ART Pro Audio SGX LT - Guitar Preamp with F/X - Manual (Page 8)

INSTALLATION
The SGX LT may be used in a variety of setups including: mixing consoles with
effect send and return facilities, straight into guitar or power amps, and in the
effects loop of an amplifier. Self contained in an all steel single high 19" rack
mount case, the SGX LT is designed for continuous professional use. For touring
rack applications, care should be taken to support the units rear if the rack
might be subjected to mechanical shock like dropping. NOTE: The front panel may
bend if no rear support is provided. Mounting location is not critical, but for
greater reliability we recommend that you not place the unit on top of power
amps, tube equipment, or other sources of heat.
POWER
This device is AC powered via a standard 3 conductor grounded power cable. Plug
into any standard AC receptacle. We recommend the use of a surge protector to
decrease the chance of equipment damage due to voltage surges or spikes on the
line. For your own safety as well as the safety of others, do not remove the
ground pin of the cable. Refer to the rear panel or the specifications for proper
operating voltages.
CONNECTIONS
Audio connections to the SGX LT are made at the front and rear of the unit via
professional 1/4" phone jacks. The MIDI connection is accomplished via a five pin
"DIN" jack on the rear panel.
INPUTS:
There are two mono inputs available in the SGX LT. You can use both input jacks
at the same time. However, the preamp output will be summed with the Line In
input and then the combined inputs will be sent to the digital processor.
INSTRUMENT INPUT
The Instrument Input on the front panel is a single ended (unbalanced)
configuration with an input impedance of 470K ohms. This input is a direct input
to the SGX LT's solid state preamp. Plug in all types of instruments to this
jack. You may also plug "line" level devices into this input.
LINE INPUT
The Line Input jack on the rear panel is a direct input to the digital processor.
This input is a single ended (unbalanced) configuration with an input impedance
of 1M ohm. The nominal operating level for this input is (-)10dB. Hook up high
output instruments, recording devices, other outboard signal processors, and
effects loop sends to this input.
OUTPUT
The LEFT and RIGHT outputs are single ended (unbalanced) with an impedance of
1.5K ohms, and can provide a stereo or mono output. When both outputs are used
with one or both of the inputs, a stereo image is produced. If you do not want
both output signals combined (such as only one delay time required), plug a dummy
plug into the unused output. If you are only using one output use the Left
output.
