Page 7: Product Description
It can be equipped with a specific system plug-in card for the top speaker and a sepa- rate system plug-in card for the subwoofer. The C2 Controller can be operated with all K&F loudspeakers for which a system plug- in card is obtainable:... - Page 8 With other (universal) controllers, the gain of the selected power amplifiers must be known. The limiter on the C2 Controller, on the other hand, uses a special control circuit to determine the actual output voltage of the power amplifiers. The limiter then reduces the input level only when the power amplifier actually pro- vides more power than the speakers can handle.

4. INPUT GAIN, level control The INPUT GAIN control is used to set the input level of the C2 Controller. The in- put level can be increased by 6 dB and reduced by 40 dB. In order to avoid over- loading the input section of the amplifier or the mixer output circuit, this control should normally be set at 0 dB. - Page 10 12. SIGNAL LEDs, display These LEDs are illuminated when power amplifiers are connected and their out- put signals are received by the C2 Controller. In exceptional cases, the Sense LEDs may still light up even when the po- wer amplifiers are turned off or disconnected. This situation can be at- tributed to the ‘‘microphone effect’’...

User’s Manual System Controller C2 13. LIMIT LEDs, display These LEDs are illuminated as soon as the output level of the relevant channel comes under the influence of the limiters on the controller. A gently engaging RMS limiter and a fast peak limiter limit the output of the power amplifiers virtu- ally inaudibly to the maximum permitted level. - Page 12 In such cases the connection must be made via capacitors. More details can be found in the manuals of the power amps in question. The input imped- ance of the C2 Controller is 220 kOhm. KLING & FREITAG GMBH ©2003 - 2006 Version 4.0, 23.03.2006...

System Controller C2 4. C2 Remote Control The Sub-D connector at the rear of the C2 Controller offers the facility of remote control of the functions listed below and / or the calling-up of status information. The Sub-D connector is not intended for connection to a computer. The contacts provide only analogue control and status signals. -

8. Recommendations for Configuration 8.1 Operating several Speakers per C2 Channel The maximum number of speakers which can be operated at one time using the C2 Controller is limited by the minimum output impedance of the power amplifiers. We recommend not more than 2 x 8 Ω loudspeakers per C2 Controller channel. -
Page 19: The Correct Balance Between Bass And Top Speakers
A bass speaker which is on the floor can be a few decibels louder than a flown bass system because of the floor reflections. The SUB GAIN control on the C2 Controller facilitates the correct setting of this balance according to configuration and application. - Page 20 User's Manual System Controller C2 2 x subwoofers (stereo) with 2 top speakers 2 subwoofers (stereo) with 4 top speakers 2 x CA 1201 4 x CA 1201 2 x CA 1215 4 x CA 1215 2 x CA 106...

Page 25: Avoiding Ground Loops
"ground loop" has not been built into the system. The C2 Controller as well as some power amplifiers facilitate a ground lift switch. Set the ground lift switch of the C" Controller to the 'Lift' position first. If the humming is still audible, then set the ground lift switches of the amplifiers to the 'Lift' position one after the other. -
