33、e of 3.1, the GROUP/AUX OUT (1) OUT output level shall be within the range (Table 3.5) using the level with SW OFF as a reference. Table 3.5 HPF FREQ MIN MAX 20Hz -32 400Hz -32 Table 3.5 Measure the output at GA2, with an input at ST IN (R). When an output is generated at GA1 from TB IN while in the

34、 state of 3.2, set the frequency to 80Hz, and check that the level is -3 2dB when the 80 switch is ON using the level when the switch is OFF as a reference. 3.6 Separation While set in the status in 3.1, set the ST ASSIGN SW to ON in each IN and ST IN module, rotate the PAN control all the way count

35、erclockwise, and with the output level of ST OUT L set to +20dBu, the ST R leakage level shall be -60 dBu or less. With the PAN control rotated all the way clockwise, and the ST R output level set to +20dBu, the ST R leakage level shall be -60 dBu or less. During ST IN, apply the same signal to both

36、 L and R, and inspect both L BAL/R BAL. 3.7 VCA limiting (use a 30kLPF) Set the input level of each module for INPUT channels 1 - 24, 32, 40, 40 to -46dBu, while set in the state in 3.1. Then set the G/A Assign switch to ON, and with the INPUT FADER position set to MIN, the output level of G/A 1 OUT

37、 shall be within -58dBu. Also, set the input level of each module for ST IN 1 - 4 (L) to -46dBu. Set G/A Assign switch to ON, and with each INPUT FADER position set to MIN, the output level of G/A 1 OUT shall be within -61dBu. Measured at G/A OUT 2 with a signal applied from ST IN (R).

39、ED (CH INPUT METER) lighting level While in the state of 3.1, with the GAIN Trim of each IN and ST IN module set to MIN and an input signal applied, the input level to light up each CH INPUT METER LED shall be within the range of Table 3.8. With the EQ at ON and a +12 LED lighting level, the PEAK LE

40、D should also light when the EQ HI GAIN is set to MAX. With the INSERT switch set to ON, only the PEAK LED will satisfy the conditions of Table 3.8, even when there is no INSERT IN input. When the PAD switch is set to ON with all LEDs lit up, the LED will turn off in order starting from the top. Als

41、o, when all LED are lit up, turning the PANEL LED DIMMER VR to MIN will darken the LED. 3.9 Distortion In the sections in Table 3.2 with the mark, set the GAIN control of MONO IN, ST IN to MIN, and with each VR and FADER of MONO IN and ST IN, MASTER set to nominal position, the distortion obtained a

42、t an output of +14dBu at each output terminal shall be 0.025% or less at 20Hz and 1KHz, and shall be 0.04% or less at 20KHz. The channel distortion shall be measured at the OUT of any one of the channels. Even if all the MATRIX MIX VR at ST MATRIX OUT, MATRIX OUT have deviated from their specificati

43、ons at MAX, if even just one of the MATRIX MIX VR of the system being measured satisfies the specifications at MAX, then that is sufficient. TB OUT shall be inspected in the same way as with the input terminal for TB IN. However, the distortion shall be within 0.1%. The distortion when a 0dBu output

44、 is obtained at the PHONES (L,R), (1,2) terminals shall be within 0.7%. However, the PHONES measurement shall be made at each terminal. 3.10Maximum output In the state in 3.9, the output obtained at each output terminal on the system marked with a shall be +24dBu with distortion of 1% or less. An ou

45、tput of +3dBu and 1% distortion shall be obtained at the PHONES (L, R), (1,2) terminals. However, the PHONES measurement shall be made at each terminal. The systems through PAN (BAL) VR shall be measured with the overshoot to L (or R). 3.11OUTPUT LED METER, PEAK LED In the state in 3.1, with an outp

46、ut level of 4dBu at ST AUX OUT 1 - 12 (L, R), G/A OUT 1 - 8, ST OUT (L,R), MONO(C) OUT, the semifixed VR at the marks on the MT sheet of Figure 3,11 shall be adjusted only when the point where the 0 LED of the OUTPUT LED METER starts to light up, exceeds the range of +40.5dBu. The lighting level of

47、each LED (after adjustment) shall be within the range of Table 3-11. Further, when all LEDs are lit up, switching a Master ON switch to OFF will make all LEDs turn off in order starting from the top. MT sheet After switching to MATRIX with the METER SELECT switch set to ON, the 0 LED shall start to light up at an output level for MATRIX 1 - 8 in a range of +4 1.5dBu. Further, when the PEAK LED of each master LED starts to light, the output for each corresponding MASTER INSERT OUT shall be +21 2dBu. PM5000 2
