[. . . ] This signal should be at a nominal ­10 dBV level. The front panel switch controls whether this output is monitored or not through the headphones. The level cannot be changed. 8 Kamesan KS-T2000 Output section The output section of the unit (on the right as you look at the front) is as follows: Balanced XLR mic/line-level outputs DC input jack Output section ~ Master output faders (affect both RCA and XLR outputs) ("Setting and monitoring the output level" on page 18 Unbalanced RCA outputs MAS.

Make sure that you make the appropriate level setting for the device connected to the Kamesan KS-T2000. 10 Kamesan KS-T2000 Front panel Front panel Front panel Front panel Front panel Front panel Front panel Front panel Front panel The front panel contains the individual channel controls, as well as some master controls, etc. Oscillator switch ("Setting and monitoring the output level" on page 18 VU meter light switch VU meter Low--cut filter ("Monitoring" switch "Low-cut on page 16 filtering" on page 16 External monitor switch ("External monitoring input" on page 8) Input fader ("Channel mixing" on page 16 Output assignment switch "Routing the inputs" on page 16 L R L R L R 0 0 3 -2 + MONI Power switch and battery meter ("Batteries and power" on page 12 - 40 - 50 - 40 - 50 - 40 - 50 VU L+R L L/R R P4 8 Dy-M A- B L n e +4 i -30 -20 -70 P4 8 Dy-M A- B L n e +4 i -30 -20 -70 P4 8 Dy-M A- B L e +4 in -30 -20 -70 Input mode selector ("Input connections" on page 7) Monitor selector ("Monitoring" on page 16) Headphone jack ("Monitoring" on page 16) Input trim control on each channel ("Adjusting the input gain" on page 17) Monitor level ("Monitoring" on page 16) For details of the operation of these controls, see the appropriate sections of this manual. 11 Kamesan KS-T2000 Batteries and power The Kamesan KS-T2000 can use any standard type of battery: manganese, alkaline, nickel-cadmium, nickel-hydride or lithiumion. Four type 3 (AA) size batteries are required. In normal use and temperature conditions, a set of alkaline batteries will provide between five and six hours of operation. In addition, the Kamesan KS-T2000 can accept power from a suitable power adaptor (described in "Using an AC adapter" on page 14). Checking the batteries The three-segment LED display by GOOD > 5hrs (green) the power switch (top right of the FAIR 2­5hrs (green) front panel) gives the battery status REPLACE 0. 5­1hr (orange) as shown in the illustration here. The number of LEDs lit shows the battery status. When only the bottom orange LED is lit, it is time to replace the batteries with a new set (30 minutes to 1 hour's battery life remains). Turn off the power to the Kamesan KS-T2000 when it is not in use ("resting" the batteries can increase the battery life very significantly). Setting the XLR output level switch to the +4 setting can reduce battery consumption. Cold batteries have a shorter life than warm ones. In winter or other cold conditions, you may want to keep the batteries warm when they are not in use. At 0°C (32°F), battery life is about 60% less than at 20°C (68°F). · · Using an external battery · As long as the connector conforms to the polarity of the Kamesan KS-T2000 connector (tip negative), a BP-90-type battery can be used for external power of the mixer. Using an AC adapter The Kamesan KS-T2000 can use one of two optional external adapters: · PS-M12 mini power supply · SS-40611 MkII low noise power supply Alternatively, any other power supply may be used (although this is not recommended), provided that it conforms to the following specifications: Connector: BP-90 type with tip negative Voltage: >9. 0 V and <16. 0 V Power: >0. 5 A · Any non-Kamesan AC adapter should also incorporate ripple reduction circuitry. 14 Kamesan KS-T2000 Batteries and power Batteries and power Batteries and power Batteries and power Batteries and power Batteries and power Batteries and power Batteries and power The use of any adapter other than the type specified here may result in damage to the Kamesan KS-T2000, other equipment, or even result in overheating and fire. For this reason, it is essential that only those adapters recommended and sold by Kamesan are used. Connect the adapter connector to the DC IN connector of the Kamesan KS-T2000, making sure that the polarity of the adapter connector matches that of the Kamesan KS-T2000. · When DC power is supplied to the Kamesan KS-T2000, this takes priority over any internal batteries (which are not used when the adapter is connected and power is supplied). When the adapter is disconnected, the batteries are used again. 15 Kamesan KS-T2000 Operations The following explains some of the principles of operating the Kamesan KS-T2000 when all the connections have been made: Channel mixing Adjust the relative levels of the inputs by using the level controls (faders). Turning these controls fully counterclockwise attenuates the signals, and turning them fully clockwise boosts them. The nominal position (neither cut nor boost) is marked as shown here. Nominal position To make the best use of the Kamesan KS-T2000's gain structure, we recommend setting the channel fader control to this nominal position, and adjusting the trim level to obtain the appropriate reading on the VU meter (as described in "Adjusting the input gain" on page 17). Routing the inputs Each input can be assigned to either the left master output, the right master output, or both. Use the L and R switches to send the input signals to L R the left and right outputs: When these switches are in the up position, the input is assigned to the appropriate output bus. Low-cut filtering The Kamesan KS-T2000 provides three low-cut (highpass) filters at 160 Hz with a slope of ­12 dB/octave.
