Model NV-LSI24
Mute Interface Module
The connection from the LSI24 is made through the
NV-IG8LSA RJ45 port on the back of the Control Pad
terminated with standard 568A. The connection at
the LSI24 requires the use of the Brown lead for
positive and Brown Stripe for negative.

NV-LSI24 Local Source Interrupt (Fig. 52)
The Local Source Interrupt enables an amplified local audio source to override the Grand Concerto System and play through the
local zone in-wall speakers. The most common scenario for this is a television that would benefit from higher-quality speakers.
The back of the Grand Concerto Control Pad has two CAT5 inputs. One is labeled NuVoNet and is the CAT5 that runs to the EZ Port at
the head end. The other is labeled NV-I8GLSA. This is intended to react to the LSI24 accessory. It requires an RJ45 connection at
the Control Pad end and the Brown and Brown Stripe pair as a voltage trigger.
Note that the Local Source Interrupt is a passive non-amplified device. The signal sent to it must be amplified.

Fig. 52
The positive and negative connection on the
LSI24 act as a relay relay switch between the
local source input and the audio coming from
the Grand Concerto System. When zone is
turned off, is routed to the speakers. When
the zone is on, the Grand Concerto audio goes
to the speakers.
Two or four conductor speaker wire from the
LSI24 to the zone speakers.
Speaker input from Grand Concerto
Amplified signal from the local zone source
The selected zone speaker output of the Grand Concerto
amplifier is wired directly to the LSI24
