SIX INPUT CHANNELS

The Pioneer MA«62 mixer provides Input lacililies tor up to
six microphones. For extra versatility. each oi these chan-
nels otters an alternative terminal tor LINE or PHONO inputs.
(Speclticelly. Channels I and 2 accept PHONO Inputs; Chan-
nels 3 through 8 accept LINE inputs such as tape. tuner. etc.)
Each of the six channets is provided with a control-panel switch
to allow you instant selection or Input source without changing
jack-panel connections.

PROFESSIONAL PAN-POT CHANNEL LOCATION

Two at the six Individually-controlled Input channels are
equipped with simple-to-use panoramic potentiometer: (pan
petal. these continuously-variants rotary pots (on Channel 3
and 4) allow tree sound localization Irom left to right (or any-
where in between). All other channels (Channets 1.2. 5 and
6l are equipped with location switches so that you can select
Lott. Right or Left/Right (Center) output individually.

MIC ATTENUATORS (-- 20d!)

Each ot the six channels is provided with a switched micro~
phone attenuator to instantly reduce signal strength by 2068.
This leature is uselul in preventing saturation (clipping dis-
tortionl ot microphone input signals.

LOW-CUT FILTERS

Each of the six channels Is also provided with a switched low-
cut tiller circuit Ior microphone input These are metul to sup-
press undesirable low trequencies or muddy" human voices.

DESIGNED FOR PRACTICAL USE

The Pioneer Mil-$2 is entirety portabte. operates from any AC
power supply system and Is engineered so that it adds abso-
lutely no unwanted distortion or coloration to the sounds you
channel through it. Its Wide dynamic range and stability are
totally reliable. Extra lectures Include two stereo output ter-
minals. pointer-index markers ior each ot the six long-throw
laders (plus master volume teder). a "scratch board" strip
tor jotting down reminders and a monitor lack (or stereo
