Quick Installation Guide for RA210/RA410
Required components for installation:
– 24VDC power supply with at least 2A
– speakers with 4 or 8 Ohms impedance
1. Mounting and connection
1.1 Mount the RA210/RA410 on a 35mm DIN-rail.
1.2 Connect cables to audio speakers (check polarity) and
power supply.
!Warning: Wrong polarity may damage the device!
Double check power cable polarity before connecting!
2. Operating modes
There are two dierent modes to operate the
RA210/RA410: mono and stereo.
Operating mode: Mono
In this mode both channels work separately. The power
amp switches on when
– the switching voltage at Control In is between 5 - 24V
– the voltage at the Volume input is ≥ 1V.
Operation mode: Stereo
In this mode both channels are connected via a wire
jumper between Control In On A and On B. In result, the
volume is controlled via the Volume Input A (0-10V).
3. Conguration*
The RA’s oers many conguration possibilities. In the
following, three common congurations are described.
Stereo conguration
In this conguration the RA210 is connected to another
trivum device (in this example: RP010). The volume of the
RA210 is operated via the Volume Output of the RP010.
Mono conguration with poti
In this conguration the volume is operated via a
potentiometer (poti).
Example: Mono Channel A
Example: Dual Mono Channel A/B
Mono conguration with Dim Actuator
In this conguration the volume is operated via a Dim
Actuator (not included). The Input Ref is connected to both
channels.
iNote:
Input Ref = 10VDCLCO
