Output Attenuation; Gain/Sensitivity - Outline TFive User Manual

Professional amplifiers
To better handle the huge amount of parameters, the single value numeric input mode is extended with a fine/coarse
feature. When you edit one of the parameters, you will start in the "fine" mode. The steps applied by the - and + keys
are the minimum allowable for that parameter. By clicking the "fast" key shown in figure 2.3.3, you will switch in the
"coarse" mode, and the key will be renamed as "slow" as shown in figure 2.3.4 . In the coarse mode, the steps are
equivalent to 10 steps of the fine mode, so that editing will be 10 times faster. Remember that by keeping the - or +
key pressed, the steps are automatically repeated.

2.3.1 Output attenuation

The figure 2.3.5 shows the Output attenuation screen. You can choose to set CH1, CH2 or both by pushing the "C1+2"
button. The "+" and "-" buttons change the value of the output attenuation in the range from 0 to -30dB.
Note: for the best sonic performance it is preferred to set the 0db output attenuation (no attenuation), and
select the proper gain/sensitivity by the following menu.

2.3.2 Gain/Sensitivity

The figure 2.3.6 shows the Gain/Sensitivity screen. You can choose to set CH1, CH2 or both by pushing "C1+2"
button. The "+" and "-" buttons change the value of the gain. The values of gains permitted are 26, 29, 32 and 35 dB;
the corresponding values of sensitivity and maximum input voltage are written in the table below.
