DIRECT OUT Jack

These are impedance balanced (page 19) phone-jack type outputs. They output the signal that has passed through the compressor.
Turn off the Yamaha PW8 power supply before you connect or disconnect any cables to or from the console. If necessary, the signal that is output from the DIRECT OUT jack can be changed to the signal immediately before the channel fader (pre-fader) or the signal after the channel fader (post-fader) by changing an internal jumper. A fee will be charged for this modication. For details, contact to your Yamaha dealer listed at the end of this manual.

INPUT Jack (monaural)

These monaural input jacks are used to connect microphones or musical instruments. Each input channel features two types of jacks (INPUT A and INPUT B).

INPUT Jacks (stereo)

These are stereo input jacks that connect line-level instruments, such as a synthesizer. Each input channel features two types of jacks (INPUT A and INPUT B).

INPUT A Jack

These are balanced XLR-3-31 type input jacks (1: Ground; 2: Hot; 3: Cold).

INPUT A Jacks

These are unbalanced phone-jack stereo line inputs.

INPUT B Jack

These are TRS phone-jack type balanced inputs. (T: Hot; R; Cold; S: Ground) You can connect either balanced or unbalanced phone plugs to these jacks.

INPUT B Jacks

These are unbalanced stereo RCA pin-jack line inputs.
Only one type of jack can be used at a time on a single channel.

INSERT Jack

These jacks are located between the compressor and equalizer of the corresponding monaural input channel. The INSERT jacks are ideal for connecting devices such as graphic equalizers or noise lters into the corresponding channels. The INSERT jacks are TRS (tip, ring, sleeve) phone jacks that carry both the send and return signal (tip = send/out; ring = return/in; sleeve = ground).

Even if the ON switch is off, you can turn on the PFL switch (K) and monitor the signal before the channel fader via the MONITOR OUT jacks and the PHONES jack.

Input Meter

Three LEDs indicate the input channel signal level after the equalizer. The -20 LED will light if the input signal level reaches -20 dB, and the 0 LED will light at nominal level. The PEAK LED will light red when the input signal reaches 3 dB before clipping.

Bus Assign Switches

These switches determine the bus(es) to which each channels signal is sent. Turning a switch on will output the signal to the corresponding bus.

Stereo channel

Band HIGH HI-MID LO-MID LOW Type Shelving Peaking Peaking Shelving Frequency 10 kHz 3 kHz 800 Hz 100 Hz 15 dB Maximum Cut/Boost
1-2, 3-4, 5-6, 7-8 switches: Assign the channels signal to the GROUP 1/27/8 buses. ST switch: Assigns the channels signal to the Stereo L and R buses. MONO switch: Assigns the channels signal to the MONO bus.
If you want the signal to be output to the corresponding bus(es), turn on the channel ON switch (G).

EQ ON Switch

Switches the equalizer on or off.

AUX Controls (18)

These adjust the level of the signals sent from the input channel to AUX buses 18. These knobs should generally be set close to the (nominal) position. The signal adjusted by these controls is determined by the PRE switch (D).

MUTE Switches (14)

These assign the channels mute on/off to switches 14. If you turn on the MUTE master switches (14) (page 15) located in the MUTE MASTER section, the input channels whose corresponding MUTE switch is on will be muted.

PRE Switches

For each two buses, these switches select whether the signal sent to the AUX buses will be taken after the equalizer and before the channel fader (pre-fader), or after the channel fader (post-fader). If this switch is ON, the pre-fader signal is sent to the AUX bus, and will not be affected by the channel fader.
When a channel is muted, the ON indicator (G) will go dark. Even if a channel is muted, you can turn on the PFL switch (K) and monitor the signal before the channel fader via the MONITOR OUT jacks and the PHONES jack.
If necessary, the pre-fader signal sent to the AUX buses can be changed to the signal before the equalizer by changing an internal jumper. A fee will be charged for this modication. In this case, the signal will be sent to the AUX buses even if the input channels ON switch is turned off. For details, contact to your Yamaha dealer listed at the end of this manual.

PFL Switch/Indicator

When you turn on the PFL switch, the PFL indicator of the MONITOR section (page 18) will light.

Channel Fader

Adjusts the output level of the input channel signal. Use these faders to adjust the balance between the various channels.
To minimize noise, the faders of unused channels should be set to the lowest position. The channel faders will affect the ST, MONO, GROUP 1 8, and AUX 18 (when the PRE switch is off) buses.
When the PFL switch is on, the indicator will light and the channel pre-fader signal is output to the PHONES and MONITOR OUT jacks for monitoring.

2TR IN/USB Section

Rear Panel Front Panel

AUX RETURN Jacks

These are unbalanced phone-jack type line inputs. Signals input from these jacks can be sent to the GROUP 1/ 27/8, ST L/R, MONO, and AUX 14 buses. To the MONO and AUX 14 buses, a mix of the L/MONO and R signal is sent. These jacks are typically used to receive the signal returned from an external effect device (reverb, delay, etc.).
These jacks can also be used as auxiliary stereo inputs. If you connect to the L/MONO jack only, the mixer will recognize the signal as monaural and will send the identical signal to both the L/MONO and R jacks.

If both the ST switch and the MONO switch are on, the mixed signals of the ST L/R bus and MONO bus will be output.

MATRIX OUT Section

These switches determine the bus(es) to which the signal received from the 2TR IN jacks and the USB connector is sent. ST switch: Sends the signal to the ST L/R bus. MONO switch: Sends the mixed L and R signal to the MONO bus.

2TR IN/USB Control

Adjusts the level of the signal received from the 2TR IN jacks and the USB connector.
When the PFL switch is on, the indicator will light and the signal before the 2TR IN/USB control is output to the MONITOR OUT and PHONES jacks for monitoring.

REC OUT/USB Section

MATRIX OUT Jack
This is an impedance balanced (page 19) TRS phonejack type output. This jack outputs the signal adjusted by the controls in the MATRIX OUT section.

REC OUT Jacks

These RCA pin jacks can be connected to an external recorder such as an MD recorder in order to record the signal of the ST L/R bus or MONO bus.

GROUP Controls (18)

These adjust the level of the signals sent from GROUP OUT 18 to the MATRIX OUT jacks.
The STEREO OUT master fader and MONO fader has no affect on the signal via these jacks.

ST Controls (L, R)

These adjust the level of the signals sent from ST OUT L/ R to the MATRIX OUT jacks.

MONO Control

This control adjusts the level of the signal sent from MONO OUT to the MATRIX OUT jacks.

TALKBACK Section

MATRIX master Control
This control adjusts the overall level of the signal output to the MATRIX OUT jacks. The position of the knob is nominal level (0 dB).

AFL Switch/Indicator

When the AFL switch is on, the indicator will light and the signal after the MATRIX master control is output to the PHONES and MONITOR OUT jacks for monitoring.
If you want to monitor the signal after the MATRIX master control, turn off all PFL switches.

DC POWER INPUT Section

TALKBACK MIC IN Jack
This is an XLR-3-31 type unbalanced input jack for connecting a talkback microphone.

DC POWER INPUT Connector

Connects the Yamaha Power Supply PW8 to the console using the included power supply cable.
These determine the output destination of the signal from the TALKBACK MIC jack. AUX 1-2, 3-4, 5-6, 7-8 switches: Send the signal to the AUX 1/27/8 buses. GROUP 1-8 switch: Sends the signal to the GROUP 18 buses. STEREO/MONO switch: Sends the signal to the ST L/R and MONO buses. MATRIX 1-2, 3-4 switches: Send the signal to the MATRIX 1/2 or 3/4 buses.

When the AFL switch is on, the indicator will light and the signal after the MONO fader is output to the MONITOR OUT and PHONES jacks for monitoring.
If you want to monitor the signal after the MONO fader, turn off all PFL switches.

MONO Fader

Controls the level of the signal output to the MONO jack.

LAMP Connector

This is an XLR-4-31 type connector that supplies power to a separately sold gooseneck lamp (e.g., Yamaha LA5000). The IM8-40 mixer has three of these connectors, and the IM8-32/24 mixers have two.

MONO INSERT Jack

This is an input/output jack located before the MONO fader. You can connect a graphic equalizer or other signal processor. This is a TRS (tip, ring, sleeve) phone jack that carries both the send and return signal (tip = send/out; ring = return/in; sleeve = ground).

MONO OUT Jack

This is an XLR-3-32 type balanced output jack that outputs the MONO OUT signal.

Impedance balanced:

Since the hot and cold terminals of impedance balanced output jacks have the same output impedance, these output jacks are less affected by induced noise.
When this switch is on, the MONO OUT will be enabled and the indicator will light.

Troubleshooting

Power doesnt come on.
Is the dedicated PW8 power supply properly plugged into an appropriate AC power outlet? Is the dedicated PW8 power supply properly connected using the included power supply cable? The PW8 itself will not power-on unless it is correctly connected via the included power cable. If the above checks do not identify the problem, call Yamaha for service.
The sound of the bass drum will not move forward in the mix.
Could you be mixing a phase-reversed signal? Try turning on the switch to reverse the phase. If you are capturing the sound using multiple mics, phase reversal may be causing cancellation.
How can I send the pre-EQ signal to an AUX bus for monitoring?
You can send the pre-EQ signal to an AUX bus by changing an internal jumper setting. Turn the AUX PRE switch on (pre-fader). In this case, the signal will be sent to the AUX bus even if the input channels ON switch is off.
How can I monitor the signal of a GROUP bus before I send it to the ST L/R bus?

With the GROUP section ON switch turned off, turning the GROUP section AFL switch on will let you monitor the AFL signal of the GROUP bus without sending it to the ST L/R (and MONO) bus.
How can I send a compressed signal to the ST L/R bus while sending the uncompressed signal to DIRECT OUT jacks for recording?
If you connect a compressor (external device) to the INSERT jacks and apply compression to the signal being sent to the ST L/R bus, the signal before the compressor will be sent to the DIRECT OUT jacks. In this case, turn off the IM8s COMP control.
How can I send the TALKBACK signal only to the intercom?
In the TALKBACK section, turn on only MATRIX 1-2 (or MATRIX 3-4) to send the output of MATRIX 1-2 (or MATRIX 3-4) to the intercom.
How can I play background music from a portable audio player?
A standard mini-phone type 2TR IN jack is provided on the front panel, allowing you to connect your portable audio player via a mini-plug cable.
How can I assign the MC to the MONO bus and also record it?
Assign the MCs input channel to the MONO bus, and use the REC OUT section bus assign switch to select the MONO bus.
