INSTALLATION
01)
The amplifier is quite heavy. Consider the location carefully, and
use appropriate help in lifting, etc., so
as to avoid injury.
Ensure that it will not tip over in your use; if there is a risk of this, especially due to
children, take all necessary steps to secure the amplifier to a wall.
002) Install the vacuum tubes. Each tube or its box has a “V” number, which corresponds to the labels on the
top plate of the amplifier; these indicate where each tube should be installed.
Fit each tube into the matching socket.
When inserting and removing tubes, handle them by their bases, not by their glass bulbs.
Note that there is a locator ridge on the tubes’ center posts that indicates proper alignment.
03)
Place the top ventilation grill in place. It rests on the four button magnets attached to the side rails.
04)
Set the back panel switch to Balanced (for use with balanced sources on XLR connector) or Single-
ended (via RCA connector) as desired. Balanced input is preferred. Note: if operating in the mono
mode with RCA inputs, use the upper (“left”) RCA input.
05)
Set the three Mono/Stereo switches to the desired mode of operation.
06)
Install the input cables in the back panel jacks that corresponds to the switch settings selected above.
07)
Connect the speaker cables; the black lead goes to “-“ or “Ground”. The red lead goes to “+” or
“Positive”. There are binding post pairs for left and right in stereo operation, and another for mono.
08)
Connect 12 volt trigger input cables into the appropriate sockets on the back panel if desired; either will
slave the off/on function to the external connection.
09)
Provide adequate ventilation - allow at least six inches above and three inches to each side, and front
and back.
10)
Do not place in a completely enclosed cabinet.
11)
Do not operate on any surface that might block air flow.
12)
The chassis and glass will become hot in normal use.
13)
The power supply may produce a small mechanical hum; therefore avoid placing the system on any
surface that could act as a sounding board, or at any location in the room that corresponds to a
resonance at your local power frequency (50 Hz or 60 Hz).
14)
Do not allow the chassis to touch any metal parts, such as the frame of an equipment rack. This might
