The Sonnet 60 acoustic amplifier brings a simple control set with intuitive design to give you the pinnacle of acoustic tone.Each channel of the Sonnet 60 has been designed with your performance in mind. Channel 1 combines a 3 band EQ, REVERB level control and a PHASE switch to control unwanted feedback. Channel 1 also has a SHAPE feature, offering two different preamp voicings for your acoustic guitar.Channel 2 features a combination XLR/jack input – perfect for a microphone or another instrument – with LOW and HIGH EQ controls, independent REVERB level control and SHAPE feature.The Sonnet 60 also features a natural sounding digital reverb, with two reverb types and the ability to adjust the reverb tail via the REVERB TIME control on the front panel.H.P. FILTER (High Pass filter) and BRILLIANCE controls provide further control over your tone, allowing you to sculpt how your acoustic guitar is amplified.A USB connector allows for sending a processed output into a computer for recording purposes and a balanced XLR D.I. OUTPUT also allows the signal to be connected to external devices for practicing, recording or live use.The MP3 / LINE IN jack allows you to connect your Sonnet 60 to a music device or drum machine to play along to, or use the Bluetooth capability of the amp to make connecting to an external device even easier.

Front Panel

Channel 1

  1. Input 1 – 1/4″ JackPlug your instrument in here. This channel features a very high impedance input circuit (hi-Z). This is ideal for direct connection to instruments with piezo pickups. Always use a good quality screened instrument lead.
  2. PhaseThis will reverse the phase of the signal within the preamp. Use this to help to suppress acoustic feedback.
  3. GainThis controls the input gain of Channel 1. Turning it clockwise increases the input gain. The Sonnet preamps each include specially designed ‘dynamics control processing’. At low signal levels and GAIN settings this is not applied and is therefore transparent. The higher the signal level and higher the GAIN is set, then the more the dynamics control will come into operation. This has two advantages: Firstly it smooths out the peaks that can sound harsh on electronically amplified acoustic instruments. The result is more like a nice studio recording. Secondly it allows much higher headroom with the preamp and therefore less likely to clip. This is like having an in-built sound engineer helping you sound your best at all times.
  4. ShapeThis switches between two basic EQ shapes. In the ‘out’ position, the EQ is relatively flat which will be a good natural sounding starting point for most instruments. The ‘in’ position applies a mid cut as well as some low and high boost for an alternative sound that can help create definition and space within a mix of instruments and/or vocals. In both settings the normal channel EQ controls can be used to further fine tune the tone.
  5. LowThe LOW control adjusts the amount of low-end frequencies in your tone. This amp has active tone shaping circuits which allow the low frequencies to be precisely controlled for both the desired sound and also to help control instrument resonances.
  6.  MidThe MID control adjusts the amount of middle frequencies in your tone. The middle frequencies are particularly important in setting the amount of ‘body’ your tone has.
  7. HighThe HIGH control allows exact adjustment of the treble frequencies within the sound. At low settings (counter clockwise) the sound will be warm and darker in character. As the control is increased (clockwise) the sound will become brighter and more lively.
  8. ReverbThe Reverb control sets the overall level of the reverb effect. With the control fully counter clockwise there will be no reverb. Turning the control clockwise will increase the amount of reverb.Channel 2
  9. Input 2 – Combination XLR / JackPlug your microphone or another instrument in here. Always use good quality screened XLR or instrument leads.
  10. GainThis controls the input gain of Channel 2. Turning it clockwise increases the input gain. As with Channel 1, this channel also has in-built ‘dynamics control’ and operates in the same way.
  11. ShapeThis switches between two basic EQ shapes, operating in the same way as Channel 1.
  12.  LowThe LOW control adjusts the amount of low-end frequencies in your tone. This amp has active tone shaping circuits which allow the low frequencies to be precisely controlled for both the desired sound and also to help control instrument resonances.
  13. HighThe HIGH control allows exact adjustment of the treble frequencies within the sound. At low settings (counter clockwise) the sound will be warm and darker in character. As the control is increased (clockwise) the sound will become brighter and more lively.
  14. ReverbThe Reverb control sets the overall level of the reverb effect. With the control fully counter clockwise there will be no reverb. Turning the control clockwise will increase the amount of reverb.
  15. Reverb TypeThe switch enables you to select between two reverb types;Hall – This simulates the lush natural reverb of a large hallPlate – This simulates the shine and density of a vingate studio plate reverbThis will apply to both Channel 1 and Channel 2 reverb controls.
  16. Reverb TimeThis control adjusts the length of the reverb tail. At minimum settings the reverb tail will be short and at maximum settings the reverb tail will be long. We recommend trying different Reverb levels and Reverb times to achieve the effect desired.
  17. H.P. FilterThis controls a High Pass Filter. Adjust this trim pot to roll off low-end frequencies from your amplifier’s output. At the minimum setting the frequencies filtered will be below 25Hz, and at the maximum setting, the frequencies filtered will be below 180Hz. Rolling off low frequencies can help with definition in a mix with other instruments.
  18. BrillianceAdjust this trim pot to apply an increase or decrease to the higher frequencies of your amplifier’s output. At maximum settings this will result in a brighter, sharper response from your tone. At lower settings, the tone is warm and mellow.
  19. MasterThis controls the overall volume of your amplifier. Turning it clockwise increases the volume.
  20. Power Indicator LightThe Power Indicator will light when the amplifier is switched on.
  21. BluetoothYour SONNET 60 Bluetooth amplifier is equipped with Bluetooth connectivity for wirelessly streaming your favourite music and backing tracks. Press this switch to pair a Bluetooth device to your SONNET 60 Bluetooth amplifier and toggle between the modes of operation (see below).Discoverable Mode (slow LED flash)

    To connect a Bluetooth device to your SONNET 60 Bluetooth amplifier for the first time you must make a ‘pairing’ between the two devices. To pair, simply press and hold the Bluetooth switch on your SONNET 60 Bluetooth amplifier until the Bluetooth LED displays a slow flash. In this state other Bluetooth devices are able to ‘see’ your SONNET 60 Bluetooth amplifier (hence the term ‘Discoverable’) and can make a request to pair.

    Whilst the Bluetooth LED is flashing slowly, go to the Bluetooth Settings page of your Bluetooth device and look for your SONNET 60 Bluetooth amplifier in the list of available devices. Your amplifier will be identified as ‘SONNET BT’. When ‘SONNET BT’ appears, simply select this device and wait a few moments for the pairing to be made. You will hear an audible tone from the amplifier to indicate that a device has been successfully connected.If a pairing has not been made within the Discoverable Mode timeout window, the Bluetooth connectivity will switch off and will wait for user input in order to attempt a new pairing. Simply press and hold the Bluetooth switch again to enter Discoverable Mode and restart the pairing process.Pressing the Bluetooth switch while in Discoverable Mode will put your SONNET 60 Bluetooth amplifier into Scanning Mode.Scanning Mode (fast LED flash)

    Scanning Mode is used to reconnect any previously paired Bluetooth devices to your SONNET 60 Bluetooth if they have travelled out of range or have been disconnected. Ensure your previously paired Bluetooth device has Bluetooth connectivity switched on. Press the Bluetooth switch once to put the SONNET 60 Bluetooth into Scanning Mode; your amplifier will ‘scan’ for previously paired devices within range and attempt to reconnect, starting with the device that was most recently connected. You will hear an audible tone from the amplifier to indicate that a device has been successfully reconnected.If you have previously paired any Bluetooth Devices to your SONNET 60 Bluetooth amplifier it will power on in Scanning Mode. If your Bluetooth device is within range and has Bluetooth connectivity switched on, your amplifier will automatically reconnect to your device, allowing you to start streaming your music straight away. Pressing the Bluetooth switch from Scanning Mode will set your amplifier to Discoverable Mode in order to begin pairing a new device. At any time, you may disconnect your Bluetooth device from your amplifier by either pressing and holding the Bluetooth switch on the amplifier front panel for 3 seconds or switching off the Bluetooth functionality of your device. You will hear an audible tone from the amplifier to indicate that a device has been disconnected.

  22. Bluetooth LEDThe Bluetooth LED indicates which mode the Bluetooth is in (Discoverable/Scanning). When the Bluetooth LED is unlit the Bluetooth connectivity is not active.Rear Panel
  23. USB Audio SocketThis Type B USB socket is for connection to a computer via a suitable lead (not supplied). Standard audio drivers are used to connect the amplifier to a PC, Mac or other applicable recording device. No specific drivers are required.For a guide on low latency USB recording visit: Always connect the amplifier via a main USB port, often found on the rear of the computer. The amplifier will appear as an audio capture device within recording software.
  24. Ground LiftThis switch can be used to remove the circuit-to-chassis ground connection of the XLR output, which can help if experiencing hum or noise upon connecting to an external device. If you do experience a hum when connecting the XLR Output (25) to an external device, engage the Ground Lift by depressing the button to lift the ground on the circuit.
  25. Mix D.I. XLR OutputThis output is a low impedance, balanced XLR output for connecting directly to a mixer or stage box. This will send a strong low noise signal, including all front panel processing (with the exception of the master control), to be used externally. Use a good quality screened/balanced microphone type cable.
  26. MP3 / Line InThis is a stereo mini jack input. Connect the output of your audio device here and adjust the player’s volume to match that of your instrument or voice to enable you to play and/or sing along.NOTE: This connection is stereo, but will mix the incoming stereo signal and output a mono version.
  27. Footswitch (Optional Purchase)The optional FS-17 footswitch, or any 2-way latching footswitch can be connected here. The first switch labelled ‘Mute’ will mute the whole amplifier, and the second switch labelled ‘Reverb’ will defeat the reverb on both channels.
  28. Power SwitchThis switch is used to turn the amplifier on and off.
  29. Mains InputThe supplied detachable mains power cable is connected here. Always ensure the Power Switch (28) is in the OFF position before applying mains power. The cable should only be connected to a power outlet that is compatible with the voltage, power and frequency requirements stated on the rear panel. Never break off the earth (ground) pin on the mains cable. If in doubt seek advice from a qualified technician.

Tilt-Back and SA-2 Stand Adaptor

30. Tilt-back StandOn the base of the Sonnet 60, there is a threaded stand socket with an adjustable tilt-back stand. Rotate the tilt-back stand anti-clockwise to adjust the desired angle of tilt. Rotate the tilt-back stand clockwise to lower the angle of tilt, or continue rotating to return the tilt-back stand into the base of the amplifier.

31. SA-2 Stand Adaptor (Optional Purchase)The optional SA-2 Stand Adaptor can also be mounted on the Sonnet 60, enabling the amplifier to be placed on a speaker stand. Firstly, remove the tilt-back stand from the threaded socket then mount the SA-2. Rotate the SA-2 clockwise until it is flush against the bottom of the amplifier. To remove, rotate the SA-2 anti-clockwise.

WARNING! Ensure the SA-2 is securely mounted to the base of the Sonnet 60 before placing on a speaker stand. Failure to do so may result in unnecessary stress being placed on the threaded socket and may cause damage to the structure of the amplifier.
