Overview:
Imagine a full-blown COMPOSER PRO—IKA compressor/limiter with switchable AUTO function, IRC expander/gate and IGC program/peak limiter, stereo link, selectable operating level and much more—plus 12AX7 tubes and ULTRATUBE circuitry, allowing you to sweeten and personalize your sound by adding the desired amount of harmonics, and you’ve got the T1952
Product Features:
- 5 dynamic processing functions: compressor/limiter, gate/expander, peak limiter
- IKA program-adaptive compression circuitry, IRC expander/gate circuitry, IGC peak-limiting circuitry
- Selectable “Interactive Knee” or “Hard Knee” compression modes
- Switchable Auto function for automatic attack and release time adjustment
- “Warmth” control allows precise dosage of desired tube effect
- True RMS stereo link selectable
- Switchable side chain input, monitor and high-pass filter
- Highly accurate metering for input/output level and gain reduction
- Relay-controlled hard bypass with auto-bypass function in case of power failure
- Servo-balanced inputs and outputs on gold-plated XLR and TRS connectors for highest signal integrity
- Shielded toroidal power transformer for ultra-low noise performance
- High-quality components and exceptionally rugged construction ensure long life
- Conceived and designed by BEHRINGER Germany
Expander /gate and compressor section
1.) The TUBECOMPOSER converts to stereo mode by engaging the CH1 MASTER switch,where the left channel assumes the control of both audio channels,i.e the control signal of channel 2 is replaced with that of channel 1 .
2.) Use the THRESHOLD control to determine the threshold point below which expansion occurs.
3.) The RATIO control is used to adjust the expansion ratio when the signal drops below the threshold value.
4.) When the signal level is below the set threshold value, the "-" LED lights up. The ""+" LED lights up when the signal level is above the set THRESHOLD value.
5.) To optimally adapt the expander/gate to the program material,the RELEASE switch allow for selecting a SLOW or FAST release time.
6.) The THRESHOLD control sets the threshold point for the Compressor section
7.) The RATIO control determines the ration between the input and output level for all signals exceeding the threshold point by more than 10dB.
8.) The ATTACK control determines the rate by which the compressor responds to the signal which exceeds the threshold.
9.) The RELEASE control determines the rate that the compressor returns to unity gain after falling below the threshold level
10.) By activating the AUTO switch,the ATTACK and RELEASE controls are disabled and the attack and releases rates automatically derived from the program material.
11.) The OUTPUT control allows for the increase or decrease o the output signal by a maximum of 20dB.
12.) When activated,the SC EXT switch severs the connection between the audio input and the side chain path,while at the same time allowing an external signal to be sourced at the SC RETURN jack on the rear panel.
13.) Using the SC MON switch will enable you to connect the side chain control signal to the audio output,whilst at the same time muting the audio input.
14.) The IN/OUT switch activates the relay and hence the corresponding channel.
15.) Press the INTERACTIVE switch to change from "Hard Knee " to IKA characteristics.
16.) The SC FILTER switch activates a high pass filter in the side chain path and thus limits the influence of low frequencies on the TUBE COMPOSER's control processes.
17.) The VU METER can display three levels: the actual gain reduction of the compressor ,and the input or the output level.
18.) With the GAIN RED/ LEVEL switch the above described VU meters can be switched bertween LEVEL or GAIN REDUCTION mode.
19.) If switch is set to LEVEL ,you can switch further between input and output level.
20.) The peak limiter limits the signal to a level adjusted with the THRESHOLD control.
21.) The LIM LED lights up as soon as the limiter function is activated.
22.) The WARMTH control determines the amount of harmonics the UTC circuit adds to the signal
23.) The WARMTH meter displays the amount of added harmonics.
24.) Use the POWER switch to turn the TUBE COMPOSER on or off.
Front Panel Features:
25.) SERIAL NUMBER - Please complete and return the warranty card within 14 days of the date of purchase
26.) FUSE HOLDER / VOLTAGE SELECTION - Before connecting , confirm that the voltage display matches your local mains voltage.
27.) AUDIO IN - These are the audio inputs of your TUBE COMPOSER ,available both as balanced 1/4" TRS and XLR connectors.
28.) AUDIO OUT - These are the audio outputs,which are also designed as 1/4" TRS and XLR sockets.
29.) With the OPERATING LEVEL switch you can adapt the TUBE COMPOSER to various operating levels,
30.) SC SEND - This is the unbalanced side chain output which allows for routing the audio signal to external processing devices.
31. SC RETURN- This is the unbalanced side chain input used to return any external or processed control signal.
