UNPACKING YOUR PREAMPLIFIER
Tools require : none
WARNING - This amplifier uses voltages that coul cause injury or eath. Never
open the amplifier while it is plugge in, an always wait at least 30 minutes after
turning the unit off before unplugging the electrical cor an opening the unit.
Lethal voltages can remain in the electronics after the unit is unplugge .
Your new amplifier has been painstakingly inspected for cosmetic flaws during and after
assembly. In order not to damage the cosmetic appearance of your amplifier it is important that
you follow the unpacking instructions carefully.
1. Open the shipping carton and remove the box containing the remote control and power cord
from the carton.
2. Carefully lift the amplifier out of the carton, and remove the foam pads and plastic bag.
3. Save the packing materials. The packing materials and box have been carefully designed to
protect your valuable equipment during shipping so you don’t want to throw them away.

INSTALLING THE RH-5 HEADPHONE AMP INTO YOUR SYSTEM
lace the RH-5 on a flat stable surface with at least 1” of airspace above the amplifier for
ventilation. Do not place any other electronic components or any other objects on top of the
amplifier.
Insert the IEC end of the detachable power cord into the rear of the amp (shown in Figure 1).
lug the opposite end of the power cord into an appropriate power outlet. It is recommended that
both the headphone amp and power amplifier (if you are using the RH-5 as a preamplifier) are
plugged into the same wall outlet if possible (perhaps using a power outlet strip) in order to
avoid creating a ground loop.
Figure 1
Connecting sources to the RH-5:
Connections are made to the inputs on the rear panel of the amplifier shown in Figure 1. Line
level (CD player, tuner, DAC, etc…) connections are made via the three pairs of RCA inputs or
the pair of XLR balanced inputs. If you have the optional phono card and are using a turntable
connect it to the Line 1 inputs. There is also a grounding lug for the turntable if required.

OPERATION OF THE RH-5 HEADPHONE AMP
Powering up the System:
After all your connections have been made, you are now ready to turn the amplifier on. The
primary power switch is located on the rear of the unit and is shown in figure 1. You can leave
this switch on all the time and it will keep the solid state portions of the RH-5 energized even
though the unit is powered down. Very little power is used in standby and the RH-5 will sound
its best shortly after turn on. The power button located on the front panel is shown in figure 2 and
is used to power the RH-5 on and off between listening sessions. Your amplifier features soft-
starting to prolong tube life as well as to suppress turn-on transients. A countdown timer on the
display shows the time remaining before the RH-5 is ready to use.
When the RH-5 is turned on or off with the rear switch you should not have headphones plugged
in as there are noise transients that could damage sensitive headphones. During normal turn
off/turn on with the front button this is not a concern. When using the front power button all
previous listener settings are retained such as volume and input selection.
To avoid source transients turn on all sources prior to turning on the RH-5 and turn off the RH-5
first when finished listening.
NOTE – The RH-5 will not play music for approximately 20 secon s after power on
while the amplifier goes through its sequential start-up.

Hea phone Connections:
The RH-5 is designed to accept standard ¼” (6.3mm) TSR jacks, 3 pin XLR connectors and 4
pin XLR headphone cables as shown in figure 2. The RH-5 is capable of operating multiple
pairs of headphones simultaneously.
Switches, Buttons an Controls:
Volume Control
The volume control has 185 steps which vary in 0.5 dB increments. At turn on the RH-5 defaults
to a relatively low volume. The volume can be turned continuously until reaching a reading at
either 1 (min) or 185 (max).
Selector Button
The input selector button accesses four different sets of inputs. Each successive push will step
through the three RCA inputs and the XLR input. Note that if the optional phono board is
installed that it replaces the Line 1input.
Mute Button
ushing the mute button mutes the headphone outputs and the variable outputs. The letter “M”
appears on the display to show that the RH-5 is in mute.
Gain Button
ushing the gain button steps the output level through three different gain settings. The
difference between the gain settings allows a wide range of volume operation to accommodate
various headphone sensitivities. For example, if you have very sensitive headphones you can use
gain level “1” and have a useful span of the volume control before the RH-5 plays too loudly.
Conversely, if your headphones are low sensitivity you can use gain setting “2” or “3” so that
you get full volume. There is no performance advantage between the gain settings.
Display On/Off Switch (locate in the volume knob)
ushing in the volume knob will toggle the display on and off. When the display is “off” only a
small blue LED segment remains to show that the RH-5 is turned on. When the display is
toggled back on the current input and volume are displayed. You can adjust the volume level
while the display is off.
Using the RH-5 as a stereo preamplifier:
There are two pairs of variable (preamplifier) outputs on the RH-5 which can be used to drive an
external power amplifier. One pair is RCA and the other pair XLR (balanced).
If you are using the RH-5 as a preamplifier turn on the RH-5 first and then the power amp. Turn
off the power amp first and then the RH-5. Also note that the mute button will mute both the
headphones and preamp outs. If you want to listen to the headphones only you will need to turn
off the external power amp.

Remote Control
The RH-5 hand held remote provides most of the functions located on the RH-5 front panel.
Note that the on/off button requires being held down for a moment to avoid accidental turn
on/off.
Phono Amplifier (optional)
The RH-5 hono board provides a high performance phono section that is suitable for the vast
majority of phono cartridges available today. It is user configurable and has adjustments for gain,
and resistive loading. The RH-5 w/phono option is shippe with the gain set at 44 B an the
loa ing set at 47K. This set up is appropriate for most high output cartridges. Before removing
the cover to make any loading or gain adjustments, power off the RH-5 and let it drain off any
voltages for at least 30 minutes. Leave the RH-5 plugged into the wall during this time so that
the voltages can drain down properly. After the RH-5 has sat for at least 30 minutes disconnect
the power cord from the wall or rear of the unit. lease note that best results will be obtained
with cartridges of 0.5mV output and higher. Lower values will work but you may not achieve the
desired maximum volume with low sensitivity headphones.
Setting the cartri ge loa ing – Remove the 10 cover screws using a #2 hillips screwdriver
and pull off the cover.
WARNING - This amplifier uses voltages that coul cause injury or eath. Never
open the amplifier while it is plugge in, an always wait at least 30 minutes after
turning the unit off before unplugging the electrical cor an opening the unit.
Lethal voltages can remain in the electronics after the unit is unplugge .

The cartridge loading DI switches are located near the rear of the optional phono board (figure
3). It is important to point out that the cartridge manufacturers recommended loading should be
considered as a starting point and not an absolute. Systems and turntable setups vary
significantly and if you want to get the most out of your analog setup, take the time to find the
settings that sound best in your system.

DIP switches for resistive loading
Slide switches for setting the phono gain.
Resistive loading – There are two sets of DI switches (S3 and S5) for setting the resistive
loading (one per channel). The four switches are labeled 1,2,3 and 4. Figure 3 shows the switches
in the 300 Ω position. The loading options are given in Table 1 on the following page.

Table 1
Setting the phono gain - The two slide switches S6 and S4 are used to set the gain and are
located on the front right side of the optional phono board (Figure 3).
If the switches are pushed towards the rear 56 dB of gain is provided which is sufficient for most
low output cartridges. When the switches are pushed forward (towards the front of the RH-5)
the phono provides 44 dB of gain which is suitable for moving magnet (MM) and high output
moving coil (MC) cartridges. A setting of 56 dB gain and 300 Ω loading is shown in Figure 3.
Phono noise – lease note that the phono amp is high gain and as you turn up the volume you
may start to increase the noise floor compared to the other inputs. While the RH-5 phono board
has a Signal to Noise ratio of over 70 dB some noise is inevitable with a phono preamp
(particularly through headphones). The volume control is limited to 160 steps in phono.
