 / era 2 era 2, where the Bass, Mid and Treble knobs address different frequencies as determined by the selected EQ mode. This gives you a far greater range of sound-shaping options. For example, you could use different EQs for different instruments. Learning by doing works best: Try adjusting the Bass, Mid and Treble knobs in both modes to discover which EQ voices your instrument best and feels good to you. That's what this is all about—finding the tone and response that works for you.Note: The era 1 era 1 / era 2 era 2 is designed to reinforce your instrument's natural sound so that the amplified signal sounds exactly like your instrument and no other, only louder. That unique sound is to remain intact even when you adjust the EQ. These controls are voiced so that they don't color the natural Mute Shape Clip –10 dbMode 2Gain EQ Bass Mid

• 日本語4 era 1 / era 2 – Manual 1.2sound of your instrument. In some cases, their effect may be more subtle than is normally the case with standard EQs. Hands-on tips Steel-string vs. nylon-strings acoustic guitars: The EQ Mode 1 tone controls favor steel strings and are usually more effective at voicing the frequencies of that type of guitar. The EQ Mode 2 tone controls excel at shaping the sound of guitars with nylon strings.Using a microphone to amplify your voice: If you have a low voice, the EQ Mode 1 tone controls are generally the better choice for shaping its frequencies. The EQ Mode 2 tone controls tend to favor higher voices. This gives you an idea of where to start, but again, your best bet is to just try it out.

7 Bass This knob cuts and boosts bass frequencies by +/– 10 dB (peak EQ). The knob has no effect on frequency response when set to the center or 12 o’clock position.

8 Mid This knob cuts and boosts midrange frequencies by +/– 6 dB (peak EQ). The knob has no effect on frequency response when set to the center or 12 o’clock position.

9 Treble This knob cuts and boosts treble frequencies by +/– 10 dB (peak EQ). The knob has no effect on frequency response when set to the center or 12 o’clock position.

Changes to FX parameters here are effective across both channels, regardless of the channel in which they are made."DT" stands for delay time, or the time between echoes / repeats."HF damping" attenuates the high-frequency (HF) components in the reverb signal to take the harsh edge off and achieve a warmer, fatter tone."ms" is shorthand for milliseconds.

11 FX Vol. This knob adjusts the volume of the selected effect preset. Turn it to the far left to bypass the FX section and remove presets from the signal path.Customizing FX presets The era 1 era 1 / era 2 era 2 has a hidden function that lets you adjust presets' parameters. This can even be done separately with most FX types for each channel. Here's how to adjust parameters:1. Use the FX Preset (10) selector to dial in the preset (no. 1-16) that you wish to edit in the given channel.2. Press EQ/Mode 2 for three seconds. Mode 2 LED flashes to indicate the amp is now ready for programming.3. Turn the Aux In knob to adjust the selected parameter (see the FX parameter table's last column).4. To save your changes, press EQ/Mode 2 for three seconds, until the Mode 2 LED lights up continuously. 5. To exit without saving changes, press EQ/Mode 2 briefly to return your amp to its standard operating mode. The Mode 2 LED will flash briefly to confirm the cancellation.Note: Only one effects preset can be customized at a time. If the FX Preset (10) selector is moved during the programming process, this will cause any changes to be cancelled (Mode 2 LED will flash quickly). Off Aux In Notch Volume CH 3 MASTER

12 Aux In This knob adjusts the volume of the connected signal source. Section 1.2, Rear Panel CH 3/Input, explains how to connect a playback device. Bass Mid Treble Off FX Preset FX Vol.

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.

14 Volume 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 with a jack plug.

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 an XLR connector.

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 specifications of semi-pro and professional microphone preamps made by various manufacturers, you'll find 9, 12, 15, 24 and 48 volts indicated for their phantom power supply. Users can hardly be blamed if they find this confusing. Bar a few exceptions, condenser microphones will work just fine 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 amplifiers 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. 1/4" XLR PhantomPower*OQVU CH 1 PhantomPower*OQVU CH 2CH 3 Level'9 4FOE *OQVU5VOFS'PPUTXJUDI '9-PPQCH 4 *OQVU

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 era 1 / era 2 era 2.

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.

24 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

28 Phones This 6.3 mm/1/4" stereo jack is the built-in stereo headphone amp's output. The era 1 era 1 / era 2 era 2'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 era 1 / era 2 era 2'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 era 1 / era 2 era 2'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.

32 Auto Sleep Commission Regulation (EC) no. 1275/2008 requires electronic devices to be equipped with a power-saving function that switches off the device after a specified period of non-use. That's what the era 1 era 1 / era 2 era 2's Auto Sleep does. Auto Sleep can be activated and deactivated using a thin, pointed object to press the recessed button next to the speaker jack.

off Button up (not pressed) = deactivated Button down (pressed) = activated The era 1 era 1 / era 2 era 2 ships with Auto Sleep activated, so the amp will shut down if it's left to idle continuously for around 90 minutes. If Auto Sleep shuts the amp down, you can wake it up by flipping the Power switch off and back on again.

33 Power Set this switch to On to get the mains power flowing and to Off to cut it off again.

34 Mains Connect the factory-included power cord (Mains Lead) to this socket. Before you power the amp up, make sure the voltage rating indicated on the device matches your local mains current.

35 Factory Reset To trigger a factory reset, use a thin, pointed object such as a paper clip to press and hold for five seconds the recessed button in the round hole next to Auto Sleep. The LEDs on the control panel will flash twice to confirm that the amp's factory settings have been restored. 2 Standard Setup and Cable Connections 1IBOUPNPower*OQVU CH 1 1IBOUPNPower*OQVUCH 2CH 3Level'9 4FOE *OQVU1IPOFT 5VOFS-JOF0VU %*0VU 'PPUTXJUDI'9-PPQCH 4*OQVU0VU0QUJDBMLevel 1SF1PTU (SPVOE Lift Tuner
