Basically, the larger the sound chamber, the better the sound (bass). However, it
may be that the sound is distorted due to excessive sound chamber: Often some
sounds were amplified directly in the decoder, which overwhelmed the sugar
cube speakers. Reduce in such cases, the overall volume of the decoder (sound
decoders: reduce CV 63) or reduce the height of the sound chamber.

6.9.1.2. use multiple speakers

Want to use multiple speakers, you need to consider the polarity of the speaker.
If any of the speaker is "backwards" wired compared to other speakers, the
membranes are moving in opposite phase. This results in a cancellation of the
sound waves and thus extremely poor, soft sound. As many speakers have no
pole ungskennzeichnung, you must try the phasing in doubt before the definitive
installation!

6.9.2. LokSound XL 5

The LokSound 5 XL has two speaker outputs that operate with about 10V. At
each can independently of each other speakers of different size and impedance
reasonable to be closed. In order for this double amplifier works best for you,
consider the following:
• If you use 4 ohm speaker, you should connect it only one of the two speaker
outputs. Up to 12W output power are possible
• Would you like to use both speaker outputs, each speaker should have an
impedance of 8 ohms or higher. Up to 2x 6 Watt are possible.
•
When overloaded, the power amplifier automatically switches off or the sound is
distorted
• Both speaker outputs provide identical sound data.

6.9.2.1. Volume control ext.

For each speaker output LokSound XL 5 a volume control can optionally be
connected. Use potentiometers with 100kOhm impedance and> 0.1W power (eg
Piher PT 10 LV). Look for the shortest possible wiring be- tween decoder and
adjustment control to avoid noise.
