I. FOREWORD 1. CONGRATULATIONS! You just have purchased the VP100 Reference preamplifier. VENTURE AUDIO first wants to thank you for your trust. The best components were selected for its realization, as an extreme care was provided during its manufacturing. These attentions will permit to reach true musical quality heights. VP100 Reference is the result of many years of studies and research, of much experimentation, and of many careful listening sessions.
3. VP100 REFERENCE VENTURE AUDIO continues its research and now proposes its brand new amplifier, VP100 Reference. Its commuted resistors design and its fully Single-End discrete buffer allow obtaining a really more natural restitution, through a transparence and dynamic never reached at present times. Its multiple power-supplies are fully independent and are set in an external cabinet, for a better magnetic isolation.
III. OVERVIEW 1. UNPACKING Your package contains: ) A VP100 Reference preamplifier. ) A Rc5 remote control, delivered with two Lr03 batteries (type AAA). ) An external power-supply unit ) A 12-pins power cord to plug between the preamplifier and the power-supply unit ) A mains power cord ) This user manual. 2. POSITIONING Your VP100 Reference preamplifier must be installed in a place far from about 10cm from the other appliances. This will guarantee the best signal-to-noise ratio.

V. OPERATION INSTRUCTIONS 1. POWER SWITCH After having connected the different inputs to the corresponding appliances (CD player, tape, tuner...) and the outputs to the dedicated appliances (amplifiers, crossovers…), the VP100 Reference preamplifier can be switched on using the power switch located on the rear panel. It is advised not to switch off the VP100 Reference, to fully and instantly benefit from its maximum musical quality.
3. PHONO SECTION (RIAA MM/MC) The VP100 has an adaptive (active) input load. There is no need for users to adjust the resistance input according to the cell they use (as they used to do thanks to MC input resistors matrix). Just plug your turntable to the right RCA (be it MM or MC depending on your appliance) and enjoy the music. This is safe, this is easy, and this will sound perfectly to the taste of your cell.
4. OPERATIONS Stand-By mode is accessible from the remote control. It allows reducing dramatically the energy consumption of the appliance. Once awoken (disabling the stand-by mode), the preamplifier will provide its optimum musical quality after only 15 minutes, whereas the first operation will require more than 4 hours of warm-up (as will require any main switch-on) to reach this same level. VP100 Reference offers 10 inputs (4 unbalanced “RCA”, and 4 balanced “XLR”, 1 Phono MM, 1 Phono MC).
5. DISPLAYS DESCRIPTIONS Standard display at start-up After start-up, the display shows the volume (attenuation level) of -66dB, and the first input is activated (RCA) The volume can be modified through remote control or the dedicated front knob, from –65dB (low volume) to 0dB (loud). By using the remote control or selection knob, the different inputs can be selected: RCA1, XLR2, RCA3, XLR4, RCA5, XLR6, RCA7, XLR8, MM and MC.
By turning left the Volume knob, the phase is decreased by steps of 10° down to -180° (minimum). Last in the set-up program, we can teach the preamplifier some new remote control codes. This functionality is only to be used when using a new remote control. This option is defaulted to OFF (disabled). Turn the volume knob right to enable it. Turning left sets it back to OFF. LEARN RC5 ERROR To use this functionality, select ON then exit the set-up. The screen displays LEARN RC5 ERROR.
6. SECURITY VENTURE AUDIO appliances are designed to operate in a perfect reliable and durable condition. This operation can however be influenced by external events. Some of them will require the action of the inner VP100 Reference security system. This security system aims at protecting the appliance from any over-voltage, for instance, as they also act to protect the whole Hi-Fi elements under the preamplifier « responsibility ».
7. CLEANING VP100 Reference preamplifier was designed to operate perfectly with no specific setting or maintenance for a large number of years. In case of dust removal, plainly process using a clean dry rag. In case of a dirty mark, DO NOT uses any detergent or solvent, but uses a clean wet rag. Caution: NEVER clean any appliance while in operation.

VIII. QUESTIONS AND ANSWERS What difference is there between VENTURE and standard stand-by mode? VENTURE stand-by mode does not switch off fully the appliance. Only the power stages are shut-off. They are the main current consumers. The heart of the amplifier stays warm and operational. This allows getting the full musical quality back in about 10 to 15 minutes after waking the appliance back up. A standard switch-on of the appliance requires about 8 hours getting that same level back.
What specific handling instructions are there for VENTURE appliances? See “Operation instructions”. Please note however, that it is always safe to switch off and unplug all mains cables before handling any cable from the system, being interconnects mains, speakers, or digital. This caution is not specific to VENTURE products. Also, please allow 30 seconds (mainly to the power appliances) before unplugging the cables. This will let the capacitors to empty themselves smoothly (no spark effect).
What are the security system-call causes? See security chapter for more explanations. Cause Over-tension (mains provider) External fuse Internal relay X Comment / solution Rare. Change the fuse. Unplug and switch back on. DC offset X (front LED : Red/ON) Generally comes out source elements such as CD players. Unplug all. Switch the appliance back on. It must operate perfectly alone. In that case, have your faulty element fixed/repaired accordingly.
