Audio
The SOLOIST-2S provides attenuation or gain capabilities for the Network, Soloist (MPEG 2 insertion
material) and Auxiliary sources. Settings: -16dB to +14 dB in 2 dB increments. This setting is momentary
and will revert to the current NetSet once a break starts.
For Balanced 600 Ohm systems
A) The Network setting is factory defaulted to –6dB. The – 6dB setting provides active termination
equal to 600-Ohms. This provides a balanced input during power on for the receiver. The internal
gain circuit provides a multiplier of 2. This limits the maximum input voltage to 1 V peak to peak. In
the event of a power loss to the SOLOIST-2S the active –6 dB termination is disabled and the
receiver will see the 600-Ohm load on the modulator. This eliminates the possibility of dual
termination.
B) The use of a 600-Ohm resistor on the audio input provides passive termination and will require that
the Network audio be set to +0 dB in the network setting. In this scenario, when power is lost, the
network audio will become doubly terminated (once at the SOLOIST-2S input and again at the
modulator).
C) If the 600-Ohm termination can be disabled on the modulator, the use of a passive 600-Ohm resistor
on the SOLOIST-2S input will provide proper termination in both power on and off states.
It is recommended to integrate the audio using A or C. If the audio still sounds distorted in either of these
scenarios, the input level to the SOLOIST-2S must be lowered to 1 V P-P.
