Combiner


This versatile box is built with our premium TRSP-2 transformer for 
optimum durability. 
• Use fewer input channels by combining two mic lines into one. 
• Combine two mics out of phase to remove background noise and feedback. 
• Correct and combine phase when using a pair of mics above 
  and below a drum.

Input Impedance: 150 Ohms x 2 
Output Impedance: 150 Ohms 
Operating Level: -50dBu to -10dBu 
Frequency Response: 20Hz-20kHz ±1dB

IMP LINE LEVEL COMBINER (IMCOML)

Use the line level combiner when you want to create a mono mix from a 
stereo source but need to keep the original stereo signals 
isolated. It's great for feeding a DAT player or CD into a mono system 
or single channel on a board. The LLC not only combines two line-level 
signals into one line level output, it also compensates for the 6dB of 
gain that occurs when two in-phase signals are combined. A handy 
ground-lift switch breaks the shield connection between the inputs. 
 


Frequency response: ±0.3dB 20Hz-20kHz 
Total harmonic distortion + noise: (0.025% at 1kHz 
Isolation between inputs") 42dB 
Insertion loss: -0.6dB, 50 Ohms source impedance -3.8dB, 200 Ohms source impedance 
Output level: -3.8dB with both channels at 0dB sine wave input, in phase 
Maximum input level: +28dBm 
Input impedance: 600 Ohms 
Output impedance: 100 Ohms

SELECTOR ®
 
This box gives you the ultimate control over your instruments and your 
gear. You can alternate between channels A and B, or select both. Thanks 
to our patented, state-of-the-art optical switching, there's no added 
noise, pops, or crackles. Indestructible foot switches let you make your 
choice with little effort.  Run it on one standard 9V alkaline battery or 
an optional external 9V power supply (T401-ND).
Impedance in and out: 1M Ohms 
Operating Level: -40dBu to 0dBu 
Frequency Response: 20Hz-20kHz ±1dB
