ESU 58751 LokSound 5 Micro Direct NMRA DCC Sound Decoder - N Drop-in Board for Pre-2016 Atlas Narrow Hood type

The LokSound 5 micro DCC Atlas Legacy is also a “direct style decoder developed for early (before 2016) Atlas, Intermountain (and others). The decoder was made for locos produced before sound was added during production. This replaces the popular ESU 73100 Select Direct Micro.

Both the LokSound 5 micro DCC Direct/Atlas Legacy with their dimensions of 66.0mm x 8.2mm are pure DCC decoders and come without a loudspeaker.

Modes

The LokSound 5 micro DCC Direct/Atlas Legacy are both “pure-bred” DCC decoders. 14 to 128 driving steps are as self-evident as 2- and 4-digit addresses. Up to 32 functions can be triggered. Thanks to RailComPlus®, the decoders log in fully automatically to a suitable digital center. It masters all DCC programming modes and thanks to RailCom® the CV values can be read out on the main track with suitable control panels. Auxiliary registers exist for control panels that can only program the CVs from 1-255.

The LokSound 5 micro DCC Direct/Atlas Legacy Decoders detect the Märklin® brake distances as well as ZIMO® HLU / ZACK commands or the Lenz® ABC system. Braking with DCC brake blocks or dc voltage is also possible. In addition, it also stops with a Selectrix® brake diode. An AUTOMATIC ABC commuter train allows automatic commuting between two stations.

The LokSound 5 micro DCC Direct/Atlas Legacy decoders can be used on analog DC layouts.

The decoders switch “on-the-fly” fully automatically between operating modes. Most of the time, nothing needs to be adjusted.

Sound

The LokSound 5 micro DCC Direct/Atlas Legacy decoders can play up to 12 channels simultaneously. Each channel can be resolved with up to 16 bits / 31250 kHz and offers hi-fi quality on your system. There is virtually no difference to the original audible anymore. A Class-D audio output stage with up to 3W output power controls the speakers, which have between 4 ohms and 32 ohms impedance. A 128 Mbit sound memory provides enough capacity. All individual noises can be adjusted individually in the volume. The super-flexible sound engine without a rigid schedule allows the exemplary simulation of all conceivable rail tracks.

Functions

The LokSound 5 micro DCC Direct/Atlas Legacy decoders have up to 10 directly soldered LEDs. Two of them are intended for front and rear head lighting, two more are connected to the aux3 and aux4 outputs to switch e.g. number boards. A further 6 LEDs on the bottom are intended for ditch lights, but can also be used for other lighting purposes on request. All important lighting functions are available. The brightness of each output can be set separately.

Motor Control

The motor control of the LokSound 5 micro DCC Direct/Atlas Legacy decoders have a variable PWM clock frequency from 10kHz to 50kHz, which ensures super-quiet operation, especially for bell anchor motors – the hitherto typical “hum” is a thing of the past. The load control can be adapted to difficult cases with up to 10 CVs. The unique “Autotune” function allows the decoder to be automatically measured against the motor. The LokSound 5 micro DCC Direct/Atlas Legacy decoders deliver up to 0.9A motor power.

Protection

Of course, the outputs are protected against overload. We want you to enjoy your decoder for as long as possible.
