Gilderfluke&Co Amp-50 Class D Stereo Audio Amplifier - Manual (Page 2)

Line Level Inputs:
Two RCA line level inputs are available on the Amp-
50s. A line level audio signal from a Sd-10 audio re-
peater, pre-amplified microphone, CD player, Video
projector, or any other line-level audio source can be
plugged into these two RCA jacks. Two trimpots can
be used to adjust the levels of the mixer inputs.
Power Supply:
The Amp-50 will run on any voltage from 12 through
24 vdc. Size your power supply so it will provide
enough current for the volume you are planning to
run at. The amplifier will put out more power at 24
volts than it can at a lower voltage. If using all 50
Watts of the amplifier power, you will need to use a
24 volt supply rated at least 60 Watts. If you hear
clipping, the speakers or power supply may be un-
dersized for your application.
The power supply can be attached through the 2.1
mm power jack, or the screw terminals. Power Sup-
ply voltages higher than 24 vdc can damage the
amplifier on the Amp-50.
Volume Controls:
A pair of small trimpots on the Amp-50 are used to
set the audio output level. You can adjust these pots
using a small ‘trimmer’ screwdriver.
These trimpots are smaller than you. Do not use a
big screwdriver on them. Do not apply too much
force. They will break!
Amp-50 Installation:
The Amp-50 can be mounted using two screws;
DIN rail adapters; 2–3/4” Augat ‘Snap-Track’ (which
itself can be DIN rail mounted using DIN rail adapt-
ers); or just Velcro’d down. In many applications, the
Amp-50 can be attached on (or in) the speakers it is
feeding. The Amp-50 must not be mounted where it
might get wet, or suffer from extremes of tempera-
ture.
Unless the amplifier is being run at extreme output
levels, the Amp-50 will generate very little heat. At-
taching it to something metal will allow it to dissipate
what little heat it does generate.
