Thanks to their unique output stage design, they will main- tain their optimum sound quality with virtually any amplifier. OCTAVE employs the latest electronic circuit designs to create the best possible Control + operating conditions for the tubes, and thus for the amplifier itself.
– without the need for corrective mechanisms. Whether the source equipment is connected via the RCA / CINCH phono or XLR inputs, the Jubilee tube preamp always produces a perfectly balanced output signal and delivers an optimum sonic per- formance independent of the source type.
Defective fuses should also only be replaced by a qualified technician. Always replace fuses with ones of the same type and rating. If your amplifier re- quires servicing, please ship or take your equipment directly to OCTAVE or to one of our authorized service centers.
2.2. Placement Location OCTAVE equipment is designed strictly for use in a dry domestic environment with a room temper- ature up to 25°C. Do not use it in open air or in damp environments! Never place plants or liquid-filled containers on your amplifier. Take care that objects do not fall or liquids are not spilled into the enclosure.
5. Turn the volume control anticlockwise close to the minimum setting. Remember that high sound pressure levels can damage to your hearing as well as your loudspeakers. 6. Connect the power supply to the wall socket. Plug the power cord [24] of the Jubilee power supply into the special socket on the preamplifier. [19]...
Switch the power supply on (switch [26]. LED [25] on the front panel of the power supply will illumi- nate. Wait until the Muting LED [1] on the Jubilee preamplifier goes out. The unit will be ready for use in about four minutes.
4. OPERATION 4.1 JUBILEE PREAMPLIFIER FRONT PANEL The Jubilee preamplifier is equipped with a delay timer function that helps conserve tube life. The output is muted (muting LED illuminates) for four minutes during the start phase The muting function is also activated when the gain switch [4] is used (See Sec. 3.2.)
4. OPERATION 4.2 JUBILEE PREAMPLIFIER TOP VIEW Legend GAIN Facility for switching between high (H) and low (L) gain. The appropriate LED illuminates to show which position is active. H (HIGH) position: This is the standard position for the majority of power amplifiers and loudspeakers.
5. CONNECTIONS 5.1 REAR PANEL JUBILEE PREAMPLIFIER General points: The following applies to all connections: L: LEFT channel, R: RIGHT channel XLR pin : 1: GROUND, 2: + 3: - Legend RC: Connector for the infrared receiver.

5. CONNECTIONS 5.1 REAR PANEL JUBILEE PREAMPLIFIER Legend Phono preamp inputs (RCA/CINCH) These inputs are active in the PHONO INPUT MODE ASYM setting. The RCA / CINCH inputs are wired in parallel to the balanced (XLR) inputs. You can use either the RCA / CINCH or the XLR sockets to connect a phono preamp.
Before connecting the mains power cord into the wall socket, make sure that your amplifier is suitable for your local supply voltage. To exclude the risk of electric malfunction, connect the power supply with the Jubilee preamp before you connect the power supply to the mains. Fuse holder Warning: Fuses should be changed only by a qualified technician.
6. REMOTE CONTROL FOR VOLUME 6.1. REMOTE CONTROL TRANSMITTER + Volume up - Volume down Changing the batteries Procedure Take off the bottom plate (three screws size Phillips 1) Change the batteries: 2 x Type AAA 1.5 V alkali-manganese / alkaline) Please take care not to push the buttons of the remote control while inserting the new bat- teries.
Connector to Receiver the rear panel Because it would not be very aesthetic to drill a hole in the Jubilee front panel, we decided to use a solution with an external receiver Procedure Connect the receiver with the plug on the rear panel...
7. TUBES 7.1 TUBE LAYOUT Tube replacement should be done by a technician. Before opening the cover it is mandatory to remove the power cord from the mains power inlet. Tubes used also available under this description ECC 82 (E82CC, ECC802S, 12AU7, 5814, 6189W) Sockets [29] and [30] require selected, matched tubes with equal systems.
Switch off the preamplifier, unplug the power cord from the wall socket and allow the unit 10 minutes to cool down The Jubilee's automatic discharge system will discharge the power supply capacitors. The red LED [31] will be lit during this time (see Tube Layout, Section 6.1). To avoid an electric shock, wait until this LED has extinguished before opening the case.

9. TROUBLESHOOTING Cracking noises when switching on and off POSSIBLE CAUSES Household electrical equipment such as older refrigerators or 12-volt halogen light- ing systems can generate strong radio interference when they switch on and off. This electrical interference can cause an audible crack or pop through the speakers. REMEDY Connect your hi-fi system to a central mains distribution board plugged into a wall socket.
