Страница: 8 / 44

N. POWER CORD SOCKET - Connect the included
power cord to a properly wired AC electrical outlet in
accordance with the voltage and frequency ratings
specified on the rear panel of your amplifier.
O. MAIN FUSE - Protects the amplifier from electrical
faults. Replace a blown fuse ONLY with a fuse of the
type/rating specified on the rear panel of your
amplifier to protect your amplifier and maintain
warranty coverage. Carry spare fuses!
P. STEREO / MONO (BRIDGE) - Selects the Mode of
Operation
for the SM-500 power amplifiers.
IMPORTANT: Understanding the function of this small
switch is essential! Each mode uses different controls
and jacks that require the SM-500 to be turned OFF
while you move the switch and reconnect:
STEREO MODE— The power amplifiers operate
separately as left and right channels with
independent •Master Volumes {K & N}, •Speaker
Outputs {Q & R} and •Effects Loop Returns {U}.
MONO (BRIDGE) MODE— The power amplifiers
operate together as a mono channel with one
•Master Volume {K}, •Speaker Output {S} and
•Effects Loop Return {U}.
Q/R.STEREO MODE SPEAKER OUTPUTS - The SM-500
features both 1/4" phone and Speakon ® speaker
output jacks in Stereo Mode to provide flexibility in
making your speaker connections. Use the Speakon
®
jacks whenever possible to take advantage of their
superior efficiency and locking connectors. All three
jacks on each side {Q & R} are full range and wired in
parallel. Read Speaker Guidelines on the next page
before connecting speakers.
S. MONO (BRIDGE) MODE SPEAKER OUTPUT - One
Speakon
®
speaker output jack is available in Mono
(Bridge) Mode. Read Speaker Guidelines on the next
page before connecting speakers.
T. SPEAKER FUSES - Protects your speakers from
electrical and connection faults. Replace a blown fuse
ONLY with a fuse of the type/rating specified on the
rear panel of your amplifier to protect your equipment
and maintain warranty coverage. Carry spare fuses!
U. EFFECTS LOOP - Multi-purpose jacks: Effects Send
provides a preamp output that includes onboard tone
shaping. Effects Send level is controlled by Gain {B}.
The Effects Return jacks provide power amp inputs
that can be blended in any ratio with the onboard
preamp signal using Effects Blend {J}.
The Effects Loop circuit is on a side chain, isolated
from the main circuit to provide the full sound of your
instrument AND the diversity of your external effects.
The Effects Loop is also located after the gain stages
in the preamp signal path to bypass the noise
generated when effects are connected inline before
the preamp.
Use only shielded instrument cable with
standard 1/4" mono phone plugs with the Effects
Loop jacks. You may need an adapter in certain
situations, such as, when a stereo effects device only
has one stereo output (use a stereo-to-dual-mono
adapter).
1. Effects Loop - Connect Effects Send to your
effects input, then the effects output(s) to either the
Mono Return or Stereo Return jacks according to the
SM-500’s Mode of Operation {P}. If using mono
effects in Stereo Mode, the Mono Return can be used.
NOTE: Set the wet/dry control on your effects units
fully to WET to prevent phasing problems. Set the
input level on external effects to +4dB, (try 0dB if the
unit is being overdriven).
2. Multiple Amplifiers - For additional output, you
can connect an auxiliary power amp to your SM-500’s
Effects Send output (Gain on your SM-500 will affect
the volume levels of both amplifiers).
NOTE: If you
wish to use an SWR ® amp as an auxiliary power amp,
use Mono Effects Return as the input and turn the
Effects Blend control to the maximum WET position.
