Page 2: Introduction
10 years ago. These advances have been achieved through the application of the latest technological developments as they become available and affordable. OCTAVE has specialized in tube amplification for the past 30 years, during which time we have developed a number of innovative technologies that have earned us a reputation as one of the leaders in the field. -

Page 5: Description Re 320
– including catastrophic power tube failure. The RE 320 is based on the stable and reliable SE technology of the MRE220 model, while incorporating the benefits of the recently- developed KT150 power tube. - Page 6 After 10 minutes without receiving signal, the RE 320 Ecomode is activated, turning down the power. In this “sleep” mode, the RE 320 draws only 20 W Idle current. Therefore, the unit produces no heat while it remains switched on.

Page 11: Checking The Tubes - Setting The Bias
Check that the Input switch (2) on the front is in the right position (RCA or XLR). Switch on the RE 320 using the on/off switch and wait a few minutes until the unit is powered. Now you can listen to music. -
Page 12: Operation
On the Muting function NOTE: The RE 320 is equipped with a Soft-Start circuit and a Power-Up delay timer. The amplifier is ready for use after a delay of approximately 2 minutes. Because there are no relays in the signal path, a low-level, slightly distorted signal from your source equipment may be heard through your loudspeakers during warm-up. -

The (Super) Black Box is an outboard power supply capacitance Black-Box-Connector upgrade for the power amplifier section (see chapter 8). You have to switch off the RE 320 using the power switch before connecting and disconnecting the Black Box! - Page 14 5. CONNECTIONS 5.1.

Page 15: Advanced Functions
The Power Selector allows adjusting the RE 320 in accordance to the output tubes. Position HIGH is reserved for the standard KT 150 or KT 120 tubes. In the HIGH Position the RE 320 is able to deliver up to 200 W RMS Output Power. The slightly weaker tubes type KT 88 or 6550 can be used in the position LOW. -
Page 16: Electronic Protection System
The BIAS LEDs will show "yellow" for each of the four output tubes. If a Black Box or a Super Black Box is connected to the RE 320, the front panel (operate) LED of the Black Box / Super Black Box will go out. If the Super Black Box is connected, tripping the protection system will automatically activate the discharge circuit of the Super Black Box (see chapter 8.2). -
Page 17: Ecomode (Power Saving Mode)
Note: If you switch the RE 320 on with Ecomode active, it will go through the start procedure. If it fails to detect a music signal, it will shut down after 10 minutes. Ecomode is not the same as standby, however, because certain sections of the amplifier remain on. -

7. TUBES 7.1. Removing the grille Operating the amplifier without its protective grille is dangerous and not recommended. To remove the grille: For your own safety, switch the amplifier off using the on/off switch or disconnect the power cord. Pull the grille upward to remove. See chapter 3.2. -
Page 19: Bias Measurement Electronic
That is why we have built this BIAS measurement electronic into the RE 320 – to allow you, the user, to carry out the adjustment yourself without the need for test equipment. The use of precision op amps makes it possible for you to set the BIAS to accuracy within 0.2%, making it superior to any... -
Page 20: How To Set The Bias
7. TUBES 7.3.1 How to set the BIAS Make sure that no signal is playing through the amplifier when you are adjusting the BIAS. It is sufficient to switch on the Muting function; there is no need to disconnect the speakers. The tubes should have reached operating temperature. -

7. TUBES 7.3.2 LED graphs, advanced adjustments of the BIAS setting There is an upper adjustment limit to the "high" BIAS setting, which is indicated by the green and red LEDs lighting up at the same time, and a lower limit to the "low setting, where the yellow and green LEDs light up. -
Page 22: Replacing The Tubes
7.5. Running in All OCTAVE equipment is subject to a 48-hour performance test at the factory to break in the tubes. The tubes are preselected for use in each particular model. New tubes can take up to three months to run in and start sounding their best. -
Page 23: Option Black Box And Super Black Box
With the Black Box technology OCTAVE offers an instrument for optimizing the OCTAVE amplifier in respect to the speaker. This flexibility is a unique feature of the OCTAVE brand. The dynamic and tonal stability of an amplifier is strongly dependent upon the stability and capacity of the power supply, therefore the Black Box and Super Black Box were developed as external upgrades to the OCTAVE amplifiers’... -

Yellow unload LED imately two seconds after switch-off, in case the electronic protection is activated and if the RE 320 is powered down through the Ecomode. The Super Black Box is equipped with a rapid discharge circuit, which discharges the unit’s electrolytics. The yellow LED indicates that that this procedure is taking place. -

PCs with sound cards, and some CD/DVD players and DACs. Although the RE 320 is grounded, its signal ground is a "floating" ground, which means that the RE 320 cannot create ground loops itself. Hum can only be caused when the RE320 is connected to other earthed units of the equipment. -
Page 26: Mains Interference
To reduce this kind of interference, move the transformer/component or the affected component/cable to a different location. The transformer in the RE 320 will not generate interference, as it is electromagnetically shielded and has a very low stray field. ... -
Page 27: Faults Caused By Tubes
9.2. Faults caused by tubes, faulty tubes Like other OCTAVE products, the RE 320 is equipped with a double safety system. This means that the amplifier will be protected from damage if a component (tube) should fail and trip the electronic protection. -
Page 28: Tube Faults That Trip The Protection System
This kind of noise does not often reach a level that could be considered annoying, although the nearer to the "front" the particular tube is, the more it will tend to make itself felt. In the RE 320, this would be tube V 6. As it is rare for both systems in a double triode to be equally affected, the noise levels in each stereo channel will be different. -

Page 32: Frequently Asked Questions (Faq)
Does the RE 320 have to have all of its tubes fitted? In principle, the RE 320 will also operate without tubes. It is sometimes useful to do this when testing the operation of the switching functions such as the selector switch, remote control, etc. - Page 34 We reserve the right to alter and improve the specifications in pursuit of better.
