4.1
INPUT CHANNELS
There are six input channels. Channels 1 & 2 are for microphones, Channels 3 through 6 are for line level sources,
e.g., CD players, tape decks, and other analog sources. Channel 6A is for playback from the PC.
4.1.1 MIC 1
Mic 1 is normally the console operator’s mic. Mic 1 is turned on and off using the red PGM button just above the
Channel 1 fader knob. When Mic 1 is ON, the LED above the button will light RED. The relative mix level is
determined by the FADER. If the announcer needs to cough, pressing the COUGH button will momentarily mute
the mic. If Mic 1’s Monitor Mute is set ON, the Monitor will mute when the mic is on. (See Section 2.1.1.)
4.1.2 MIC
2
Mic 2 is a secondary or “Guest” mic channel. It is turned on and off using the red PGM button just above the
Channel 2 fader knob. When Mic 2 is ON, the LED above the button will light RED. Mic 2 can also be mixed to the
Cue bus by pushing the blue CUE button, which will cause the LED to change from red to BLUE. If the channel is
in Cue mode, the Program assignment is overridden. The relative mix level is determined by the FADER. If the
announcer needs to cough, pressing the COUGH button will momentarily mute the mic. If Mic 2’s Monitor Mute is
set ON, the Monitor will mute when the mic is on. (See Section 2.1.1.) Note that the Monitor Mute function also
mutes the Cue speaker, to prevent feedback if Mic 2 is in Cue mode. The Cue function can be used as an
intercom, so that a guest (booth) announcer can talk to the console operator, off-air, via the Cue speaker.
4.2 LINE
INPUT CHANNELS
4.2.1 LINE CHANNELS 3 THROUGH 5
Line input Channels 3 through 5 are identical. Each Line channel has two inputs, A and B. The A input is the
“main” input; the B input is the “secondary” input. The active input is selected with the A/B Input Select button. If
the button is UP, the A input is active; if the button is DOWN, the B input is active. The LED below the A/B button
indicates which input is selected: GREEN = A, YELLOW = B.
A Line channel is mixed to the Program bus by pushing the red PGM button. The LED above the button will light
RED. The relative mix level of line sources is determined by the FADER. Line channels can be auditioned by using
the Cue bus. Pressing the blue CUE button will override the PGM bus assignment, change the LED from red to
BLUE, and send the (pre-fader) audio to the Cue speaker.
Note: Channel 5 also has a front panel 1/8” TRS jack, which is Input 5B. This input is connected in parallel with
the rear panel RCA jacks for Input 5B. The front panel jack can be used as a convenient way to “quick-connect”
any line-level source, e.g., an MP3 player or CD player. Use either the front panel jack or the rear panel jack, but
do not use both jacks at the same time.
4.2.2 LINE CHANNEL 6: THE SIXMIX USB CODEC
Line input Channel 6 is identical to input Channels 3 through 5, except that input 6A is internally connected to the
USB codec. If a computer is used via the USB connection, the computer’s audio will play through Channel 6A.
The Program mix is sent the computer via the USB connection for recording. “0-VU” on the SIX MIX VU meters
represents -15 dBfs. Higher recording levels can be achieved by simply increasing the levels as shown on the
meters. There is 30 dB of headroom above 0-VU; clipping should not occur. When recording on the PC, do not
assign Channel 6A to the Program bus, as excessive noise could result.
The computer should recognize the SIXMIX codec as “USB Audio Codec”. No additional software or drivers are
needed. Sample rates of 32.0, 44.1, or 48.0 kHz can be used. Any software that supports a USB sound device will
work with the SIXMIX. Set audio recording/editing software Settings to select USB Audio Codec as its default.
IMPORTANT! WINDOWS* VOLUME SETTING: Be sure to check the Windows “SPEAKER VOLUME” setting.
The Speaker Volume can be accessed via the Windows Control Panel under “Sound and audio devices” or “Adjust
the system volume”. Select “Volume” or “Set system volume”, then adjust the slider. The Speaker Volume should
be set to MAXIMUM.
