Mtroniks digiSOUND 602 User manual

Introduction.
Congratulations on the purchase of your Mtroniks locomotive sound module.
Throughout the design process we have striven to make the digiSOUND sound module easy to use whilst at the same time
offering as realistic a sound as possible.
The sounds reproduced by the digiSOUND sound modules are sampled from actual locomotives, they are not synthesized
sounds. This is what allows the digiSOUND602 to produce such realistic sounds.

Installation.
Your digiSOUND sound module should be mounted to a metal section of your model locomotive which will act as a heatsink for the
internal amplifier.
Once mounted in your model connect one or two speakers to the speaker outputs.
Next, connect the signal cable to your motor positive and negative terminals (either way round).
The next connection is the 12.0V connection from your battery supply.
If you are using 24.0V (2 x 12.0V batteries in series) you must connect to the one at the negative side. ie. the side supplying the
negative to the speed control system.
Referring to the picture, the other connections allow triggering of the engine start, run, stop sounds and the activation of the horn
sounds.
Linking the wire pairs activates the sounds.
The engine start, run, stop wires can be momentarily opened and closed to activate the partial MUTE function. This lowers the
volume and is useful when entering stations. Momentarily opening and closing the connection returns the system to the full pre-set
volume you adjusted on the main volume control.
These connections must be made by ISOLATED switches or relay contacts, NOT by connections directly on a speed controller,
this can damage the sound system.
If you have an Mtroniks speed control system these connections can be made via the relay board so that the button and switches
on the speed control handset fully control the operation of the sound module.

Notes on speaker
performance.
The speaker included
with your module will
depend on its power
output, however, you
should always install your
speaker into a suitable
enclosure to ensure the
best power handling and
frequency response.
If you intend to use a
tweeter for extended high
frequency sounds you
need to install a special
coil component to make
the tweeter compatible
with the class-D amplifier
in the digiSOUND602
module.

Connection of ACI/DCI Solid State Relay board
The above diagrams show the types of solid state relay board's 4 channels, control connector and positive battery
terminal.
Each channel is controlled by one of the auxiliary switches on the ACI/DCI's handset, each has a current carrying
capacity of 20A.
The relays are solid state, they have no moving parts. When connecting the contact it can either be used to switch
the positive feed or be placed in the negative, but be sure that the negative (-ve) terminal is always ‘most’ negative.
If switching an inductive load, a coil motor or relay etc, then always install a diode across the coil.
The cable from the ACI/DCI unit with the 6-way connector, plugs into the connector on the relay board
Ensure all cabling is capable of carrying the currents concerned safely. Check connections are sound and correct.
Double check all connections prior to powering-up. Appropriately fuse all feeds from battery positive. If an accessory
requires only 12V, then where instructed above to connect a channel's common terminal to 24v, obviously that
terminal should be connected only to 12v (the centre point of the two batteries in a 24v system).
NB, The centre point should ALWAYS be permanently hard wired. NO SWITCHES OR CIRCUIT BREAKERS. The
power on/off for the model, and its fuse should ONLY EVER be in the POSITIVE battery wire as close to the battery
as possible.
