Precision 8
OPERATION MANUAL
10
Do not attempt to connect unbalanced microphones (with single-pin connectors) to the
Precision 8. It is not intended to operate with this type of microphone.
CAUTION: We recommend that you avoid “hot-patching” microphone inputs
when using a patch bay at the microphone inputs of the
Precision 8.
Please
TURN OFF phantom power and turn down the gain prior to
connecting or re-patching microphone inputs routed through a patch bay. Failure to do
so may result in transients that can damage the
Precision 8 or equipment that is
connected to its outputs-not to mention your ears!
Electric Instrument Connection: Dual-purpose input connectors 3 are available on
channels 7 and 8. Insert XLR microphone connector for normal
MIC 7 and MIC 8
operation. Insert 1/4" phone plug for use as Direct Input for instruments
DI-1 and DI-2.
DI-1 and DI-2 are controlled by Gain and
φφ (phase) controls for channels 7 and 8,
respectively. The gain range for the direct inputs is from -4 dB to +44 dB.
NOTE: DO NOT use TRS plugs for these inputs as the DI will not function correctly.
M-S (mid-side) Microphone Connection: You may note the M-S (mid-side) connection
symbol below the
MIC 1 and MIC 2 connectors 4 . This is simply a visual reminder,
when using an M-S mic setup, to connect the MID mic to channel 1 and the SIDE mic to
channel 2. See the section “More About M-S Decoding” for more information.
A Word About Cables.....
Most users of the
Precision 8 have invested much time and money in their selection of
microphones and preamplifiers. We recommend that you give some consideration to the
microphone, instrument and output cables you select, as well.
•
Use high-quality, low capacitance cable. Braided shielding and “star quad” type mic
cables will perform better in electrically noisy environments. Manufacturers such as
Canare
, Mogami
(and others) make high performance cable of this type.
•
Some “house brand” cables are made by quality manufacturers, but others can be
inferior. Be careful. Use cables with high-quality connectors (Neutrik
, Switchcraft
,
etc.).
•
Our studio testing has shown that some of the more esoteric guitar/instrument
“super-cables” do, indeed, sound better. Noticeable improvement, but at a stiff price.
Try before you buy!
•
Avoid excessive cable length.
•
Replace damaged connectors.
