•Disconnect Speaker(s) from the 50.2
•CD Software used to set levels is a test tone of 1kHz at “0dB” or “All Bits High”
•Source Unit set to 3/4 volume (or maximum unclipped output)
•Remove BLT Cover to access test pads and gain pots
•AC Voltmeter set to AC Volts
•AC Voltmeter
•AC Voltmeter “+” connected to test pad inside the BLT
•Adjust BLT Gain from 2.9 VRMS min. to 9.3 VRMS max per test pad (see chart below) Be sure the time index reads greater than 30 seconds on source unit.
| Gain Overlap | BLT Output (AC Volts) | Performance Characteristics |
|
|
| |||
|
|
|
|
|
| +0dB* | 2.9 VRMS | Best S/N Ratio, Reduced SPL |
|
|
|
| (Used for Optimum Sound Quality) |
|
|
|
|
|
|
| +5dB | 5.2 VRMS | Good S/N Ratio & SPL |
|
|
|
| (Use for Audiophile Listener) |
|
|
|
|
|
|
| +10dB | 9.3 VRMS | Best Compromise between S/N Ratio & SPL |
|
|
|
| (Used for Average Listener) |
|
|
|
|
|
|

|
*Absence of gain overlap will reduce SPL and may not permit amplifier to reach full output power due to various CD software.
