Power Safety

• This apparatus is supplied with a universal power supply, approved and certified for operation in this apparatus. There are no user-replaceable fuses.

• A power cord is supplied with this unit. Alternative power cords may be used if rated 2.5A or above and fitted with a 3-pin IEC320 connector.

• Use only the Solid State Logic provided power supply. Use of any other power supply is not covered by your warranty and may cause fire or explosion.

• Any external power supply may become hot during normal operation of the unit. Use care when handling the power supply.

• Do not attempt to modify the power supply unit in any way.

• If an extension power cable or adaptor is used, ensure that the total power rating of the power cable and/or adaptor is not exceeded.

• The power socket used for this apparatus should be located nearby and be easily accessible.

• Unplug this apparatus during an electrical storm or when unused for long periods of time.

Installation Notes

• When installing this apparatus, place the apparatus on a secure level surface.

• Ensure that no strain is placed on the cables connecting to this apparatus. Ensure also that such cables are not placed where they can be stepped on, pulled or tripped over.

Using VHD

VHD – Variable Harmonic Drive™ – allows a signal (microphone or line) to be over driven from subtle harmonic colouration through to full on distortion. The level of the incoming signal will have an affect on the VHD circuit, as will the PAD button which offers 20db of gain reduction for loud signals, allowing the Alpha VHD Pre to work with line as well as microphone level signals.

Each Alpha VHD Pre input features a control labelled ‘VHD’ with a range of adjustment indicated as ‘2 Adjusting the VHD control changes the character of the added distortion from predominately 2 entirely 3 The character of 2 harmonic distortion is associated with the harder, brighter sound achieved from solid state devices.

The VHD control will have a far more noticeable effect at higher gain settings so the input gain should be used in combination with the VHD control to affect the amount of distortion being added to the input signal. The PAD button will glow red when the input stage is starting to overload; the VHD circuit is designed such that this is part of the normal operation, though this should be avoided for a cleaner signal.

An over driven pre-amp may obviously have an effect on the gain of all parts the signal chain which follow the unit and the output gain may need to be taken down to interface correctly with other equipment. The output level control makes this adjustment a simple process.
