* Teac 2-A Mixer + MB-20 meterbridge *
This is a 6 input / 4 output mixer designed
for true multi-channel recording.
Each channel has seperate input selectors, tone control,
channel assign selectors with pan, and input faders.
There is also a MASTER output fader control.
Input selector switch for mic/line or mic att,
which activates a 20dB attenuator pad located,
before the mic preamp stage.
Channel assignments buttons color coded
for the 4 different output busses.
Any signal from a input channel can be assigned
to any, or all of the output channels.
When more than one channel is assigned,
Pan control is engaged = the ability to move the sound
from extreme left or right
in the sound spectrum or anywhere between.
Variable treble control +/-12dB.
Variable bass control +/-12dB.
Crosstalk: Greater then 50dB.
Overall distortion(input to output)=
0.1% THD maximum at nominal -10dB output.
Fader attenuation: Greater then 60dB.
Mic impedance:150~10K. Input impedance:50K or higher. Input level: -10dB (0.3V) Line output/Aux.Output:
Load impedance:10K or higher unbalanced.
Output level: -10dB (0.3volt)
Signal to noise ratio:
One input= greater than 62dB,WTD.
6 inputs = greater than 55dB,WTD.
Frequency response: 30Hz~20KHz,+/-2dB.
Load impedance: Greater than 50K.
Level: -20dB (0.1V) with nominal input.
Input impedance: 15K.
Nominal level: -10dB(0.3V)
Send load impedance:Greater than 10K.
Nominal send level: -10dB(0.3V)
Receive impedance: 15K.
Nominal receive level: -10dB(0.3V)
(6)MIC IN = 1/4 Phone plug. (6)LINE IN = RCA. Normally you would patch the output
of your reel to reel here (line 1-4)
and the master recorder to (line 5-6),
but you have more options because the meterbridge.
(4)LINE OUT = RCA.
ACCESSORY Send/Receive = a patch point for
additional signal processing like different external
EQ unit, Echo,Reverb, Noise reduction etc.
(4) Access with jumpers included.
(4)AUX OUT = Additional line output in paralell
with the main line output.
LINE OUT = (4)Program buss out.
(4)CUE OUT = A foldback after the the mic preamp stage
unaffected by the input fader.
Power Requirements: 117V A.C, 60hz, 5W Weight: 13.2 lbs (mixer with no meterbridge attached) Size:
13-1/2 deep. 13-3/8 Wide. 4 Tall.
* MB-20 Meterbridge *
This bridge is very simple to use and works great with the 2A mixer.
It has 4 VU-meters calibrated to trigger at 10 VU.
Built in headphone amplifier + volume control.
1/4 inch headphone jack located on the back.
Controls the 4x2 monitor mixer and buss/tape monitor selections.
The color coded BUSS/TAPE selectors for each
channel (1-4)let you determine the signal to be fed into the monitor mixer.
You can hear the signal from either
the tape-recorder -DOWN- or the outputs of the
A-2 in -UP- position.
Backpanel has (4) Input and (4) Output RCA. (2) Input sensitive selectors. (4) Foldback RCA Ground connection. (4) Tape Input RCA. L + R Monitor out, RCA. Switched power inlet 117VAC. 60hz, Max 300W.
For connecting the 2-A mixer or other external accessories.
