Impedance Matching
The available impedance settings on your Heros are:
- 8 ohms – use for speakers rated 6 to 16 ohms
- 4 ohms - use for speakers rated 2 to 6 ohms
Since the impedance of most loudspeakers vary over a wide range experimentation is
essential. Most speakers have a rated impedance of 4 or 8 ohms. We recommend
starting with the 8 ohm connection; after you know the sound if that connection, try the 4
ohm connection. Choose the connection that sounds best to your ears.
Tube replacement
Your Heros comes with the tube pre-installed. Tube's working time is approximately 2 000
hours. When tubes replacement is due, we strongly advise you to order replacement
tubes from your Thrax Audio dealers, before the sound quality starts to deteriorate.
Before replacing the tube, all power must be turned off. Unplug the power cord from the
wall, and remove all audio interconnect cables. Wait 15 minutes before removing the
tube .
When removing the tube, handle it carefully, whit minimum twists.
Install the new tube firmly in the socket, noting the location of holes in the socket and pins
of the tube, taking care to make sure that pin pattern corresponds to holes in tube socket.
