Volume Controls:
A pair of small trimpots on the
Sd-25
are
used to set the maximum audio output level
from the Sd card. The operating modes
which ramp the audio up and down can
never exceed the level set by these pots.
An additional pair of pots is used to set the
levels for the ‘mixer’ inputs.
You can adjust these pots using a small
‘trimmer’ screwdriver. A suitable screwdriver
comes as part of the
.
These trimpots are smaller than you. Do not
use a big screwdriver on them. Do not apply
too much force.
They can be broken if you
strong-arm them!

Line Level Inputs and Outputs:
Two gold plated
‘RCA’ jacks are

A switch on the
b o t t o m o f t h e
case allows you
to switch these
jacks between a
line level output of the audio coming from the
Sd card, or a line level input that gets mixed
with the audio coming from the Sd card.
When the switch is set to the ‘Line Out’
position, the audio from the Sd Card is sent
to both the amplifier and the RCA jacks. Only
the audio going to the amplifier is routed
through the ‘Sd Level’ pots. The RCA
outputs will always be at full volume unless
the audio level is reduced in the DSP by a
serial volume command, DMX-512 volume
command, or full or half muting command
from the trigger inputs.
To use the line level outputs, just run a pair
of RCA cables to your amplifier (or amplified
speakers), just as you would if you were
connecting an iPod or CD player. The line
level outputs are robust enough to drive
headphones and small speakers directly.
When the switch is set to the ‘Line In’
position, line level audio signal from a
