Volume Levels on the Amplifiers

Control Booth Amp:

Channels 1 & 2 should be at maximum output when in use when you are using the Soundcraft mixer. The volume is instead adjusted with the knob labeled "Control Room" on the Soundcraft.

Paging/Backstage Amp:

While you can make fine adjustments to the master volume output it should NOT be turned past the halfway point under any circumstances. If you need to make fine adjustments to the built in mixer on the amp you may do so. The bass & treble knob, and other switches on the amp should NOT BE ADJUSTED.


While the auditorium has 17 speakers with the capacity of adding two more passive speakers and additional powered speakers the speakers already installed in the auditorium provide excellent coverage and great sound.

Front of House Left & Right:

These are your primary go-to speakers. These are what get patched into the floor cart system and are adjusted with the yellow faders on the Sound craft in the booth. For most shows and events you will want everything to be routed in stereo. For theater shows where we use multiple speakers at once for surround sound these speakers are music and tracks left and right.

Center Left & Right:

The two center left and right speakers in the cluster above the pit serve as great backup speakers but don't have much fidelity as the two JBL front of house speakers. You can fix this by using the subwoofer which is controlled by adjusting Matrix 4 on the soundcraft mixer in the control booth. Most of the time these are not used. For theater shows where surround sound is used they serve as vocal and speech left and right. Center Left and Right can be adjusted with Group 3 and 4 on the soundcraft mixer.


On catwalk 2 towards back of house is a single Altec Lansing DTS-941 speaker. This is called the tier speaker and while it was designed to be used in tandem with the center left and right speakers it serves as a great fill in speaker for spoken word when used with the JBL speakers. You can use this tier speaker however you see fit as the front of house speakers already provide coverage to the tear seating area. For theater use this is sometimes used as a mono downmix for fill in. From a control perspective you can route front of house left and right into the tier speaker by pushing in the button labeled "L+R TO CENTER" on the soundcraft mixer. This button is located above the two yellow front of house master faders. If you wish to route individual audio sources or other sources to the tier mixer you can do so on the soundcraft by selecting your inputs individual on each fader by hitting the "C" button. Then de-press the button labeled "L+R TO CENTER" above the master front of house faders. Regardless of how it is setup the level of the tier speaker can be adjusted by moving the fader to the right of the two front of house faders labeled at Tier, this is called CENTER by the soundcraft mixer.


This speaker in between center left and right can be introduced when a little bit of bass is needed. While its not a true subwoofer speaker we have it configured to operate as one. You can adjust what is sent to the subwoofer and its output with Matrix 4 on the soundcraft mixer.

Stage Monitors:

We have two JBL MODEL NUMBER GOES HERE angled floor monitor speakers. These can connect to any speak-on connection in the auditorium that you need, as long as they are patched in in the control booth. These stage monitors have a variety of use cases, the most common being playing back music or tracks during a theater production. They operate on AUX 5 and AUX 6 on the soundcraft mixer as long as they are set to post fade (otherwise your gonna have a bad time).

Surround Left & Right:

Sometimes these are referred to or called the 'Portable' or 'Catwalk' speakers because of their location and label on their amplifier. Regardless of its name their function is the same. These two speakers are from the old gym sound system and where modified by Mr. Jaques to work with the auditorium. Despite their native use case they actually sound decent and get the job done for their surround/auxiliary use. These speakers can be adjusted with AUX 7 and AUX 8 on the soundcraft mixer as long as they are set to post fade (otherwise your gonna have a bad time). Most the time these speakers are off but they do have their use case. When the auditorium is confirmed to do 5.1 surround sound these serve as surround left and right. However they do have special use cases for theater shows depending on the show. Sometimes these speakers will be routed to the God Mic for theater rehearsals. This way the theater sound is completely separated and isolated.

Control Room Speakers:

Currently these will only output what ever is going to the two front of house speakers. This is a tad annoying in some applications such as theater when you need to hear everything but things can be modified by BHS IT if push comes to shove. These operate in stereo and are controlled by the knob labeled "C/ROOM" on the soundcraft mixer. The volume of these speakers will also adjust based on how the main front of house speakers are set so keep that in mind when setting the level of the control room.

Backstage Paging Speakers:

The backstage paging speakers are explained on another page of this website.


Although, students should never ever touch the speaker patch panel.

Speaker Patch Panel

At the bottom of rack 1 (control room left) is a custom made patch panel which controls the routing of the speakers in the auditorium from amps to speakers. In most cases this should be set the way it is shown on screen, however sometimes modifications must be made such as in the event of re-locating monitor speakers.

NOTICE: DO NOT USE THE PATCH PANEL TO RE-ROUTE AUDIO TO DIFFERENT SPEAKERS. This will just confuse everyone and should instead be done on patch panel B.

Portable Speakers:
The Left and Right Channel of the portable speakers amps (For the Catwalk/surround speakers feed into the two Channel A and B sockets allowing for you to connect two additional portable speakers.

A Note on the Front of House & Control Room Speaker Connections:

These are the four cables that come out from inside the rack. This is because of the modification that allowed for these speakers to be installed. They are labeled accordingly.
