Controls and Functions D REVERB TYPE/TIME control Determines the reverb type and length. Turning the control to the right lengthens the time of the selected reverb type. HALL: Simulated reverb of a large space, such as a concert hall. PLATE: Simulated metal plate reverb, producing a more hard-edged and bright sound. ROOM: Simulated acoustic ambience of a small room. ECHO: Echo effect suitable for vocals. E REVERB controls (channels 1-4) Determines the amount of reverb for each channel when the REVERB switch C is on. F ST/MONO switches STAGEPAS 600BT (channels 5/6, 7/8, 9/10) STAGEPAS 400BT (channels 5/6, 7/8) Setting the switch to ST (STEREO) (/) will assign the signals from the L and R channels to each left and right speaker and output each signal. Setting the switch to MONO (0) will mix the output of different L and R sources to output the same signal to both the left and right speakers. For keyboards with mono output, guitars, or other non-stereo sound sources, when the switch is set to MONO (0), the stereo input jacks can be conveniently used as multiple mono jacks. G LEVEL meter The LEVEL meter shows the level of output signal from the SPEAKERS L/R jacks. Notice If the unit is operated at a sufficiently high volume to make the LIMITER LED flashes continuously, the internal power amplifier section is being excessively overloaded and may malfunction. Reduce the output level with the MASTER LEVEL control so that the indicator flashes only briefly on the highest transient peaks. H POWER LED This LED lights when the power is turned on by pressing the power switch. I FEEDBACK SUPPRESSOR switch/LED When this switch is on, the LED lights up, indicating that feedback is automatically suppressed. (This configuration utilizes a seven-band notch filter. When this switch or the power switch is off, the notch filter will be reset.) J LEVEL controls Use these controls to adjust the volume for each channel. To reduce noise, set any LEVEL controls on unused channels to the minimum. K MASTER EQ (equalizer) control Use this control to adjust the overall sound frequency balance. The center position "MUSIC" is a basic setting. If you turn the control counterclockwise, it will create an optimum setting for speech, cutting unneeded low range frequencies. If you turn the control clockwise, it will create an optimum setting for playback of sound sources, since the low range is boosted. If you turn the control further clockwise, the LED will light up, indicating that the bass boost function turns on, giving you an even more powerful bass tone. L MASTER LEVEL control Determines the volume of the signal output from the SPEAKERS L/R jacks. This allows you to adjust the overall volume without changing the relative volume balance among the various channels. M Vents These are the vents for the cooling fan inside the mixer. Do not block the vents when in use. N AC IN jack Connect the included power cord here. O 1 (power) switch For turning the power of the mixer on (0) and off (/). NOTE Rapidly turning the unit on and off in succession may cause it to malfunction. After turning the unit off, wait for about 5 seconds before turning it on again. 10 STAGEPAS 600BT/STAGEPAS 400BT Owner's Manual
