Precautions / Safety Instructions

Power Supply
The Warwick Gnome is powered by an IEC power cable, which provides AC power to the unit. Connect the IEC power cable to provide power. Improper line voltage can cause serious damage to the unit, always check the line voltage marking on the amplifier before you connect the IEC power cable. Unplug the unit when not in use or during electrical storms.

Connections
Always turn off power to all other equipment before connecting or disconnecting. This will help to prevent malfunction and damage to any of the devices used.

Cleaning
Clean only with a soft, dry cloth.

Handling
Do not apply excessive force to the switches or controls. Do not block any ventilation openings. Install in accordance to the instructions. Do not let paper, metal, dirt or other objects come into contact with the device or its connections. Take care not to drop the device and do not subject it to shock or excessive pressure. The unit should be connected to a mains socket outlet with a protective earthing connection. Replace fuse with rated value, never bridge defective fuses. Before changing fuse disconnect power cable from unit! To avoid deformation, discoloration, or other serious damage, do not expose this unit to any of the following conditions:

  • Direct sunlight
  • Strong magnetic fields
  • Excessively dusty or dirty environments
  • Strong vibration or shock
  • Heat sources
  • Extreme temperature

  1. Input Jack: Accepts 6.35 mm (1/4″) audio jacks for connecting active or passive basses. If you use effects pedals, connect the output from the last unit in the signal chain here. We recommend using high-quality instrument cables for the best sonic performance and reliable connection.
  2. Signal LED: The LED will light up green when the instrument signal passes the preamp without any compression. Higher input levels and gain settings will activate the built-in compressor/limiter to prevent clipping in the pre-amp stage. The LED will light up red to indicate active compression. The compressor also tracks changes made to the EQ settings, therefore an increase in an EQ setting might require a decrease in the Gain setting to maintain the same amount of compression.
  3. Gain: Adjusts the input gain of the pre-amp stage.
  4. 3-Band EQ: The active tone control EQ section provides up to +/- 15 dB cut or boosts for each band. All controls set to the center position (12 o‘clock) will provide a flat EQ, turning the knobs clockwise will boost the frequency band, and turning the controls counterclockwise will cut the frequency band.
  5. Master: The master volume control sets the signal level for the power output stage and the speaker output on the back of the Gnome amplifier. Set Master completely counterclockwise before you turn on the amplifier and increase the control slowly until you reach the desired volume level. A built-in limiter will prevent power amplifier clipping when maximum power is detected.
  6. Power LED: The LED will light up green when the Gnome is powered and turned on.
  7. AUX Input: Input to connect external sound sources, accepts 3.5 mm (1/8″) stereo jack for connecting (Gnome I Pro V2).
  8. Headphone Jack: Accepts headphones with 6.35 mm (1/4″) audio jacks. Silent practicing is possible if you disconnect the speaker output and input your headphones. Silent practice without a connected load will not cause any damage to the amplifier

  1. Power Switch: This switch turns the Gnome amplifier on and off. Connect the power cord from the mains outlet to the amplifier before you turn this switch on. To disconnect the amplifier, turn the switch off first, then disconnect the power cord from the outlet, and finally disconnect the power cord from the amp.
  2. AC Mains In: This is the power socket for an IEC line cord, which provides AC power to the unit. Always make sure to check the line voltage marking on the unit before you connect the power cord. Improper line voltage may cause serious damage to the unit.
  3. Speaker Out: Accepts 6.35 mm (1/4″) mono jacks to connect an external speaker cabinet. The minimum load for the amplifier is 4 ohms.
  4. XLR DI Out: Low impedance balanced XLR output for connecting the amplifier to a stage box, mixing desk or the PA for live and studio use. The XLR DI out is configured post-EQ with standard wiring (Pin 1: Ground, Pin 2: Signal +, Pin 3: Signal -).
  5. Ground Lift: The switch will disconnect the ground connection from pin 1 on the DI output XLR socket. Use this function only when you face excessive hum, possibly caused by a ground loop. Usually this switch should be left in the out position.
  6. USB Out Port (only on Gnome i and Gnome i Pro V2): Connect the USB type B port to PC, MAC or compatible mobile devices to use the audio interface.

Setup & Operation

To use your new Warwick Gnome amplifier, follow the quick start instructions:

  1. Unpacking: Unpack the amplifier carefully from the box.
  2. Powering up: Ensure the Power Switch is in ‚off‘ position, then connect the supplied power cord from the AC Mains In of the amplifier to the main power outlet. Now flip the power switch on the amplifier to the ‚on‘ position.
  3. Connecting speaker cabinets: Connect speaker cabinet(s) to the Speaker Out using a compatible speaker cable. The recommended the minimum load for the amplifier is 4 ohms.
  4. Connecting an instrument: Turn the Gain and Master controls to a minimum, then connect your bass to the Input Jack on the front pan
  5. Adjust Gain for a good input level, set the EQ controls as you like, and adjust the Master volume to a reasonable level.
  6. Start playing!

USB Interface (only Gnome i and Gnome i Pro V2)
The Warwick Gnome i and Gnome i Pro V2 amplifiers feature a USB audio interface that can be used as a universal connection device for PC, MAC or compatible mobile devices without any specific drivers or software requirements. The interface uses high-quality ADC/DAC converters to convert your audio signal to be processed with the many applications available or for direct recording in your DAW. Gnome i and Gnome i Pro V2 are functioning as external soundcards for your mobile device or PC/Mac, converting your instrument’s signal into a digital audio signal. The interface section is compatible with any USB device that can manage digital audio signals, via a standard USB-B to USB-A cable.

Setup a Windows 7 / 8 / 8.1 / 10 Device

  1. Use a USB-B to USB-A cable to connect the amplifier to your computer.
  2. Your computer will recognize the interface automatically and set all parameters accordingly. If you have problems with the automatic setup, open the sound settings (right-click on the Windows Start button > Control Panel > Sound).

  3. Under the Output tab, select USB AUDIO CODEC as your default device.
  4. Under the Input tab, select USB AUDIO CODEC as your default device.
  5. Close the window.

Protective Circuits
Your new Warwick Gnome amplifier comes with multiple protective circuits to prevent malfunctions under unsuitable operating conditions.

Over-Current / Short-Circuit Protection
The amplifier features an over-current / short-circuit-protected output. A current drop occurs when the amplifier exceeds the specified peak current output. This goes along with the drop in the voltage of the amplifier. If the current output of the amplifier exceeds its specified peak current output for a longer period of time e.g. in case of a short circuit of the output, the amplifier will be disabled (muted) for 1000 ms and automatically restart.

DC Output Protection
A built-in DC protection circuit will attenuate any DC signals on the power amplifier input, produced by a signal containing a DC signal. In case of a permanent DC on the output of the amplifier, the amplifier will latch and power must be removed for the product to restart.

Excessive Temperature
This circuit protects the power stage from malfunction by switching the device off if the temperature-regulated fan cooling proves to be insufficient and the temperature of the unit is too high.
