MOSEL VITELIC
MSS0306
8 ohm speaker is recommended. The speaker charac-
eristics and housing impacts the loudness very much.
When user is using variable loudness, user must care-
fully calculate the bypass resistance and transistor's
beta value due to that the current from Cout may vary
very much due to user's specified loudness variance.
Terms
Retriggerable TG
Retriggerable TGm means the sentence addressed by
TGm could be retriggerred by other TGs.
See Timing diagrams. Of course, it can be retriggered
by itself. See Timing diagrams II.
Hold and Retrigger
This combination allows user controlling both the output
and the input. Its output is holdable and the input
could retrigger the former. This is an exquisite feature,
to ensure your application is fit to this feature or not
before being manufactured is recommended strongly.
Or the user may overshoot the mark and end up with a
blunder.
To contact MVI sales representatives is the best
solution for this feature.
Small Loop & Large Loop
This is a function belongs to OKY. OKY plays many
sentences, up to 32. User can play 1st sentence
through 32nd sentence if user selects "large loop". At
this time the sentence lst, 2nd, 3rd and 4th may be
triggerred by TGs.
User will play 16 sentences, from 17th through 32nd
sentence, when user selects "small loop".
User may have less sentences triggered by OKY at this
selection. But user definitely can prevent those OKY's
sentences triggerred by TGs.
Ring 3 Hz LED
Ring 3 Hz LED had better to mask 3 LED sink pins
together. But if user insists, two LED pins or one LED pin
could be used to perform this ring function.
LEDX and LEDY must be adopted to perform "Ring" if user
specifies 2 LEDs. Adopting LEDX and LEDZ is not
guaranteed the performance. Of course adopting LEDY
and LEDZ is not guaranteed, either.
LEDX must be adopted to perform "Ring" if user specifies
one LED. Neither adopting LEDY nor LEDZ can perform
guaranteed function.
Each LED turns on for 333 ms (1/3 second) and turns off
for 667 ms (2/3 second). LEDX turns on first. LEDY
turns on immediately after LEDX turns off. LEDZ turns on
immediately after LEDY turns off. LEDX turns on again
immediately after LEDZ turns off.
This 3Hz is sample rate dependent.
Ring 6 Hz LED
It performs what "Ring 3 Hz LED" works except the turn on
and off frequency. Each LED turns on for 1/6 second and
turns off for 2/6 seconds.
Ring 12 Hz LED
It performs what "Ring 3 Hz LED" works except the turn on
and off frequency. Each LED turns on for 1/12 second
and turns off for 2/12 seconds.
Fix flash LED
Fix 3 Hz flash means this pin turns LED lamp on for 166ms
and then turns it off for 166ms alternately. Fix 6 Hz flash
means quicker, it turns on 83 ms and then turns off 83 ms.
There are up to 3 LED sink pins could be manufactured as
user's mask specified. LEDX is synchronous with LEDZ.
LEDY shifts 180 degrees phase with LEDX. User can find
their timing relationships on timing diagram VI.
These 3Hz as well as 6Hz are sample rate dependent.
Cycle Loop
This is a count number ranges 1 through 32 which
defines the sentence range OKY will play. This number
is determined automatically by the sentences user filled,
user defined.
Continuous OKY & Home OKY
This is a function belongs to OKY and determines the
play sequence when the first OKY comes after any
other trigger addressing. The "continuous" preserves
the sequence while the "home"rewinds to the very
beginning. This very beginning means either 17th
sentence or 1st sentence which is determined by Loop
Size - small or large.
You will see a term S.W.A.I. in this data sheet, it means
sequence when after interrupt by other trigger
addressing.
Dynamic Flash LED
The LED turns on whenever the sound amplitude is over a
certain threshold potential. Three LEDs (X, Y and Z) have
different threshold. LEDX is the easiest to turn on. LEDY's
threshold is the highest. LEDX's is 4/8 of full scale output
current. LEDY's is 7/8 while LEDZ's is 6/8.
For example, A point (a sample pixel) of sound in volume
level 90% of full scale output current, it will turn on all three
LEDs. A point in 80% current will turn on LEDX as well
as LEDZ. A point in 70% current will turn on LEDX only.
A point in 49% current or less turns no LED on.
Initial high & Initial low
This is a function belongs to OUTs. It defines the state only
from power on to the first audio activated. It is effective
both for LED and Status.
"Initial low" means user want this OUT pin is put to low
