STEREO / MONAURAL OPERATION

To run the amplifier in Stereo, simply connect the left and right input jacks to your source or preamp and the left and right output binding posts to your speakers. If using the variable inputs, the volume control located at the front of the amplifier will control the output level of both channels at the same time.

To bridge the amplifier into a monoblock (single channel amp) all that is needed is a short piece of 14 AWG wire hooked between the Left nega- tive (black) speaker binding post and the Right positive (red) speaker binding post on the other side of the amp. This leaves two binding posts left, one on each side of the amp, to drive your loudspeaker.

This is made possible by the SE84ZS floating output transformer design where the negative speaker binding posts are not tied or referenced to ground (chassis). When you hook your amp up as described, you have effectively wired the output transformer in series creating a single mono circuit that does not have the typical smearing associated with bridging stereo ampli- fiers.

To hook up the inputs of the amplifier in mono so that only once cable is needed from the preamp or source it is recommended that you use a Y-Cable that plugs into the left and right input jacks combining them into one. Decware can supply you with high quality Y-Cables made from the same Silver/Teflon conductors as our signature cables. Alternately space has been provided in the design to accommodate a stereo/mono switch for the input jacks should someone wish to custom order the amplifiers that way. We should mention that our Y-Cable gives the same sonic results as the switch, costs about the same and keeps you from having to ship your amplifier back to Decware for the modification. That is one of the reasons why a stereo/mono switch is not standard on the SE84ZS.

HOW TO OPERATE

After finding an appropriate place for the amplifier you can install the tubes and con- nect the speaker cables. Do not hook up the input cables at this time. Install the power cord and plug it into a grounded receptacle and turn the amplifier on.

Let the amplifier warm up for several min- utes with the volume control all the way down. NOTE: it is common for new tubes to make an occasional spit or crackle upon startup. This goes away after the first cou- ple uses.

Now that the amp is on and warmed up for a few minutes with no source or preamp con- nected to it, it is your chance to evaluate the noise level of the amplifier. What you hear coming from the speakers is your baseline reference for a given set of tubes. All tubes will vary somewhat. On all but the most effi- cient loudspeakers, you should hear almost nothing at a distance of less then 1 foot from the speaker. Decware amps are known for being quiet.

Next, turn the amplifier off and let it cool for 1 minute. Now hook up your source or preamp making sure to have the volume control all the way down and turn the ampli- fier back on. Raise the volume control to your desired listening level and enjoy!

BURN-IN PROCESS

Expect less then wonderful sound for the first 20 to 40 hours of operation as the ca- pacitors break-in. The fastest way to ad- vance the burn in process is to play the amp for 5 hours and then turn it off for at least 5 hours. Repeat this at least 5 times. Most customers find that the amp really blooms in about the 3rd week of their evaluation.
