RECOMMENDATION RECOMMENDATION The following recommendations are to ensure that the device always functions reliably: Never open the casing! To do so would expose you to the risk of an electric shock. Should repairs prove necessary, leave them to qualified service personnel. Avoid dust and high moisture levels, direct sunlight and extremely high or low temperature. Safeguard the device from excessive vibration. Always place the unit on a stable and horizontal surface. See to adequate ventilation.
INTRODUCTION Welcome to the Warwick family and congratulations to the purchase of one of our fine Amps. The Jonas Hellborg Series of Bass amplification products is designed to be the highest quality system of amps specifically for bass available today. There is truly no musical challenge that will present a problem for this extraordinary range of products.
02 PREAMP
PREAMP The centre piece of the “Hellborg Amp System” is the Preamp. The input is a combined ¼”/XLR jack providing both low (XLR) and high (¼”) impedance. The input jack is followed by an input transformer. This imparts galvanic signal isolation and the sweetness for which good transformers are known. The EQ section provides shelving EQ for high and low band and an inductive (coil based) EQ for the mids with stepped (fixed) frequency and continuously variable gain.
GETTING STARTED QUICK START PREAMP 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 02 Make sure that the Power Amplifier load is matched to the connected loudspeakers load. We recommend using speaker cables with lockable coaxial connectors that meet a cross-section of at least 2 x 1.5 mm. Check that the mains supply has been plugged in and that the connection Pre- to Power- Amplifier is correct. Make sure that external (effects) units possibly used are correctly connected and operational.
PREAMP 4 1 2 3 5 6 7 8 9 10 11 12 Input Jack This Neutrik© Combo Connector provides an unbalanced ¼” and balanced XLR input. The ¼” jack is used for all normal basses. The balanced XLR input is for instruments with balanced outputs. 2. PAD Switch Some instruments have an unusual low output level. If you own such an instrument, it may be necessary to disengage the -20dB PAD to match the correct signal level with this Preamp. Note that the PAD should normally be engaged.
OPERATING INSTRUCTIONS PREAMP 1 1. 2. 3. 4. 5. 6. 02 2 3 4 5 6 IEC Socket and Fuse Holder This is the socket for plug in the line cord. The fuse tray contains the main fuse of the Preamp. Replace the fuse only with the same type and size. Voltage Selector Switch This switch is set at the factory to the correct voltage for your country. It can easily be changed to 230V or 115V by switching to the correct position. Fuse values are T500mAL for 230V and T1AL for 115V.

2/250W MONO POWER AMP 250W MONO POWER AMP 500W The Hellborg Power Amps again are a mix of old and new ideas. They are characterized by their capacities to deliver fast transient attacks due to over dimensioned output stage and by the warm tube like sound resulting from the large speaker output transformers. In addition it has a range of computer controlled safety features to keep both amps and speakers healthy and happy.

It can easily be changed to 230V or 115V by switching to the correct position. Fuse values are T5AL for 230V and T10AL for 115V.
MOUNTING OF THE POWER AMPLIFIERS FRONT MOUNTING REAR MOUNTING The Hellborg Amplifiers are designed for installation in a conventional 19” rack case. 2 brackets for securing the Power Amplifier and 4 case nuts and screws are supplied.
The new Warwick Jonas Hellborg Power Amplifiers are equipped with a series of circuits to prevent it from destruction in case of inadequate operating conditions: Power-up delay: When the unit is switched on, the SPEAKER OUT sockets are activated with a slight delay to protect the loudspeakers. Short-Circuit: In the event of a short-circuit at the Power Amp outputs, this feature prevents the output stage transistors from destruction by quickly reducing current.

04 CABINETS
The philosophy behind the cabinets is to through correct cabinet design and use of specifically designed speaker drivers create clear full and loud sounding bass cabinets that projects over large spaces.
CABINETS CABINETS Club Cab Big Cab Hi Cab Lo Cab The Club Cab is designed to be portable, full range and loud enough to deal with any small venue or club setting. It basically is the top half of the Big Cab, with the same specially designed Celestion coaxial 15-inch speaker inside. It outperforms any 4x10 cabinet in the realms attack and clarity and still has a big, warm bottom end. The Big Cab is a full range, high-performance speaker cabinet. It comes loaded with two Celestion 15-inch speakers.
