GOLDMUND dealer for internal adjustment. ATTENTION On the 220V configuration, the GOLDMUND TELOS 500 amplifier will function properly for main line voltage between 211V and 257V. On the 110V configuration, the main line must deliver between 105 and 129V. If your main line is usually out of these tolerances, please consult your GOLDMUND dealer. -
Page 8: Connections
Connect the speaker cable to the red and black terminals in the back of the amplifier, or, if you use a Goldmund High Definition speaker cable, you can connect directly from the speaker cable to the coaxial plugs on the back panel of the amplifier, bypassing the amplifier adapter module of the speaker cable. -
Page 9: Amplifier Controls
As soon as the amplifier is connected to AC line and the amplifier has not detected an error previously, the yellow light on the amp front panel is ON. The TELOS 500 may be powered on either manually (Manual Operation) or automatically when receiving a signal (Auto-Power Operation). This is selected internally by the small white 10-position circular selector located on the top circuit of the amplifier, close to the big capacitors. - Page 10 AMPLIFIER CONTROLS (Ctd.) MANUAL OPERATION On the front plate of the GOLDMUND TELOS 500 amplifier you will find only two POWER keys. In the Manual Operation mode, the two POWER keys have to be activated simultaneously to power the amplifier on.
- Page 11 OTHER DISPLAY If an abnormal situation is found by the TELOS 500, one of the front panel red lights may turn ON, and the power of the amplifier is instantaneously set OFF.

Page 14: Safety Features
(often true for the tube preamplifiers), the speakers could be damaged. In such a case, the DC protection circuit of the TELOS 500 will automatically turn off the amplifier. This detection circuit is totally immune to any sonic effect. - Page 15 If for any reason (malfunction, too high level, too low load impedance) the temperature of the amplifier could reach a dangerous level, the TELOS 500 could be damaged. To avoid this type of damage, if the temperature rises too high, a protection circuit switches the amplifier OFF automatically.
