Page 7: The Earth / Grounding Concept
The Earth / Grounding Concept General GROUND-LIFT Jumper (accessible from the inside. Mind the SECURITY INSTRUCTIONS !! ): Ex-works this jumper is set to the LIFT position. The internal ground potential is “lifted” by means of this jumper. As a result, the interconnection for DC voltages and lower frequencies (<... - Page 8 Unfortunately there is no general recommendation how to solve hum and jitter problems - or even minimize them. The best way to succeed is to check different options !! In case of balanced cables, it should always been verified if the shield of the cable is connected to the shell of the XLR connector.

GENERAL The PRE V630 is a high-quality, two-channel preamplifier for line level signals. It offers 3 unbalanced stereo inputs, a high performance volume control and balanced as well as unbalanced stereo outputs. The maximum output level can be adapted internally in many ways, additionally the unbalanced output can be set for pre- or post fader operation. -
Page 11: Power Supply
THE CASE The PRE V630's case as well as the front/rear panels are made of solid aluminium. This choice of material ensures high mechanical stability and resistance. EARTH AND GROUND The PRE V630's case is grounded. Internal reference ground is bridged to protective earth by means of a jumper. -
Page 12: Unbalanced Inputs
UNBALANCED INPUTS For the use with unbalanced signals, gold plated cinch sockets are provided. They are labelled in the field "ANALOG INPUTS" as "L/R” and "1 / 2 / 3". Here, unbalanced sources with a level of up to +24 dBu may be connected. -
Page 13: Input Selection
INPUT SELECTION The activating of an input is internally made by means of relais. This process is controlled by the front mounted buttons labled "SOURCE SELECT 1 / 2 / 3 ". The activated input is shown by the corresponding yellow LED, marked with "1 / 2 / 3". - Page 14 At last the signal reaches the output drivers which may be set to different output levels. THE UNBALANCED OUTPUTS are situated on the rear panel of PRE V630 in the field "ANALOG OUTPUTS " and denoted as "UNBAL L/R". They are equipped with gold plated cinch sockets.
- Page 15 Ex works the unbalanced outputs are set to “Post Fader” state. The output level from the unbalanced outputs may be set to –6 / 0 / +6 dB by means of the dedicated dip switches. This ratios is relative to the input signal and fully open volume control.

Page 16: Opening The Case / Dismantling
DISMANTLING / JUMPER SETTINGs In order to change any DIP switch or jumper settings inside the PRE V630, its case must be opened. For this purpose, a TORX screwdriver T10 or 3mm allen key is required, and you should - by all means - PULL THE MAINS PLUG !!! after which any setting procedures can be effected without risk. -

WARRENTY Since 1986 we are constructing and manufacturing sophisticated electronics for ambitious customers. Since the early beginnings we are trying hard by accompanying measures, the use of 1st choice components and multiple quality checks during production to avoid faults at large. We are quiet effective in that and this is - amongst others - why we enjoy such a good reputation.
