What's the difference between this and the balanced tour unit other than the number of inputs? Is it sonically the same?
What's the cost for a complete kit less enclosure, connectors etc?
The LDRxB (tour unit) has 3 XLR inputs, 1 RCA input, 2 XLR outputs and 1 RCA output.
The LDR1.V2B (it's LDR1, not LDR3...my mistake), since it's a single input, has no input switching hardware compared to the LDRx so it's arguably and cleaner connection. However, the audio input/output does have to go through a relay whereas on the LDRx it's all LDRs and no relays in the signal path. You could argue that the simplicity of the LDR1 may have a sonic edge over the LDRx but that's speculative.
Do not have a kit version of the LDR1.V2B at this time.
