Operating the C•que 8
SETTING UP THE C•que 8
Setting up your C•que 8 Headphone Amplifier is a simple procedure, which takes only a few minutes.
Remove all packing materials (save them in case of need for future service) and plug the provided AC adapter
cord in the rear AC inlet, but don’t plug the power cable into a wall outlet just yet.
• Connect the output from the device you want monitored to the Left/Right LINE INPUT jacks on the C•que
8 rear panel. The C•que 8 accepts both balanced and unbalanced signals. Generally, a balanced signal
is preferable because it provides better signal-to-noise ratio and reduced extraneous noise.
• Set the controls to the following positions:
MASTER VOLUME – Off
ST/2CH SWITCH – Out
MASTER BALANCE- Center, 12:00
CHANNEL 1 VOLUME – 0
CHANNEL 1 SHAPE SWITCH- Out
CHANNEL 2 - 4’s Controls - Set the Same as Channel 1
• Turn the master Volume knob and all four headphone Channel Output knobs to their minimum (fully
counterclockwise) setting.
• Plug the C•que 8 power adapter into a wall outlet and switch the unit on by pressing the power switch.
• Apply a signal, like the output of a mixer playing a CD, to the C•que 8’s rear-panel Left/Right LINE
INPUT jacks. Raise the master VOLUME until the main meter reaches -18 to -12 dB.
• Connect a set of headphones to Channel 1 and slowly turn the channel’s Volume knob clockwise until
you hear the desired level.
WARNING:
Because the C•que 8 is capable of generating extremely high volume levels, always start with the
channel Volume knob at minimum and then slowly turn it up.

Operating the C•que 8
• Repeat the previous step for all Channels that have headphones connected, making sure to start the
VOLUME knob completely counterclockwise and then slowly raising it until the desired level is achieved.
If you have connected different models of headphones to the various Channel Headphone jacks, you
may find that some require more gain than others to achieve the same volume. This kind of disparity will
occur if the various headphones have different impedances. The lower the impedance, the louder the
headphone will sound compared to another, higher impedance headphone at the same VOLUME setting.
Another factor affecting headphone loudness is called sensitivity. This is generally measured by determining the decibel (dB) level generated by 1 mW of power input. The higher the dB rating, the louder the
headphone. See the Reference chart on page 13 of this manual for more details.
• To achieve optimum signal-to-noise ratio, the master VOLUME should generally be set as high as possible, short of audible distortion. However, if this results in your getting blasted with signal even though the
channel volume is near minimum, you’ll need to decrease the Master Volume while raising one or more
channel volume levels. Conversely, if you find that you have to raise one or more headphone Channel
Volume knobs to maximum or near maximum to achieve the desired level, try increasing the master
Volume level while decreasing the channel volume(s).
SETTING UP THE C•que 8 - Continued
C•que 8 Master Section
Master Volume
The C•que 8’s master VOLUME control is used to adjust the input signal connected to the main Left and Right
inputs. In addition, the master VOLUME control adjusts the level of the signal inserted in the INJECT, which is
summed with the MAIN Left and Right input signal.
Balance Control
The C•que 8’s main channel has a BALANCE control,
which controls how much signal is sent to the left or right
headphone outputs. The control knob has a center detent
which indicates that the left and right sides are balanced.
In 2 Channel mode, the signal becomes mono and the
BALANCE knob adjusts the level balance between the
signals connected to the LEFT inputs and signals connected to the RIGHT inputs. (For more information on 2Channel mode, see the section “Mixing Signals in 2
Channel Mode” found on page 9 of this manual.)
Master Level meter
The C•que 8’s master section includes a 6 segment LED LEVEL meter which monitors the input level from the
MAIN Left and Right Inputs in Decibels (dBs) from –24 to OL (overload). If the LEVEL meter displays an OL signal, then turn down the signal using the master VOLUME control.
Master Inject
The C•que 8’s MASTER INJECT is a TRS input (Tip, Ring, Sleeve), that allows a second stereo signal to be
inserted and summed together with the MAIN Left and Right signals. You can use a stereo signal from your mixers bus outputs or auxiliary sends to balance the mix between two stereo signals like rhythm tracks and vocals.
2 Channel/Stereo switch
The 2 CH/STEREO switch is used to change between the C•que 8’s two global operating modes, 2-Channel and
Stereo. In Stereo mode the left and right Line inputs are mixed with the left and right Inject inputs, in stereo, with
the Balance knob controlling the left and right panning. In 2-Channel mode, the left and right LINE inputs are
mixed with the left and right INJECT inputs into a single mono signal with the BALANCE knob controlling the level
difference between the LEFT and RIGHT inputs.

Headphone Output
The C•que 8’s Headphone Output jack accepts a standard 1/4” TRS connector for easy interface with
most professional headphones. Once the master VOLUME has been set, the channels output level
is set by the VOLUME knob.
EQ Shape
Each of the four C•que 8 channels features an EQ
SHAPE switch allowing individual equalization contour for each channel. When the EQ SHAPE switch is
in, the LED will illuminate indicating the EQ SHAPE
circuit is engaged. The EQ SHAPE circuit provides a
pre-set equalization curve designed to sound good on
most program music. In this mode, the low frequencies have a 6dB boost at 100Hz and the high frequency are boosted 6dB at 12kHz. When the EQ SHAPE
switch is in the out position, frequency response of
the channel is flat.
VOLUME Control
The channel VOLUME control is used to adjust the channel headphone output. The volume control
will adjust the level of the front panel headphone outputs, as well as that channel’s rear panel headphone outputs.
CHANNEL LEVEL Meter
Each C•que 8 Channel has an 6 segment, LEDlevel meter which monitors the output of the channel in
Decibels (dBs) –24 toOL (overload). If the LEVEL meter displays an OL signal, then turn down the
channel VOLUME, and if necessary, also turn down the master VOLUME .

Operating the C•que 8
STEREO AND TWO-CHANNEL MODES
All of the C•que 8’s four channels can be set to operate in two different modes: Stereo and 2 Channel.
Stereo Mode
Stereo mode is a normal operating mode where all mix inputs from MAIN and INJECT, maintain their stereo
image throughout the signal path to each headphone output. The BALANCE control is used to adjust the stereo
image between the Left and Right side. To design a monitor mix in the Stereo mode, follow these steps:
• Press the ST/2CH switch to the OUT position. You’ll notice the switch LED is not illuminated indicating
that the main input is in STEREO mode.
• Make a Stereo connection from your mixer’s auxiliary or bus outputs to the main Left and Right Line
inputs on the C•que 8’s rear panel.
• In the Stereo mode, the BALANCE control adjusts the loudness between the left and right headphone
outputs.
Mixing Signals in 2-Channel Mode
In 2-Channel mode, the MAIN left and right inputs and the INJECT left and right inputs are summed to a common
mono signal that is present on all of the C que 8’s headphone outputs. The BALANCE control is now used to
adjust the volume difference between the left and the right inputs. In a recording situation, you can use the 2Channel mode to make a “More Me” cue mix, letting you adjust the volume of the mix directly on the C que 8. To
design a monitor mix in the 2-Channel mode, follow these steps:
• Press the ST/2CH switch to the IN position. You’ll notice the
switch LED is now illuminated indicating that the C•que 8 is
in 2-Channel mode.
• Create a mono monitor mix on one of your mixer’s auxiliary
sends and make a connection from that aux send output to
the MAIN Left input on the C•que 8’s rear panel.
• Use your mixer’s direct output, or another aux send, to route
the signal of the lead vocal channel and make a connection
from that output to the C•que 8’s MAIN Right input.
• Now, you can use the BALANCE control to adjust the level
difference between the monitor mix and the vocal channel.
By using a combination of the MAIN VOLUME and BALANCE controls you can dial up the perfect mix directly on the
C que 8.

C•que 8 Connections
Because the C•que 8 Stereo Link output jacks are electronically balanced, we recommend the use of 3-conductor
cable and 1/4" TRS (Tip/Ring/Sleeve) connectors. Even when several C•que 8’s are linked together this way,
there is no loss of power or audio fidelity—every Channel on every C•que 8 will sound just as loud and clear as if
it were the only unit connected. The status of the front-panel Stereo/2 CH buttons affects only that unit and has
no effect on any subsequent linked units.
Any number of C•que 8’s can be linked together (daisy-chained), allowing you to monitor an input signal over
more than twelve sets of headphones, or to give individual musicians more control over their own headphone
mix. To do this, simply follow these basic steps:
• Make a connection between one C•que 8’s Left/Right Link outputs and the next one’s Left/Right Main
inputs.

C•que 8 Connections
Virtually all headphones that terminate in a stereo 1/4" plug can be used with the C•que 8 Headphone Amplifier.
This chart provides a partial listing of some of the more popular models, along with their impedance and sensitivity ratings. As described on page 7 of this manual, headphones with lower impedances (or higher sensitivity) will
sound louder as compared to other, higher impedance (or lower sensitivity) headphones at the same channel
Volume setting. Samson Technologies has no connection with any of these manufacturers, nor do we endorse
any particular models for use with the C•que 8. This is simply a reference listing for your convenience. For more
information about any of these headphones, contact the manufacturer directly.

CUE MIX SET-UP FOR MULTITRACK VOCAL RECORDING
The following example shows a headphone mix for a vocal overdub session. The backing music and vocals are sent via the mixers
auxiliary sends to the C que 8’s MAIN input. The lead vocal channel is connected from the console’s direct output to the C que 8’s mas-
ter INJECT input. The C cue 8 is set to 2-channel mode, so that the BALANCE controls the level difference between the backing track
and lead vocal. This allows the lead vocalist to control the balance between his track and the backing tracks for a “more me” mix.

The following example shows a sophisticated cue mix for tracking a rhythm section during a recording session using five C•que 8’s. The complete mix for all the
musicians is sent via the console’s auxiliary send to the C•que 8’s RIGHT LINE input and daisy-chained from unit to unit. Then signal from each instrument is con-
nected from the console’s direct outputs to each of C•que 8’s master INJECT inputs using a mono 1/4-inch (TIP/SLEEVE) cable. (By using a mono 1/4-inch cable only
the Left Inject input is connected). The C•cue 8’s are set to 2-channel mode, so that the BALANCE controls the level difference between the backing tracks and indi-
vidual instruments. This allows the lead vocalist or musician to dial up his or her own track for a “more me” mix.
