4.1 AC Power Connector
The amplifier module and any audio equipment connected to it (mixing consoles, processors, etc.)
must be properly connected to the AC power distribution, preserving AC line polarity. All grounding
points should be connected to a single node or common point, using the same cable gauge as the
neutral and line cables. Bad grounding connections within an audio system can produce noise,
hum and/or serious damage to the input/output stages in the system’s electronic equipment.
Important: Before applying AC to any Galaxy self-powered speaker, be sure that the voltage
potential difference between neutral and earth ground is less than 5 VAC.
4.2 Voltage Requirements
The GPS-8 operates safely and without audio discontinuity if the AC voltage
stays within either of two operating windows: 95-125 V at 50 or 60 Hz (Mains
Switch set on 110 V) or 195-250 V at 50 or 60 Hz (Mains Switch set on 220 V).
Be sure that both voltage set on the selector and AC Power have the same value.
Important: Connecting the speaker on a 220 V AC Power with the Mains Switch
set on 110 V will cause heavy damage to the device and serious risk for users.
4.3 Current Requirements
The GPS-8 presents a dynamic load to the AC mains, drawing additional current as operating
levels increase. Different cables and circuit breakers heat up at varying rates, so it is essential to
understand current ratings and how they correspond to circuit breaker and cable specifications.
Maximum continuous RMS current - measured over a period of at least ten seconds - is used to
calculate the temperature increase in cables, which drives the proper size and gauge cable and
rating for slow-reacting thermal breakers. Maximum burst RMS current - measured over a period
of approximately one second - is used to select the rating for fast reacting magnetic breakers.
For best performance, voltage drops should not exceed 10% at 110 V or 5% at 220 V.
