Advantage: No losses of tone due to splitting the signal at the “thru” jack
It is a midi programmable tuning loop.
To program: Select a midi patch at your foot controller. channel 2 on - insert on - push
“Store” twice - done.
Channel insert 3 and 4 allow you to use other diverse tone shaping devices, like noise
gates, eq, etc. Remember that the effects units that are assigned to the channel inserts
will only work for the selected channels that they are connected to. Also, the “feel” of the
effects units will be different due to the higher signal voltage to the input of the effects
unit.
3.4 Speaker Connections
As a rule, the impedance of the loudspeaker to be connected should match the
designation of the output jacks that it is connected to. We suggest using speakers that
have an impedance range of 4Ω to 16Ω, as singular speakers or in combinations.
Do not ever run the VH4/VH4S without having speakers connected to the output jack (
both sides of the VH4S).
Danger of Amplifier damage.
ΩΩΩΩΩ’s
If you are using 2 ea. 16Ω speakers, then the total impedance is 8Ω. Really -trust us on
that. 2ea. 8Ω speakers make 4Ω. This is because the speaker jacks on the amp are wired
in parallel mode. Your local library has many books on Ohm’s law.........
3.4.1 Choosing Speaker Cabinets
Oh boy. This is one big subjectivetug-o-war. Every manufacturer has it’s own philosophy,
even though most cabinets are constructed surprisingly similar.
The influences of magnets, coils, box volume, open or closed backs etc, all this has a
certain influence on the ultimate way the cabinet will respond to amplifier input at
different levels.The rule is that if you like the way it sounds and if it matches the amp,
then its a good choice. Make sure the combined impedance is no less than the amplifiers
minimal requirements.
Test your speakers at realistic volumes, as if you would play them most often. Many
cabinets sound very different at higher volumes than at low volumes like in a music store.
Ultimately this speaker will have the last word in at what you are going to sound like.
Many cabinets swallow the all important midrange of your tone spectrum due to internal
cancellations, which is often caused by a vibrating rear speaker cabinet wall.
We have designed a speaker cabinet that matches the Diezel VH4 series amplifier quite
well. It is the Diezel V212/V412 speaker. The cabinets are Mono/Stereo wired and utilize
Celestion Vintage 30 Speakers, or your choice of speakers on a special order basis. These
cabinets are constructed by hand, from choice hardwoods and with very good tolerances
and internal bracing. They make an excellent all round speaker and can cover a wide
array of styles. Of course, the VH4 amplifier will also work with other brands of cabinets,
including your own favorite.
