Turbosound ASPECT TA-880 사용자 설명서

The LMS-D6 audio inputs are RFI filtered and electronically balanced. The outputs are 
electronically balanced and fully floating. Overall, the unit is designed to operate at any 
signal levels ranging -10dBu up to +20dBu. The outputs will drive into loads of 600 Ohms or 
greater and both inputs and outputs are intended to be 'fuss free', regardless of an 
installation's complexity. 

The connector wiring is as follows: 

Input Output 

Pin 1 n/c 

Pin 1 n/c 

Pin 2 hot (+) 

Pin 2 hot (+) 

Pin 3 cold (-) 

Pin 3 cold (-) 

 

Balanced Wiring: whether a system is wired to a 'pin 3 hot' or a 'pin 2 hot' convention will 
not matter as long as the wiring of hot & cold phases to both the input and output XLR 
connectors is the same.  

At the LMS-D6 input, the convention is 'screen goes forward with the signal'. Input cable 
screening therefore needs to be connected at and derived from the signal source end, as pin 
1 on the input XLR is not connected to the LMS-D6 chassis nor signal ground.  

When a loudspeaker sound system is constructed which utilises different loudspeaker drivers 
for separate frequency bands, it is inevitable that the sound sources are non-coincident. The 
effect of this is that phase and time differences occur, producing a substantial cancellation of 
the signal around the crossover region. There is also a general lack of transient clarity or 
smearing of the sound, resulting from an inaccurate combining of the wavefront. The LMS-
D6 provides and maintains the optimum signal delay between the HF and HMF drivers and 
the LMF driver in the TFS-780H when the unit is switched to Flashlight mode, and in 
Floodlight mode the three drivers in the TFL-760H are physically aligned so inter-driver time 
delays are switched out. DSP settings for these and other Turbosound controllers are 
availalable from the Turbosound website Downloads area or the ftp site at
